Paintball is a sport in which players eliminate opponents from play by hitting them with dye-filled, breakable, oil and gelatin paintballs usually shot from a carbon dioxide or compressed air (Nitrogen) powered “paintball marker”.

Paintball draws a wide array of people, and the Sporting Goods Manufacturer’s Association estimates that over 5.4 million people played the game in the United States in 2007, with over 1.5 million playing at least 15 times that year. Insurance statistics show that paintball is one of the safest sports, with fewer injuries per exposure than sports like football, soccer, basketball, baseball, golf, and bowling.

Games can be also played either indoors or outdoors and take various forms, of which some of the most popular are woodsball, scenario, X-Ball and speedball. Rules for playing paintball vary widely, with most designed to ensure that participants enjoy the sport in a safe environment. The sport requires a significant amount of equipment.

A game of paintball usually involves two opposing teams seeking to eliminate all of the other team’s players or to complete some other objective, such as retrieving a flag, eliminating a specific player, or other paintball variations. Depending on the style of paintball played, a paintball game can last from seconds to days.

So, This is Your First Time Playing Paintball. Are you a little nervous about trying paintball? We have pulled together some facts and information that should help put your mind at ease and allow you to enjoy your day at CPX Sports!

First, to put your mind at ease, here are some statistics on paintball…

  • You have less of a chance of being injured playing paintball than you do golfing, boating, and even bowling! Statistics are based on all injuries requiring medical attention or causing the participant to lose at least 1 day of work. (Source: SGMA International)
  • In 2003, 9.8 million people played paintball and paintball has consistently been ranked among the top 5 extreme sports since 1996. (Source: American Sports Data)

OK, now you know the stats, but what is paintball? Paintball is more closely related to tag and dodge ball than to any other sport or activity. Paintball games last 10-20 minutes and have set objectives ranging from capture the flag to elimination of the other team (like in dodge ball). In all paintball games, a player is eliminated when they are “marked” by a paintball. Here are some common questions people have about the sport of paintball.


What is a Paintball?

A paintball is a round, thin-skinned gelatin capsule, with colored liquid inside of it. Paintballs are similar to large round vitamin capsules or bath oil beads. The fill inside paintballs is non-toxic, non-caustic, water-soluble and biodegradable. It rinses out of clothing and off skin with mild soap and water and they are even edible, although we don’t recommend it!

What should I wear?

We suggest you wear loose fitting, comfortable clothing that cover as much exposed skin as possible. Hooded sweatshirts, sweat pants, and good running shoes with ankle support are suggested. CPX Sports has a Pro-Shop where you can purchase hats, gloves, and other paintball apparel including disposable camo jumpsuits.

What extra things should I bring?

During the summer months always carry bug spray and sunscreen. Application of bug spray should be done before you play and will keep the pests off you while on our many courses. Avoid using bug spray near your goggles. It will damage goggle lenses and other plastic equipment. In the winter lip-balm and good warm gloves are a must. Remember, we are outdoors so dress for it.

Does getting shot with a paintball hurt?

William Shatner said it best when he visited our park: “The sting of the paintball is part of the mystique of the ballgame. So, the kick of running and jumping, dodging the paintball goes right back to your childhood. And the competition of trying to make the points to win the overall thing is a rush.” So, while getting “marked” by a paintball might sting a little, the sensation is similar to getting snapped by a rubber band and will usually go away in a couple seconds.

What kind of safety precautions do you take?

The most important safety precaution in the sport of paintball is the full face goggles. We require all participants to wear full-face mask system with ear protection. All visitors to CPX Sports are also given a safety briefing every time they visit park. This briefing explains the important safety rules at the park, along with how to properly use the equipment and play the game. We also require guests to chronograph their markers before each game. This allows us to make sure no guests are exceeding the maximum velocity of 280 fps (feet per second) or are in full auto or burst mode.

Can I bring and use my own equipment?

Yes, but we will inspect your equipment to make sure it meets our safety standards.

  • All goggles must be full-face masks and be unaltered. There can be no cracks in the lenses at all.
  • Paintball markers must be semi-automatic with a trigger guard. We do not allow full auto, double fire trigger systems (double triggers are ok), markers with ramping mode enabled, or burst mode. Any markers with full auto capability must be able to lock it down and not have the ability to quickly switch to full auto while on the field. If there is a question on if your marker can be used here, a CPX Sports staff member will make it. The decision of CPX Sports staff is final.
  • Barrel socks are required on all paintball markers.
  • All CO2 or High Pressure tanks must be in test date. High-pressure fiber wrap tanks may not have any cracks or fraying and can’t have any stickers, decals or other coverings on them.
  • We do not allow silencers, smoke grenades, paint mines or multiple paintball launchers.
  • Maximum velocity is 280 fps.

How old do you have to be to play paintball?

You must be at least 10 years old to play paintball. Anyone under 18 must have an Underage Waiver signed by their parent or guardian to participate. Please print out the form below & sign and date the waiver. Bring the completed form with you on the day of your event. Download the Under Age Waiver Form here!

Do the Underage Waivers need to be notarized?

No. If your form is not notarized, it will be good for the one day only. However, if your form is notarized (we have 2 notaries here at the park and will do it for you free of charge if your parent is with you), we will keep it on file until the child is 18.

What kind of equipment do you rent?

We rent all of the equipment necessary to participate in the sport of paintball. Our standard rental package will include a semi-automatic Tippmann 98 paintball marker with a barrel sock, a hopper, a HPA tank, and a full facemask with anti-fog lenses. We also rent paintball shirts, ammo pouches, tactical vests, chest protectors, and various upgrades for a small additional charge.

What is required to rent equipment at CPX Sports?

A valid photo ID is required for all equipment rentals. You will have to give your ID card to the equipment room staff when you pick up your rental equipment. Your ID card will be returned to you when the equipment is returned in good condition. You will be charged for lost or damaged equipment at the rates posted at the equipment room.

But what if I do not have an ID Card?

A parent or guardian or another individual must be willing to assume responsibility for your equipment’s return and condition. Individuals with a valid ID card can have more than one set of equipment secured in their name.

Does the park close for inclement weather?

No, CPX Sports is open year round rain or shine! The only time we stop play is if there are lightning strikes on or near the park grounds. We will resume play as soon as the storm passes. Please be sure to check the website for current park hours.

Do you have any indoor paintball fields?


Can I bring my own food and/or beverage?

No. CPX Sports does not allow any outside food or beverages anywhere on the property. We do, however, offer a full concession stand with a variety of snacks, pizza, hot dogs, and beverages.

Can I bring my own paintballs?

No. CPX Sports is field paint only. Any players found to be using off-field paint will be ejected from the park. No exceptions.

How many paintballs will I use?

The average player goes through 750-1,000 paintballs in 4 hours of paintball play.

Can I get my tank filled there?

We provide air fills for players with a paid admission only for CO2 or HPA fills up to 4500psi. We also inspect tanks for dates, so make sure your tank is up to date!

How much does paintball cost?

A day of paintball (including admission, rental equipment, and your paint) will cost you around $58, depending on how much paint you shoot. We do offer memberships that will save you money if you visit the park more than 2 times a year.

The most important rule in paintball is that all players must wear a protective goggle system or mask at all times when they are playing or near other people who are playing. While paintballs will not cause permanent injury to most areas of the body, the eyes, and to a lesser extent the ears, are vulnerable to serious injury if hit by a paintball. Paintball masks are specifically designed for the sport, and the goggles are capable of withstanding a direct hit from a paintball traveling at well over 300 feet per second (90 m/s), the safety limit adopted by paintball marker manufacturers. The lenses of the goggles are composed of either single sheets of tough plastic, or thermal lenses, which cut down on fogging. Most masks have flaps that protect the ears, and some include a visor to shade the player from sunlight. Some players use masks that cover the entire head for maximum protection, while the majority of tournament-level players choose smaller masks that offer a wider field of view, better hearing, vocal communication and more venting. Recently, small timers were created to fit in the goggle, alerting the user to a certain time in the game.

A safety device comprised of a cloth or neoprene pouch placed over the opening of the barrel and attached to the marker via a cord. These are usually required by commercial fields, to be used whenever the player is not on a field. They prevent an accidentally discharged paintball from leaving the barrel and causing injury. Forgetting to replace it after leaving a game and entering a safe zone will usually earn a warning. Repeated infractions will often result in ejection from the site. This is done for liability reasons and to lower possibility of unexpected injury to anyone around, especially important when involving eye safety.

Barrel socks are now preferred over barrel plugs because of the reduced possibility of discharging the safety equipment from the marker. When using a barrel plug, the first accidentally fired shot will shatter inside the barrel against the plug, pushing it at least partly out of the barrel. The second or third shot will likely dislodge the plug completely, meaning further shots pose a danger to surrounding players. With modern markers easily capable of firing five or more shots in a fraction of a second, barrel plugs simply do not provide an adequate guarrantee of protection. Furthermore, a discharging plug is a hazard in itself, as it can be fired with some speed out of the end of the barrel.

A barrel sock, by contrast, does not adhere rigidly to the end of the barrel but is instead attached with elastic. If a paintball is accidentally fired, it passes out the end of the barrel and is caught by the barrel sock. The momentum of the paintball is absorbed by the elastic, which then springs back into position, pushing the paintball harmlessly out the bottom of the sock. Repetitive firings therefore pose no threat to safety, and the paintball does not make a mess of the inside of the barrel.

To “blind fire” is to discharge a marker around a corner or over an object with your head still behind that object or corner, making you unable to see where you shoot. Blind firing is discouraged on many fields, for potential safety implications. As the shooter cannot see where their shots are landing, they could accidentally fire at somebody point blank, hit a referee, hit a person that had removed their mask (also a major safety violation), or otherwise cause damage or injury through indiscriminately firing paint at an unseen target, although many players use the arc of a paintball to shoot at someone they can’t see over low bunkers. This tactic is not advisable.

In addition to the mandatory use of masks, paintball markers must not fire paintballs that exceed a certain velocity. The industry standard maximum velocity for safe play is 300 FPS (feet per second), about 91 meters per second.

Many commercial paintball facilities mandate a lower velocity, usually around 280 feet per second (85 m/s, 300 km/h or 190 mph), with a muzzle energy of approximately 11 joules, in order to create an extra margin of safety. Due to the closer proximity of players to each other, a majority of indoor paintball facilities cap marker velocities at an even lower level, between 220-250 FPS.

Paintball velocity is measured using a chronograph. Chronographs are standard equipment at commercial paintball facilities, but should be purchased if not playing at a commercial location. Players who play without first using a chronograph put themselves and other players at risk. Changes in temperature greatly affect a paintball’s velocity when propelled by compressed gases that undergo phase change, such as compressed carbon dioxide, the most commonly used propellant. Markers should be chronographed several times throughout the day. Paintball markers should also be chronographed after any adjustment, replacement of parts, such as the barrel, or paint as these changes generally affect the paintball’s velocity.

Compressed air is rapidly replacing CO2 as the most commonly used propellant. This is because it provides a constant and stable pressure that isn’t subject to changes in outside temperature and is also easier to refill and more environmentally friendly. Further, as carbon dioxide is a known attractant of certain insects known to prey on humans, it has been speculated (though not conclusively proved) that use of compressed air can reduce the likelihood of being stung or bitten in a wooded setting.

To overshoot (also called bonus balling or lighting up) is to repeatedly shoot a player after they are eliminated. Generally, it’s considered a few extra shots after a successful break. This practice is frowned upon by nearly all players. There is no set rule as to what constitutes overshooting. It varies in recreational play, with each field having its own individual set of rules. However, in tournament play, it is generally up to the head referee’s discretion. The penalty for overshooting in tournaments is usually a 2-for-1, the elimination of the guilty player as well as another player from his or her own team, but each tournament has its own set of rules.

“Ramping”, the term used to describe the firing of a paintball when the trigger is pulled, and another when the trigger is released, is a popular but controversial style of shooting a paintball marker. Although many games, and fields allow ramping, there are still specific rules to this that must be adhered to. CPX Sports does not allow ramping in both Open Games and Private Games. However, CPX does allow ramping and full-auto at Scenario and Big Games. PSP ramping mode is capped at 12.5 bps and full-auto at 10 bps.

Players eliminate each other from the game by hitting their opponents with a paintball that breaks upon impact and leaves them visibly marked with paint. Rules on how big a paint mark must be to count as a hit vary, but a paint mark from a paintball that breaks on some other object before striking a player, referred to as splatter, generally does not count as a hit. Once a player has been marked, they are eliminated from the game.

Most fields consider hits on any body part, clothing, gear, or object the player is carrying or wearing as an elimination. This includes the marker, backpack or an object picked up from the field, such as a flag or a pod. Some fields do not count hits on the marker or head or both, or other areas of the body as an elimination, such as anywhere but the torso, or require more than one hit in certain areas for elimination. These special rules are usually found in scenario paintball games. Wearing baggy clothing helps reduce the chance that a paintball will break on you.

If a player is uncertain whether a mark they have received is a valid hit or not, possibly because the mark is from the spray of a paintball breaking on another nearby object, they cannot see the part of the body where they have been struck by a paintball, or because the paintball may have been shot by a player who had already been eliminated, the player should ask a referee or a nearby teammate to determine whether or not the player has a valid hit. This request is commonly referred to as a ‘paint check’, and is most often requested by the player yelling the words ‘paint check’ to a nearby referee. Some game rules allow a referee to call a player ‘neutral’ during a paint check so that the referee can more closely inspect a player. If a player is called neutral, they must discontinue play while being checked and opponents may also not fire or advance on the neutral player.

Players may also be eliminated from the game for reasons other than being hit by a paintball, including calling themselves out by saying “I’m hit!” or “I’m out!”, from paint marks from paint grenades or paint mines in games where such equipment is allowed, or due to a penalty, such as stepping out-of-bounds or leaving the starting station prior to the beginning of the game. Because players who call themselves out are eliminated even if they are not actually hit, players should always check to see if a paintball that has hit them has indeed left a mark. A paintball may simply bounce off a player’s body without breaking, which does not count as a hit. Players may also call for a paint check on another player if they believe they have marked an opponent to ensure the player is promptly eliminated from the game, especially if the opposing player may not be aware they are hit or may be attempting to hide or remove a hit. Removing a hit and continuing to play is a severe form of cheating commonly known as ‘wiping’ and can result in severe penalties, including being permanently banned from the playing location at a recreational or commercial facility. In tournaments, a “3 for 1” penalty may be called, where the offending player and an additional three teammates are eliminated from play.

Recreational fields often suggest a player within a certain distance of an unaware opponent, usually 10 to 15 feet, should offer the unaware player’s surrender by yelling “Surrender!” (or Point Blank or freeze) before they may open fire. If the opponent complies, either verbally or by raising their hand or marker, they are considered marked and are out of the match. However, if they refuse or attempt any hostile action, such as turning to fire, the challenging player may fire upon them. Getting hit by a paintball from close range can be painful, and it is considered polite and good sportsmanship to offer an opponent the opportunity to surrender when possible instead of unnecessarily shooting at close range. It is also good policy to fire at their foot so as not to cause pain because of their boots.

This “rule” is subject to great interpretation between fields, and even between players, for a variety of reasons. A common field interpretation of the surrender rule is not to prevent two players in a heated exchange from shooting each other close range, but rather from having an experienced player mowing down a first-timer who is in shock and hiding in a bunker. Interpretation at the other end of the debate often stipulates an automatic elimination for any move where a surrender would be offered, such as surprise or bunkering. This strict variant is often called a “bunker tap rule,” to differentiate it from a more lax interpretation.

New players can become packed with adrenaline in such situations, and often attempt to fire out of reflex. Thus, experienced players often decide to offer a surrender only in situations where the opponent is completely off guard, and will be too shocked to make any reflex action. For these reasons, when a bunkering move is executed, even in recreational play, a surrender is rarely offered unless field rules absolutely require it.

In tournament play there is no enforcement of a surrender rule. When a player catches an opponent off guard, they will fire until they see that the paint breaks, or until a referee calls the opponent out. Moves such as a ‘run through’, where a player runs down the field shooting opponents as he passes them and continuing on, have developed over time and are now important plays. Another popular move is “bunkering”, where a player charges up to the bunker or barricade that an opposing player is behind and shoots them from over the top or around the side of the bunker. Players also sometimes call themselves out if they are the last player, just in plain fear of getting hit.

Some players use the term ‘mercy kill’ rather than ‘surrender’. However, the industry itself is trying to drop the term ‘mercy kill’ in an effort to distance itself from a militant image.
