Picture of Indoor Chamball
Indoor Chamball is a dodgeball-like sport played in a small indoor court.

If you like what you see here, we've also invented an outdoor team version that includes a new rope swinging mechanic for demolishing your foes. Check it out at chamball.org .

Object of the Game
Deplete your opponent's points by hitting them with the ball anywhere EXCEPT the elbows to fists and knees to feet .

Let's get started...

Step 1: Preparation and Supplies

Picture of Preparation and Supplies
Before you can play Indoor Chamball, you need a couple of things.

1.) A size 3 soccer ball. It's like an indoor or kids soccer ball.

2.) A squash court - for a nice tight game with lots of ricochets.
A racquetball court - for a more endurance and strength focused game.

3.) A lot of water...preferably beforehand...it's gonna get hot in there.

4.) OPTIONAL boxing hand wraps to protect your knuckles and wrists.

That's it! Let's Begin.

Step 2: Beginning Play

Fundamental Rule
Both players may only hit the ball with the protected places of the body. These are the forearms to fists and knees to toes.

Beginning Play
One player stands in the left starting area and the other player stands in the right. They each have 10 points to start. The older player serves first.

The server tosses the ball up and strikes it at the serving wall above the bottom serving line. As soon as the ball is struck, both players are free to move to any position on the court. The server may not touch the ball again until the other player has done so.

Moving on to Active Play

Step 3: Active Play

Active Play
While the ball is bouncing, it is in Active Play and can be hit by either player after it is touched by the non-server. If at any time the ball stops bouncing and rolls for over three consecutive seconds (roll-out) or stops at all (ball-stop), Active Play stops, and the last player to touch the ball re-serves. If there is a roll-out or a ball-stop after a serve, the non-server becomes the server.

No points are lost for a roll-out or a ball-stop

On to Scoring, the meat of the game!

Step 4: Scoring

If either player touches the ball with any unprotected place at ANY TIME AFTER SERVICE, play stops, the player who was touched loses a point and the other player re-serves the ball.

Very simple.

Once a a player loses their last point, the game is over and the other player wins.

Now for Penalties

Step 5: Penalties

Time Limit
The overall game has no time limit. If the ball has only touched one player for 60 seconds after a serve, that player re-serves the ball.

If the ball touches a surface other than the starting wall first on a serve, the serving player re-serves. If they miss again, they lose a point and the other player re-serves.

Illegal interception
If the server touches the ball first after they serve, they lose a point and re-serve to the other player.

Trapping, Palming, and Pushing
If a player hits the ball with their palm, traps it on the ground or with their body, catches it, throws it, or pushes it, they lose a point and the opposing player re-serves. As a rule, players should make sure that every bodily contact with the ball is a strike with a protected area and lasts for less than a second. Any other kind of contact is a foul.

Step 6: Penalties Continued

Wall hugging
No sustained contact with walls or corners. A single warning is given and the player loses a point for each occurrence on subsequent wall hugging fouls.

Aggressive Contact

-Incidental minor contact is inevitable and not penalized.

-Bodily contact with another player that lasts for longer than one second is penalized with a stop of play, separation, and a re-serve from the player who hasn't touched the ball last.

-When a moving player collides with a static player, the moving player is at fault.

-When two moving players collide, the person who hasn't touched the ball last is at fault.

-Punches and kicks that land on the opponent are the fault of the assailant.

In all of the above cases, the player receives a single warning with no loss of point.

Upon subsequent fouls, the player loses a point for each occurrence.

If the sustained bodily contact, collision, or strike to the body has injured a player beyond the point of continuing play, the assailant has lost the game.

That's it! Play safe!
wow i should suggest this for a PE class

That'd be great to see high schoolers engaged in squash court combat.

If you're interested in other invented sports, check out chamball.org for Outdoor Chamball. It has a similar core rule, but with the addition of having the ball on a rope for a new range of moves in addition to striking.

If you're in the New York City area, you can also come play with us during one of our weekly pickups.

Four of us just played what we called 'Team Chaam', where two teams of two battled against each other in a racquetball court. Each team got 10 points, and all but one rule remained the same- Instead of the ball having to hit a wall between each touch, you could 'pass' it between teammates as long as the ball only touched the protected body areas. The team passing added an interesting new element, as you have to defend against multiple attackers. On the other hand, you have multiple targets :-)

That's so coincidental! We just recently finished an outdoor team version of chaam (now called cham ball).

Here's a video:

We'll have a new instructable for the outdoor team version soon. It's somewhat similar to what you've described with passing. Now, there's also use of swinging the rope for radial strikes and holding and passing the ball.

If any of you guys are around the NYC area, we're going to be playtesting a more accessible outdoor version soon. The rules will change a little bit, but the core of "martial arts meets dodgeball" will remain.

What a great game you guys have here. I could see this getting pretty intense. I know that I'm definitely going to get a few friends together to try this out.

I've played this 3 times now with my buddy Mike. We play in a racquetball court with a size 4 ball and it's quite a work out. Besides a few blisters on our toes and knuckles, this game hasn't really left us very damaged (much less than I had anticipated). Go out there and play! Watch out for the laser-fast kick to the face from across the court though, that's a killer!

Thanks! We're having a ton of fun playing it. The school we go to is even considering making it a club sport in the fall!

That looks pretty cool (except 1:45 in the video.. savage >_<). I like the way the players do those Ong-Bak style blocks with one shin and both forearms, this game might be a good block-and-counter martial arts exercise.
Asca (author)  PKM6 years ago
Totally. The most natural ways to block those unprotected areas are to raise a front leg and put your fists up in front of your face. It automatically starts to look like martial arts because they share similar goals: "hit him where he's weak"
yah, i know the block(7 year's of martial arts exp)
raise the right leg, put your left forearm 45* up and your left one 45* down.
it would be perfect!!! :P
