Klaymen have been observed engaging in a number of nonsensical recreational activities. The exact rules to these games are not understood, if any rules actually exist.
Klay World's version of tennis has very little resemblance to the real-world version. In fact, it has more similarities to baseball.
Only two players are required, one pitcher and one hitter. The pitcher stands on a plate and the hitter stands a short distance away. When the pitcher throws, the hitter attempts to hit the ball and have it hit a marked target. If the ball hits the target, the pitcher wins. The pitcher only needs one point to win a game of tennis.
The Klay World version of baseball is another two-player sport. Like tennis, it hardly resembles the actual sport that it is meant to imitate. Klay World baseball seems to be little more than a game of catch. Baseball bats and gloves are not used.
Two players will stand across from each other, one holding a baseball and one without. It appears to be customart for observers to yell 'Hey, batter, batter, batter!' (a chant used in real baseball to distract the batter) despite there being no actual batter. The klayman with the ball will then throw it at the opponent and if he catches the ball, the thrower is out. It is not understood how the pitcher can score or why he would throw the ball to the person who can easily get him out.
In 'Klay World: Karate Master', the Karate Teacher was seen congratulating the Karate Master that his training was complete, and praising him by ranking and giving him a blackbelt. The Karate Teacher soon warned him to only use his karate skills when necessary, but instead, the Karate Master murdered his teacher, and used his skills for murder.
The rules to Funny Sticks are impossible to determine. All that can be understood is taken from observing an unfinished game.
Funny Sticks seems to be a turn-based game which consists of two or more participants. One of the players is relentlessly beaten to the ground and stabbed in the back with three sticks from each player. The next step of the game has something to do with apples, but has never been seen. Taking the sticks out of the player's back is considered cheating.
In 'Klay World: Grenade Gregory', a game is shown where three differently-colored blocks are thrown on the ground, and Klaymen bet on which one is going to win. The blocks do not move, so it is unknown how a block wins the game, neither is the game given a name.
