An out in kickball is when a the fielding team successfully gets the kicker or base runner to make a mistake on the field. When a player is ruled out, they are not forced to leave the game. On the contrary, the player must return to the bench and wait for his turn to be at-bat again. There are lots of ways players can get out in kickball:
A strikeout is when the kicker is called out after getting three strikes thrown by the pitcher. In kickball, there are lots of ways to get a strike. Strikes are called by the head umpire who stands behind home plate. The head umpire uses something called the strike zone to determine if a pitch is a strike or ball. If the kicker gets three strikes, it's a strikeout. If the kicker gets four balls, he gets to go to first base for a walk. In some kickball leagues, the kicker will be called for a strikeout if they kick more than four fouls while at-bat.
A catch in kickball is when a fielder grabs a kicked ball out of the air before it touches the ground. The fielder must secure the ball for it to be ruled a successful catch. For example, if the kickball touches the ground while the fielder is making the catch, the kicker will not be called out.
A force out is when a fielder, typically a baseman, gets possession of the ball and touches the bag with his foot while holding the ball. Touching the bag with the ball at first base will always result in an out, since the kicker is required to go to first base. Force outs can only happen at second base, third base, and home plate if there is a kicker occupying the preceding base.
A tag out is different from a force out since the fielder physically takes the ball and touches it to the body of a base runner. Tag outs only result in a player being called out if they are unsafe or off base. There are usually strict rules in kickball that state a player can not tag a base runner out in the head by pegging or throwing the ball at them. However, some kickball leagues allow for pegging below the knees. Make sure you consult the rulebook for your kickball league, since you could cause serious injury to another player if your peg them with the ball.
There are lots of interference types in kickball. If a spectator, player, referee, fielder, or obstruction interferes with the game, then interference will be called. Interference results in the previous play being discounted. If a base runner interferes with a fielder's attempt to field the ball, such as kicking it while running the bases, he will be called out by the referee.
Base runners must touch the bases in order of first base, second base, third base, and home plate to score a run. If a base runner runs the bases out of order or doesn't touch a base, he will be ruled out.
