You may mark a definite boundary with string or chalk, or simply mark the corners with flags or other suitable markers. Any ball that crosses the boundary is placed in three feet (or the length of a mallet), nearest the point where the ball crossed the boundary. Any ball less than three feet (or the length of a mallet) from the boundary is also placed in the full distance.
Wicket and Hit
The striker ball cannot both score a wicket and make a roquet on the same stroke. Whichever happens first takes precedence.
A ball scores the turning stake by hitting it in the correct sequence.
The striker earns an extra stroke (called a continuation stroke) for the striker ball by scoring a wicket, or the turning stake, or by taking croquet. The continuation stroke is played as the balls lie. In general, continuation strokes are not cumulative. For example, if the striker ball scores a wicket while taking croquet, only one continuation stroke is earned.
If the striker ball makes a roquet while taking croquet, there is no continuation stroke and the striker immediately takes croquet from the ball that was just roqueted.
If the striker ball scores a wicket and the turning stake on the same stroke, only one continuation stroke is earned.
The one exception is that two continuation strokes are earned if the striker ball scores two wickets on one stroke. And if the striker ball scores a wicket or stake or makes a roquet with the first of these two continuation strokes, the extra stroke is forfeited.
Rover Balls and Scoring the Finishing Stake
A ball that has scored all the points except the finishing stake is called a rover ball. Any rover ball that hits the finishing stake, whether or not it is the striker ball, has scored the stake and is removed from the game. Play continues in the usual sequence, skipping over the missing ball. The game ends when both balls of a side have scored the finishing stake.
A rover ball may roquet each other ball no more than once per turn.
Stake and Hit
The striker ball cannot both score the stake and make a roquet on the same stroke. Whichever happens first takes precedence.
The following variations can be used singly or in combination.
Variation 1: Out-of-bounds penalty
If any ball, other than the striker ball during a roquet stroke, goes out of bounds, the turn immediately ends.
Variation 2: Carry-over deadness
A ball that has roqueted and taken croquet from another ball may not roquet that ball again until it scores its next point. If the striker ball does hit such a dead ball, no extra stroke is earned and the balls remain where they come to rest. It is highly recommended that deadness is tracked on paper or with a deadness board.
Variation 3: Triples
Played with six balls and two sides: the blue, black, and green balls against the red, yellow, and orange balls. The sequence of play is blue, red, black, yellow, green, and then orange.
Variation 4: Poison
A rover ball is a poison ball. When a poison ball hits another ball, that other ball is removed from the game. If another ball roquets a poison ball, the poison ball is removed from the game. If a poison ball passes through any wicket, it is removed from the game. The object of the game is to be the last player with a ball still in the game, so this is usually played as "cutthroat" (every man for himself).
