If you receive a lift or contact on the third or fourth turn of the game you have to play with the ball not yet in the game, but if you have a contact, this overrides the rule that states that this turn should be played from a baulk-line. If you peg out a ball you still concede lifts to the opponent. Level play and handicap play do not use law 36. The means of judging if one ball is wired from another is the same in both games. In International rules if the adversary is responsible for the position of a ball and it is wired from the rest of the balls on the court, the striker can choose to lift that ball and play it from either baulk-line.
Rover is run in the opposite direction, away from the peg.
A ball that has made rover can roquet each ball once in a turn and is simply alive again when it starts its next turn, like any other ball. A ball that has made rover in the International game cannot gain a continuation stroke by running a hoop. If the striker's ball, being a rover, roquets another rover and that ball hits the peg, that ball is pegged out and the striker's ball has no ball upon which to take croquet, so the turn ends. So if you rush to the peg in International rules, you should try to hit it slightly short and off-line to avoid rushing into the peg. In International rules there is no shot clock, though there is a rule known as 'expedition in play' that says it is the players' responsibility to get on with the game.
