It is entitled to another blow after roquet-croquet at any rate; therefore the roquet is not necessary to give continuance of tour.
51. A rover fails to roquet-croquet if the other ball is not moved, and the tour terminates unless another ball is roqueted on the same blow.
The blow not being a roquet-croquet, a point must be made to entitle to continuance of tour. A roquet-croquet is precisely like a roquet when the balls are in contact. (See Rule 17 and remarks.)
52. A rover is struck out whenever it touches the starting stake, except when in case of accident or misplay the enemy of the party in fault decide otherwise.
CHAPTER V
HINTS TO BEGINNERS
1. Leave your ball as far from your enemy and as near your friend as possible.
2. If you are in advance, help your friend; if you are behind, call upon him to help you.
3. Recollect that position directly under the arch of your proper bridge enables you to command all the field in front of it. You can run the bridge and leave your own ball near any other you wish to croquet, as the run gives you another shot. It is many times advantageous to decline making any stroke from such position, and wait until you see an opportunity to do execution among the enemy.
