X Men‘s Morris rules apply

To Win

Leave your opponent with less than 3 men, or without any possibility to play his turn.

To Play

Each time you align 3 of your men, you can remove one of your opponent's men from the game.

X represents the number of pieces (=men) you start with.

There are two phases in the game:

Fly Variants

I you are playing one of the "fly" variants, you can move a men to any available position (not only adjacent ones) when you are reduced to 3 men.

The "fly" variants differ on a second point, which is easy to miss: a man that stands in a mill can be removed there, where the standard variants protect it.
