Players move, and must move, in turn. White moves first. Entering the shadowpiece . Moving a piece. Capturing one or more men.
Capture is obligatory and has precedence in both phases.
A player captures the top man of an opponent's piece on an adjacent square, by jumping the piece with is own piece, taking the top man along under it, and landing on the square beyond, which must exist and be vacant for the capture to take place. If there's more than one way to meet this criterion, the player is free to choose. The capture of a single man reduces the number of pieces on the board by one. Since there is no mechanism to increase the number of pieces, a game of Emergo is always 'spiraling upward', that is, the number of pieces steadily decreases while their size increases. The next sequence is only to illustrate mechanics.
