There are four ways to make captures:
1. Displacement - enemy pieces that are not of the same "family" are simply removed from the board, as in FIDE and most other traditional varieties of Chess.
2. Assimilation - a piece may capture both friends and foes of the same "family" and assimilate their powers. The Rook (a sliding piece) may merge with a Ringmaster (also a slider) to form a Princess. It may not merge with, say, a Knight, because the Knight is not a slider.
Note that compound pieces formed this way may be split apart later. In the Zillions implementation, to break a Princess down into its components, simply click your mouse on the cell where you want the Rook-part or the Ringmaster-part to go. That part will move, leaving the other part behind. Fergus Duniho first popularized this method of capture in some of his games in the early 2000s.
3. Conversion - a leaping piece (Knight, Archer, Airman, Sailor, or any compound thereof) may convert an enemy piece to a friendly piece simply by flying over it and landing on the cell beyond. N.B. If the cell beyond is also occupied by an enemy piece, a leaper may make two captures simultaneously. For example, a Knight flying over an enemy Rook and landing on top of an enemy Spire would convert the former and kill the latter, in one move. An Archer flying over an enemy Ringmaster and landing on top of a Knight (either friend or foe) would simultaneously convert the Ringmaster and assimilate the Knight.
4. Sandwiching - Pawns and Guards also convert enemy pieces to friendly pieces, by "sandwiching." An enemy Knight caught between two friendly Pawns, for example, is converted to a friendly Knight. On rare occasions, Pawns and Guards may be able to capture two pieces simultaneously.
There are three ways to win:
2. Stalemate - I would like to make this better than a draw, but not quite as good as a checkmate. In tournaments, FIDE awards one point for a checkmate and a half-point to each player for a draw, with stalemate counting as a draw. For this game (and any others that I invent), I would award a half-point for a stalemate - but only to the player forcing the stalemate. I cannot implement this in the Zillions programme, as it does not differentiate between superior and inferior wins, so for the Zillions programme, a stalemate is a win.
3. Converson of the King - given that leaping pieces convert enemy pieces by flying over them, and that Pawns and Guards also convert enemy pieces by sandwiching, it is possible for the King to be converted to an enemy piece (this actually happened once while playtesting this game with Zillions). The player whose King defects to the enemy, of course, loses the game.
