Dark Forest Chess Variant

Rules Changes

No promotions.

Each piece is a cube: King on one face, another chess piece opposite. Other sides are blank decoys.

You move/capture as the face-up piece using standard chess rules.

Tilt a piece N/S/E/W by dragging it in that direction (no diagonal tilting). Tilts can't capture, but can be used to stack onto any piece — even enemies.

When stacked, you may make normal chess moves, tilt, or move downward to the ground. You can't capture pieces that are part of a stack from the base level, and pieces with others stacked on top of them can't move.

The Dark Forest

Alien civilizations lurk in shadows cast by piece stacks. As stacks grow taller, shadows deepen and hostile aliens emerge. They move randomly around the board each turn, but only appear in spaces that are in shadow. When an alien appears in a tile fully covered by shadow, it strikes — capturing a random adjacent piece. If this captures a King, the opposite side wins.

No check. Checkmate occurs when ANY King is captured.

If a player has no legal moves on their turn, their opponent wins.

Controls
