Fog Chess
You only see what your pieces can see.
Squares not currently defended or attacked by one of your pieces are hidden in fog. Scout carefully — moving blind is part of the challenge.
Rules
Read before you play — no surprises mid-game.
- A square is visible if one of your pieces legally attacks or occupies it.
- Hidden squares show fog instead of the opponent's piece, if any.
- The engine still enforces full legality — you simply cannot see everything before you move.
