About
Chess, but somebody replaced the whole army with knights.
Each side gets a king and eight knights. No pawns. No bishops, rooks, or queens. Just sixteen L-shaped jumps per side and one king to protect.
It sounds like a joke until you play it. Every piece can leap over anything, so there are no pawn walls to hide behind and no open files to control. Threats arrive from squares you were not looking at. Defending means counting jumps, not holding lines.
HOW IT PLAYS
White moves first. Knights move in an L and capture by landing on an enemy piece. Kings step one square and may never move into check. Checkmate wins. Stalemate is a draw, and so is a board where neither side has enough left to force mate.
THREE WAYS TO SIT DOWN
Pass and play on a single device, with the board flipping between turns.
Find an opponent and get matched with whoever else is queuing.
Create a room, share the six-character code, and sit a friend anywhere.
BUILT TO BE QUICK
Games are short. The board is legible at a glance: legal moves show as dots, captures ring the piece you would take, and the last move stays lit so you can follow an opponent who moved while you were away.
