Real chess with real teeth, duel the computer on a classic board, or survive a four-player melee where three opponents close in at once.

How to play
Chesseract plays full-rules chess. Develop your pieces, control the centre, and deliver checkmate by trapping the enemy king. The four-player board scales the same ideas up to a chaotic crown grab where alliances and timing decide everything.
Classic mode: standard 8x8 chess with castling, en passant and pawn promotion.
Checkmate the opposing king to win; stalemate draws as usual.
Four-player free-for-all rewards captures and mates with points; teams pit two pairs against each other.
Promote pawns through a piece-picker, and undo a slip with one take-back per turn.
Controls
Desktop: click a piece to select it, then click its destination; use the on-screen buttons to flip the board, undo or resign.
Phone & tablet: the classic board is built for mouse and click input, so a desktop or laptop is recommended for the smoothest play.
Game modes
Play vs AI: choose easy, medium or hard, set a time control, and even pick the opening the engine answers with.
Pass & play: two people share one device on the classic board, or four on the multi-player board.
Play online: create an invite, join with a code, or jump into a quick match against another person.
Four-player: face three AI rivals, watch the engines battle, or seat four humans, in free-for-all, teams or last-king-standing survival.
Tips & strategy
Castle early to tuck your king away before the board opens up.
Against the AI's opening choices, study its first few moves, knowing the line lets you prepare a sharp counter.
In four-player, avoid overextending: the player who attacks first often gets ganged up on by the other two.
Trade down to a winning endgame rather than chasing flashy sacrifices that leave you exposed.
