Ultimate Tic-Tac-Toe, rebuilt as a real strategy game for two to four players.
Tic-tac-toe is solved, so it has no depth for repeat play.
An expanded Ultimate Tic-Tac-Toe on a 27×27 board, for two to four players online or on one device, with eleven special moves that can change the board. The winner is the player with the most points: one for each board claimed, plus three for each fully claimed line of boards.
Casual and competitive players looking for a fast, replayable strategy game.
A Flutter client and an authoritative Fastify server over Socket.io, so every player sees the same match.
A Flutter and Riverpod client with a Fastify, Prisma and PostgreSQL backend. Matches run in server-authoritative rooms over Socket.io. The rule engine is split into separate handlers for movement, tactical moves and scoring, with an opening book for the two-player AI.
Built as a mobile-first app locked to portrait on phones and tablets. Rooms recover from dropped connections with a 90-second grace period and one-tap rejoin after an app restart, private lobbies expire after 90 seconds, and the AI has to pass hard quality gates. ECHO draws its constellation film on the GPU and composes a song from the recorded moves; CANVAS makes a repeatable wallpaper from the final board.
