6561 Base-3 is played on a 9×9 board where tiles are powers of 3 (3, 9, 27, 81 …) and three matching tiles merge instead of two — so 3 + 3 + 3 = 9. Create the 6561 tile to win. Each move you swipe or press an arrow key, every tile slides in that direction; if anything actually moves, one new tile appears. The corner-anchoring and monotonic-ordering strategies from 2048 still apply, and 81 squares give you more room to manoeuvre, but lining up three-of-a-kind makes chains harder to set up. When no move is possible in any direction, the game is over. Your game and Best score are saved in your browser automatically.
