About the game
Rule the board like a castle strategist in Walldoku — a logic puzzle from the Sudoku family, wrapped in a sober medieval world of stone walls and corner towers.
Every board is divided by walls into sections. Each straight run of cells between walls must hold the numbers 1 up to its length, with no repeats — a run of three holds 1, 2, 3; a run of five holds 1 through 5. Read the walls, deduce what fits, and complete every castle.
Start in a tiny 3×3 keep and work your way up through ever larger fortresses, all the way to sprawling 10×10 strongholds — plus premium 12×12, 15×15 and 20×20 castles for true masters.
