Topidoku is a daily word-based Sudoku puzzle game. Instead of numbers, every row and column forms real, valid words from selected topics like Arts, Films, Science, Sports, and Technology. Within each topic a player can optionally drill down to a specific sub-topic. Solve daily challenges or play unlimited casual games across multiple grid sizes (from quick 4×4 puzzles to challenging 7×7 master grids). Free to play directly in any browser with no download and no account required to start. Features daily streaks, community leaderboards with county flags and scores / stats, and spoiler-safe emoji result sharing.
