AI Extreme Logic Puzzle
Counts. Areas. Connections.
Eight demanding boards
All eight 8×8 puzzles, including Stage 1, use demanding selection criteria. Each original puzzle has exactly one independently verified black-and-white solution. Human difficulty and solving time vary. Any stage can be selected; there is no deadline.
Counts, islands and connection
Row and column numbers count black cells. Each side-connected white island must contain exactly one numbered cell and have exactly that area, including the number. All black cells must connect through sides. Diagonal contact does not connect cells. Black 2×2 blocks are allowed.
A visual walkthrough
Home → Visual walkthrough teaches the rules on a separate 4×4 board with pause, replay, wrong/correct examples and two practice cells. This never changes your actual game progress. Full written rules are available from its book button.
Try a hypothesis
Choose a color, then tap a cell. Hypothesis saves your original board, notes and undo history; Discard restores them and Commit makes the whole attempt one undoable move. Question-mark notes, 100 undo steps and an enlarged board help you reason.
Checks and answers
Check shows immediate contradictions, not a guarantee that a partial board can be completed. Settings → Reveal answer requires confirmation and is marked separately from an independent clear. Restart resets only the current stage after confirmation.
