How to Play
Objective
Fill every hex cell with a number so that each row satisfies its constraint label. Complete all rows to win!
Controls
- Click a cell to cycle its value (1 → 2 → … → 6 → clear)
- Right-click a cell to cycle its value down (6 → 5 → … → 1 → clear)
- Restart button resets the puzzle to a blank state
Constraint Types
Σ Sum — cells in the row must add up to the target
Π Product — cells must multiply together to equal the target
≥ At least — the row sum must be ≥ the target
≤ At most — the row sum must be ≤ the target
Special Cells
×2Double — its value counts twice in every row it belongs to
2|4Split — shows two options; click to toggle between them
∅Void — excluded from all rows; splits a row into two segments
Example
Three cells in a row with a Σ 6 sum constraint:
Labels sit just outside their row. Hover a cell or label to highlight its row in the game.
