From the start of a round
- A 5×5 grid shows target sums at the right and bottom.
- A marked cell contributes its column number to its row sum, and its row number to its column sum.
- Tap cells to mark or clear them. Current totals are displayed alongside the target totals.
- Match all rows and columns to complete the puzzle. Each generated puzzle is checked to have one solution.
Input guidance
A careful first move helps you understand the round. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board.
Learn from a sample situation
The example and rules describe the same game you can play above. Marking columns 2 and 5 in the same row gives that row a total of 7. A mark in row 3 contributes 3 to its column. Try the rule on the board, then read the next instruction.
Check this before moving on
Take a moment to check the current turn. The value is the position in the row or column, not a uniform count of marked squares. Start a new round when you are ready to try again.
