The purpose of your moves

Take a moment to check the current turn. Mark cells so every weighted row total and column total matches its clue. Try the rule on the board, then read the next instruction.

The steps to play

  1. A 5×5 grid shows target sums at the right and bottom.
  2. A marked cell contributes its column number to its row sum, and its row number to its column sum.
  3. Tap cells to mark or clear them. Current totals are displayed alongside the target totals.
  4. Match all rows and columns to complete the puzzle. Each generated puzzle is checked to have one solution.

Controls

Read the position before choosing your next action. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. Keep the goal in mind before your next move.

Put the rules into context

The board gives you the information needed for the next action. 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.

One detail worth checking

Read the position before choosing your next action. 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.
