The Kakurasu playbook
Read the position before choosing your next action. Mark cells so every weighted row total and column total matches its clue. Start a new round when you are ready to try again. A 5×5 grid shows target sums at the right and bottom. Try the rule on the board, then read the next instruction.
Generated 5×5 puzzles with an exact row-mask search for uniqueness before publication to the board. No calibrated difficulty labels.
Something to practise
Take a moment to check the current turn. Tap cells to mark or clear them. Current totals are displayed alongside the target totals. Try the rule on the board, then read the next instruction.
The challenge in front of you
Check the rule below as you play. Mark cells so every weighted row total and column total matches its clue. Keep the goal in mind before your next move.
How to proceed
- 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.
How to interact with the game
Begin with the basic rule, then follow the result of your action. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board.
Try this example
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. Keep the goal in mind before your next move.
Avoid this misunderstanding
The board gives you the information needed for the next action. The value is the position in the row or column, not a uniform count of marked squares. Keep the goal in mind before your next move.
