Kakurasu: instructions and practice
Use the controls beside the game rather than guessing the rules. 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.
Generated 5×5 puzzles with an exact row-mask search for uniqueness before publication to the board. No calibrated difficulty labels.
An idea for your next attempt
Use the controls beside the game rather than guessing the rules. Tap cells to mark or clear them. Current totals are displayed alongside the target totals. Keep the goal in mind before your next move.
What counts as success
Keep the goal in view while choosing a move. Mark cells so every weighted row total and column total matches its clue.
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.
Controls
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. Keep the goal in mind before your next move.
See how the rules apply
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. The game area remains available above the explanation.
A common point of confusion
Keep the goal in view while choosing a move. 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.
