Kakurasu: a guide for your next round
Use the controls beside the game rather than guessing the rules. Mark cells so every weighted row total and column total matches its clue. Try the rule on the board, then read the next instruction. A 5×5 grid shows target sums at the right and bottom. Keep the goal in mind before your next move.
Generated 5×5 puzzles with an exact row-mask search for uniqueness before publication to the board. No calibrated difficulty labels.
One thing to notice as you play
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.
The goal to keep in mind
A careful first move helps you understand the round. 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 playing sequence
- 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.
Keyboard and screen 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. Try the rule on the board, then read the next instruction.
Work through an example
Take a moment to check the current turn. 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.
A common point of confusion
The example and rules describe the same game you can play above. The value is the position in the row or column, not a uniform count of marked squares. Try the rule on the board, then read the next instruction.
