The Kakurasu playbook
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. 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.
Practice with a purpose
A careful first move helps you understand the round. 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.
What counts as success

- Match all rows and columns to complete the puzzle. Each generated puzzle is checked to have one solution.
Making selections and moves
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. The game area remains available above the explanation.
Follow the example
Begin with the basic rule, then follow the result of your 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. Try the rule on the board, then read the next instruction.
A mistake to avoid
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. The game area remains available above the explanation.
