Your guide to Kakurasu

The board gives you the information needed for the next action. Mark cells so every weighted row total and column total matches its clue. The game area remains available above the explanation. 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.

A small practice goal

Keep the goal in view while choosing a move. 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.

Aim for this result

Take a moment to check the current turn. Mark cells so every weighted row total and column total matches its clue. Keep the goal in mind before your next move.

Start here and follow along

  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.

Making selections and moves

Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board.

A closer look at one example

A careful first move helps you understand the round. 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.

Notice this detail

Begin with the basic rule, then follow the result of your 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.
