Game guide · LIER88

Read before your next round of Kakurasu

Read the position before choosing your next action. Mark cells so every weighted row total and column total matches its clue. 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.

A small practice goal

Begin with the basic rule, then follow the result of your action. 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 the game asks you to do

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.

Making your moves

  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.

The controls to know

Check the rule below as you play. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. Start a new round when you are ready to try again.

An example to follow

Read the position before choosing your next 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. The game area remains available above the explanation.

Notice this detail

Check the rule below as you play. The value is the position in the row or column, not a uniform count of marked squares.
