    Back to Temp

[Rule]

Put a black circle or a white circle in every white square (where both small black and white circles are shown) to avoid 3 adjacent same color circles horizontally, vertically, or diagonally.

(This puzzle rule is designed by Erich Friedman.)

[Operation]

  1. Left click -> Fix the stone color, Right click -> Back to the unfixed status
  2. If "Temp" is pushed, you can mark the stone the "temp" status(indigo color).
  3. "Back" -> 1 step back, "Restart" -> Restart from the scratch, "Save" -> Save the current board, "Restore" -> Restore the saved data.
  4. You will win when you put stones on all the white squares according to the rule.
