Pressing a light switches it and the lights next to it. Turn the whole board dark, level after level, on 5×5, 6×6 or 7×7 boards.
玩法
- 1Press a light to switch it and its neighbours above, below, left and right.
- 2Turn every light off to solve the level.
- 3Fewest shows the smallest number of presses that solves the level. Try to match it.
- 4Solving a level unlocks the next one. Use the arrows beside the level number to go back to earlier levels.
操作
技巧
- Pressing a light twice cancels out, and the order of presses does not matter.
- Work row by row: for each light still on, press the light directly below it. Then only the bottom row is left to sort out.
- Hint always points to a press from the shortest solution for the board as it is now.
