How to play

  1. Tap any tile to flip it and its neighbours.
  2. Flipping is contagious — edges and corners touch fewer tiles.
  3. Turn every tile green to win.
One good tipSolve it row by row. Once the top row is green, the tiles that fix the second row are forced, and so on down the board.

Questions

Is every board solvable?

Yes. Each day's board is generated by applying taps to a solved board, so a solution always exists.

Does tap order matter?

No. Flipping is its own inverse, so only the set of tiles you tap matters, not the order.
