When you place a stone, the stone and tile will be flipped together.
If you drag the stones on the right side of the screen and place them on the board, not only the stones between them but also the tiles that make up the path will be reversed according to the Reversi rule. Choose a place to put it, and change the board surface to a shape that you can pass through.
After placing everything, trace the path and answer
After placing all the stones you have, trace the path from the start to the goal. Solve one question in two stages: placing stones and confirming the completed route.
