[Game overview]
・This game is a game where you fit three randomly generated puzzle pieces into the frame of the board to form lines and earn scores.

- If you place all the generated puzzle pieces, a new puzzle piece will be generated.

-You can stock (save) up to one generated puzzle piece and arrange it on the board at any time.

- When you fit the pieces into the frame on the board and form a row, the pieces in the row will disappear and you will be able to place the puzzle pieces again.

・When there is no place to fit a puzzle piece into the frame on the board, if the stock frame is empty, you can stock the puzzle piece.

- If there are no more places to fit the puzzle pieces, including the stock frames, into the frame on the board, the game will be over.
