· After starting, touching either beginner (color matching) or advanced (letter matching) will start the game.
· In the case of beginner (color matching), if you manipulate the falling block and make the "same color block" adjacent to 4 or more (either vertically or horizontally), it disappears and the score enters.
· In the case of advanced (letter matching), the operation is the same as the beginner, but by extinguishing "the same character block" instead of the same color as in the beginner class, it disappears and the score goes in.
※ Block color is meaningless for advanced (letter matching).
· If you stack up to the top, the game will be over and the game will continue until the game is over.
