Seal The Ghosts

Seal The Ghosts is an action game using some paper cups with a colored seal.
The goal of the game is to seal as many ghosts as possible and to minimize ghosts in your hand when the game is over."Ghost" is a paper cup, and "Seal" means to put the cup inside of "Ring for Sealing". You can put "Ghost" on the other ghost, but if you want to do it, there must be at least one ghost of the same color under it to be placed on top of it.
The player who sealed all his hand-held ghosts is not the winner, and the one who broke the sealed ghosts is not the loser, but the player who has less ghost in hand at the end of the game is the winner.
