You can play different games with these Hwatu cards: Go Stop, Min-Hwatu, Matgo or even Hanafuda.
The Go-Stop game can be played with 2 or 3 active players. If there are more than three players, they wait for their chance to play in the next deal and can be compensated. When only two players play, it is called Matgo (맞고 in Korean). The main objective of all these games is to capture cards in the central layout by matching cards that belong to the same month (flower) while scoring points for combinations between these cards.
