くまモンの花札こいこい is a free game developed by Kazutaka Sato for iPhone. This game features the popular character "くまモン" from Kumamoto prefecture in Japan, and it is based on the traditional Japanese card game called "こいこい".

The game provides a guide to help players get familiar with the rules and gameplay, making it accessible for both new and experienced players. With colorful illustrations of くまモン on the cards, the game adds a fun and exciting twist to the traditional flower card game.

Just like the traditional game, players can choose to play 3, 6, or 12 rounds, and the player with the highest total score wins. For more detailed rules, players can refer to the in-game help section.

It is important to note that the game automatically saves progress, but players should avoid exiting the app or turning off the device during a save to prevent data corruption. Deleting the app will result in the loss of saved data.
