Let's play the traditional Japanese card game Hanakoi.
Koikoi is one of the competitions of Hanafuda where two people play. The hand type (same month, plant) and the place tag type are combined and used as their own cards. It is a game of competing for the score that you get.
You can choose a 6 or 12 month battle with the usual simple rules.
There are beginner and advanced levels, and you can enjoy beginners to advanced players.
