カエルの王冠 (Kaeru No Ōkan)

It is a "must follow" game with no trump suit. The game consists of 36 cards (1 to 9 in four suits), and 9 scoring cards. Each of the scoring cards show two lily pads, side by side, with a variable amount of victory points: sometimes positive, sometimes negative, and sometimes 0.

They will score the right most value on the card, and their left hand neighbor will score the left most value. The most score cards that can be placed between two players is 3, and if a 4th would be added, it is instead moved clockwise to the next position between players that does not already have 3 score cards. The game lasts 1 hand. Each player sums the right half of the scoring cards on their left and the left half of the scoring cards on their right. The player with the most points wins.
