Spotting Subtle Color Differences ~ “Iro Kankan 2” is a revised edition of the long-running bestseller “Iro Kankan.” Since the gameplay has gradually evolved from the original “Iro Kankan,” we’ve named this version “Iro Kankan 2.”
This is a game where players spot cards with slightly different colors. There are 41 cards in total. The numbers range from 0 to 20 in both the green and red directions, centered on 0.
There are several ways to play. Here are a few examples.

❶親の宣言 一覧カードを参考に、自分の手札の色から「この色は○番くらい」と思う数字を宣言して、裏のまま場に出します。※1枚の数字、または2枚の合計でもOK
❷勝負 or パス 他のプレイヤーは親の宣言より近いと思えば「勝負！」と言ってカードを1枚（または2枚）裏向きで出します。出さずに降り（パス）ることもできます。
❸公開・得点 全員同時にカードを公開。宣言数字に最も近い人が場のカードをすべて獲得。同点の場合は、同点者同士で再勝負。親を時計回りに交代して❶から繰り返す。誰かの手札がなくなったら終了。獲得カードが最も多い人の勝ち！
The sum is 20
The person who chooses two cards that add up to a number closest to 20 scores points.
