合計数字の1の位が9に近いほど強いあの「おいちょかぶ」です。 シッピン、クッピンなどの有名な役に加え、トイチ、ノボリなどマイナーなローカル役もたくさんあります(オプション設定可能)。 札は花札と株札を選択可能です。勝ちやすいように場札を一度配り直し可能なゲームモードもあります。 このアプリ1本で、おいちょかぶはとことん楽しめると思います! また、2020年10月のアップデートによる「かちかち(じゅんじゅんとも呼ばれる)」も遊べるようになりました。 「かちかち」とは「おいちょかぶ」のように札二枚の合計が9に近い方が勝つゲームですが、ベットの仕方がポーカーのように親から順に行う点が違います。 また、役も「おいちょかぶ」とは異なります。「おいちょかぶ」同様勝ちやすい「かちかちイカサマ」のゲームモードもあります。 ハッタリが醍醐味の一つのゲームですが、このゲームのかちかちではAIもハッタリを使ったり予想したりします。

Koi-Koi (Japanese: こいこい) is a popular card game in Japan played with Hanafuda cards which is one of ways to play Hanafuda(Japanese playing cards) with two players. The goal of the game is to make the combination of severalcards earlier than your opponent. The phrase "koi-koi" means "come on" in Japanese which is said when the player wants to continue the hand. The object of the game is to form special card combinations called "yaku" from cards accumulated in a point pile. Players can gain cards in their point piles by matching cards in their hands, or drawn from the draw pile, with cards on the table. Once a yaku has been made, a player can stop to cash in points, or keep going (referred to as "koi-koi", hence the name of the game) to form additional yaku for more points. The point values assigned to individual cards have no effect on the score, but they are helpful to judge their value in forming yaku.

ReceptionRating · Positive reviews · Number of ratings

モバイルおいちょかぶ holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Hanafuda・Koi Koi has 559 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of モバイルおいちょかぶ's written reviews are positive against 56% of Hanafuda・Koi Koi's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

モバイルおいちょかぶ ships an update every 18 months, Hanafuda・Koi Koi every 5 weeks. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
