### 3/5 — 良作

*2025-02-01*

これまでの累計対戦数が12の倍数になっていないのが変だとは思います。

### 5/5 — All-time Classic

*2024-01-25*

I can't believe this app is still going strong, since 2001!

### 1/5 — ゴミ

*2021-05-10*

ここまでプレイヤーをおちょくってるアプリは近年稀にみる超絶ゴミアプリな笑

### 1/5 — Disappointing

*2020-10-17*

You can’t turn off the hints so it’s not much of a challenge to play. Waste of £1.99

### 2/5 — Not like it's Google counterpart

*2019-09-17*

I thought this was the iPhone version of a popular Google Play version that looks very similar. It's not. There are almost no controls. The game makes playable cards from your hand flash in a very annoying way and there's no way to turn it off.

### 1/5 — Very poor Implementation

*2017-06-12*

There is at least one scoring bug: does not double player score when over seven points but does double computer score 3hen over seven points.
The options should be "Koi-Koi" and "Stop" not "continue" and "finish game"
There game speed should alter the momentary pause when a card is played to the table not the speed at which cards fly from the deck.
The _suggested play_ flashing is too intense and is distracting.
Game does not display the point count when offering 
'Stop or continue"
A game consists of 12 hands not "12 games"

### 1/5 — 動作が滅茶苦茶

*2014-07-11*

こちらで取った札が相手方に行ってしまったり、全くひどい。
このままじゃゲームとして成り立たない。

### 1/5 — 購入する価値なし。

*2013-09-20*

全く自分の好きなように設定できない。すぐ捨てた。

### 1/5 — 楽しめない

*2013-09-01*

めくりのスピードが早すぎて勝負を楽しむ雰囲気ゼロ。
札のサイズも小さすぎる。良いとこなし！

### 4/5 — 良作

*2013-04-03*

操作性が良い。値段分の価値は十二分にある。

自分が出せる札、取れる札が明滅するためとてもわかりやすい。

ゲームセンター機能がいらない場合、オプションで機能をオフにし、再起動すればいちいち「おかえりなさい」と言われずにすむ。

要望

札の移動スピードがかなり速く、自分が山から何を引いたか、場の札を取れたか、相手が何を出し、何を取ったのかが一目ではわからない(動体視力の問題かもしれないが)ため、オプションで移動スピードを変えられるように

役が出来た時の選択肢を
こいこい or 終わる だと味気ないので
こいこい or 勝負 に
