Player Experience Highlights
Community Insight:
We 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.
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".
