Buggy.
Example 1: Sometimes the totals of the other players are incorrect and you must add the card values yourself to ensure the total is right. This is usually obvious (eg 2 is the displayed total when it should add to 27).
Example 2: Randomly after several days playing without this issue, now even when killing and restarting the app, when playing against AI it seems the AI is taking my turns in an alternating fashion (in addition to theirs). E.g., I pick first card, pass the group, then a card is automatically picked for the next group, then I am allowed to pick the next card, etc. unplayable when in this state.
Example 3: some achievement text is too long to display within boxes and gets cut off.
Example 4: cards are displayed in a way that makes it just barely impossible to see their value, so you must touch almost every card to see what it is instead of viewing your hand as a whole.
Example 5: if you take more than 5 seconds to select a card, this character annoyingly covers half the screen reminding you to select a card. Even if dismissed he returns in 5 seconds.
