Glaring deficiencies
1- there’s no documentation anywhere on how the game works, the scoring, how much time does one have per turn, how many free plays, how does one climb the leader board, etc, there is in fact no documentation whatsoever.
2- some app bugs. E.g. the app sometimes accepts me into a tournament but then doesn’t actually seat me or deal me cards. If I refresh, app says I already my used free tournament and next one available is in a few hours. Also, it sometimes refuses to register a play and then places the cards in default positions instead. This may be an internet connectivity problem, not sure.
