Not very good. Game lacks any features beyond basic. Graphics look very dated and unsophisticated. Adverts load in a split second, (every time you switch over to the game). The moves of your opponent can take 2 - 5 minutes to actually appear on your screen. You get the notification your opponent's made a move, you switch to the game, then you have to wait minutes (wifi or 5G don't make a difference) It's painful to play it's so slow. Adverts are quick as hell though... Thumbs down from me.
