Quite the bad clone of UNO in terms of UI and matchmaking honestly.

You can create lobbies but not set the password instantly to prevent other players from joining quickly, so you have to kick them and give them a bad first impression when you just wanted to create a quick game with friends. Accounts don't have passwords either oddly and the game can randomly disconnect you from matches midplay while having a stable ping. Even if you manage to reconnect to the match the damage is already done and sometimes that prevents you from creating a separate room.

Also, while playing there's at first not a clear indication fro newcomers of whose turn is it. I'd have used an arrow instead of the spinning border. Regarding when to say "Duo" and when to skip turns, the rule can be inconsistent with plays not to mention the frequent lags from the server.

I'll give it the fact that it seems to be an indie project in continuous development and with a Discord server for players not to mention the smooth and clean presentation. However, it still has these issues 2 years after launch and I haven't even mentioned the microtransactions.
