The tutorial is confusing because it explains some mechanics in a way that makes them feel daunting when it's easy to understand them after a few games, and it doesn't explain other parts like the classes or the bonuses and what they do, so when you start your first game after the tutorial you feel lost again.
The gameplay definitely has potential, I just couldn't really get invested in it enough to continue playing after a few games. The score multiplier is quite small so it's hard to get a sense of how much you're earning per ball, and the roulette itself doesn't give enough time to actually register what's happened before the round's over imo. The different ball types are cool and the play vs. bet mechanic is a fun challenge, but I probably won't keep playing it unfortunately
