After reading your reviews and this topic in general, I thought this: it would be nice if the players would win very small amounts, but these winnings would occur as often as possible.  But of course, the balance of the interests of the casino devs and the amount allocated for winnings to the players must be observed.  Well, judge for yourself - it's one thing when you play 5-10-20 times and lose all the time.  And it’s a completely different thing when you win a little and, for example, on average 1 time out of three bets.  And there will be more emotions and mood will improve.  And you will play longer.  These are the types of games I think should be introduced more into the practice of casinos. 
And I think casino devs should think hard about games with small winnings, but occurring more often than is usually available now.
