I used to grind 1$ for a couple of weeks, 4 handed version with a bounty structure. I had a couple of 75$ winnings by ending up in 3rd place (i can't really recall what was the entire prize pool because it was over a year ago ). But the reason why i stop playing it is even besides some decent wins i had there i ended up short for like 50 buyins. I like the game, it's fast and dynamic but i don't like to be down that much after a couple of weeks playing
Personally, i wouldn't recommend that game for grinding, it's more for trying your luck and hoping to hit a huge multiplier from time to time. Same goes for spin n go at Stars and Blast at
888.
