I usually just play when I get free spins or something like that. So the answer may be everyday 10 spins (or 20, sometimes) of R$0.10 because of a daily promotion of a sports bet site that I have an account.
I play most days for a few minutes here and there, mainly free games. I might do martindale strategy at micro stakes for four bets If I've built up a nice pot of money.
Not very often for me. Poker is still my main game, and I might play casino games occasionally when I’m in the mood for something different. I’d say maybe once or twice a month, usually with a small amount.
