I have played so many Spin & Go tournaments and I liked so much. But, it is not good to my bankroll 'cause I ALWAYS increase the buy-in when I start winning often
I haven't played on pokerstars but I have played the jackpot sngs on ACR and it's nice when you are short on time to get a quick game in. It's risky but I've stayed in the plus on them.
Spin&Go are fun for if the payout is high. Most of the time, if the payout is double the buy in, players seem to be more aggressive, like all in with any Ace, and much more conservative when the payout is much higher then the buy in.
i've been playing lots of .25c spin and go lately and winning quite regularly.... i always thought it was gambling, but if you play patiently aggressive you can do well
