Yes it can be. Now I lost more money as I won but you can get easy cash. There is a high luck factor because of short stack, fast increase of blind levels and only 3 Players on table. In the 25ct Spin and Gos there are many gamblers so if you get a good hand you can kick them easily out. And if youre very lucky you get into Spin and Gos where you can win 3x or higher of your buy in, when you win one you get good money for more tournaments. One time when I was highly on tilt I increased the buy in game for game (no safety advice!) and won 25$ in a 5$
spin and go, was lucky and got my cash back which I lost before and a little extra.
If I would compare the BLAST (888poker) and Spin and Go (which are similar) I would highly recommend the Spin and Gos. Dont know how to win the BLAST, I really dont. There is a countdown if it goes to zero everyone have to go all-in. I played like 10 games one evening and won not a single game no matter if before the countdown hits or after.
