I played spin and go at Poker Stars - 1 and 3 dollar games. Won 7 out of 10 with a sensible and cautious approach. Then I lost 24 out of 25 games with same stakes and same approach. No tilting, just bad luck or what?
You've only played 35 games, you're not even close to having a big enough sample size to define a win rate or anything like that. One thing worries me about your post.... You worry about luck. The more you concentrate on luck, the less likely you will be to see the game for what it really is. One hand at a time. Make the best decision you possible can every time it's on you to act and you'll be a winning player.
I feel many people post something like this because they're upset they lost money in they're session. Don't do that, there are always swings in poker....
One other thing, you asked if it's a "rigged game".... In no way shape or form are you questioning your own play anywhere in this post. What if you didn't play very well and that's why you're not winning as much as you like? You can't tell me you played every spot perfect. Get rid of your ego, study as much as you can, and just play. If you do that, maybe you have a chance at making good money at this game.
I'm gonna be honest with you, just by the way you spoke in your original post I can tell you will never make money if you continue to think the way you do now.
So in total you played 35 games and won 8 of them . thats just normal variance ... Spin and Gos are High Variance so 35 games is no sample size , I play alot HU Hyper Turbo Sngs with a ROI of 2% . and it s totaly normal that you lose 20 games in a row . If you compare Spin & Go s to Hyper HU Sngs , it s much more likely to lose 20games in a row by playing Spin &Go s . Thats why you should use a BRM of 500Buyins+ for playing Spin and Go s . GL at the tables.
