Hmmm, well obviously it’s all due to luck. But picking the game can make a huge difference. I think from playngo games my biggest win ever has been something like 1200x (Moon princess 100). I think that playngo is a very good provider but not the one where you can experience these HUGE wins. 

Try out some hacksaws next time. Use lower bets, and try out some scatter boosts to land 4 or 5 scatter bonuses.
