I used to like Playngo the most back in the old days, like 2018-2020. After hitting maxwin in Reactoonz I kind of wanted to play only Playngo games…
When bonus buys got more common, especially in the new Megaways games, I transitioned to those. Also the maxwins were completely different, you could hit over 10.000x and that got me excited. Back then it was Blueprint and BTG mostly who did these games, but later also No Limit and many other providers hopped on.
I kind of miss the old days when you could only get the bonus / Free spins by playing normal rounds. The games were not so fast paced and you could enjoy the slots in a different way.
it also seems that people want to play super high volatility games now while chasing huge wins like 30k x or even bigger. However, Novomatics for example are a good option if you like a bit more stable volatility.
