Quite a bit of thought has gone into designing the turtles, equipment, etc. and a lot of it has been shaped by player feedback over the months. So all of you are very much part of the reason Serenitrove is what it is today. Thanks so much!
As for the jackpot turtle, he's more of a fun pick than a game-changer, but I personally love his hat. To unlock him, you'll want to stock up on Quartz. There's actually a hidden "pity" mechanic in place. If you spin the slots multiple times in a single session (without closing or refreshing your browser), your chances of landing the jackpot will gradually increase. So if you're aiming for him, try to do it all in one go, but expect to spend hundreds of Quartz.
Glad to hear you liked Scoot's Theme, it's one of my favorites too. I think it captures his carefree personality pretty well :)
