Can I ask, dude, have you seen any crypto casino games with a 100% RTP in this crypto gambling industry? The highest I've seen is 98%, though I can't remember which casino it was.
I don't know if you are aware but MetaWin has had several promotions lately where certain games where on offer with a 100% RTP. That's the case for Dragon Tower 100 right now. You can read more about it here:

Before Dragon Tower 100, MetaWin offered similar promotions for Dice and Mines.
