Yes it is 97% RTP and exactly the same math with nothing changed

Santa 9k Yeti is a highly volatile game!

The only difference is the Yeti is wearing a Santa Hat and it is snowing in the game background, nothing else has been changed.

The name comes from three things, the height of Mount Everest and the maximum win in the game of over 9,000 x your bet. In this version, the Yeti is also wearing a Santa hat!

BIG REEL PORTRAIT MODE™ is 4ThePlayers innovation that uses up to 70% of the mobile portrait screen compared to the normal 20% a slot uses in portrait mode. This is done by stacking the reels on top of each other and spinning them right to left.

No, it's the original game just with the Santa hat enabled inside it, the hat has always been there in the original game, just only enabled for the festive period.
