Hi @Adunsmoor welcome to our community - In the new Octopus version of Mystery Mountain you have only a chance to win Gold Bars every time you are rewarded, but you don't win that every time.
Meaning, you have only the possibility to win Gold Bars in the Octopus version. If your win Boosters, Pet Coins, Unlimited Lives or Gold Bars is randomly chosen when you win. You never know what is given.
Mystery Mountain is the only feature where you can win Gold Bars at this moment in the game, but you can also use the Pet Coins for Boosters or Lives in the game.
I did get them with the Octopus version, and I did NOT use them to buy lives etc. one night I had 13 went to bed and next morning there were only 6 . Last night had 6 and this morning only one. My phone is off during the night. This is very frustrating. And I CANNOT find any updates for the next level 2968. This is very frustrating and also for the team
