I got the prize, and Cave of Plunder ate most of this prize (and the deposit before that). I still think this is one of the craziest games in the crypto gambling space.
I just made deposit after reading through your post and tried out the game and it was indeed crazy.
The part I love most about it is the fact that your multipliers still remain even if you don't get the next one correct (although you lose your money for that spin) and you don't even have to start all over again after your spin stops at the skull.
I tried so many times but in the end I lost all my deposit there but at least Ive an experience in the game - and I'll still visit the game when next I make a deposit.
