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.
When spin stops at the skull you lose your winnings, more than half... after a few skulls everything you won goes down the drain. We have the option to collect or partially collect our winnings, but then we lose chances to get some higher payouts. I know a few people who won the "Actionspin", but I never got there... probably because I'm too aggressive player and I raise the stakes after some losses which often puts me in very unfavorable situations. It's either "collect" and save some money or get totally busted.
One of the craziest games definitely... It makes us play more and chase that "Actionspin", but that skull can appear anytime and wipe out all of our effort just like that. I am playing it for years and I still have the same excitement whenever I play it.
