You ain't gonna find the answer from slot icons. You have to open the slots individually and check all columns...
Thank you for this short but priceless explanation because it is not easy to understand the rules, especially for the first-timer.
...not his fault...Hhampuz has turned on his FBI mode
Of course, not his fault and I am not suggesting that, additionally, it looks like Mission Impossible mode for me
.
PS
Still can't find the right slot and encountered even more problems because here where I live casinos are limited and many from these slots (50%) are not available in my region, so I can't see the rails.
Of course, I could use Proxy or VPN, but already it took quite some time to load slots and with additional addon or program, it would be so long that it could kill the hall fun.
So, I have to skip this challenge, but I want to wish luck to all remaining and active participants. Great promotion Roobet and as always great work done by Hhampuz!!!
