Simlis

Tower looks the part as a crypto casino but my experience was middling. deposited btc fine, played, won a bit, then went to withdraw around 220 and it sat on pending confirmations far longer than any other crypto site I've used, the best part of a day for something that should be near instant on chain. it did arrive eventually. the bigger issue is the game range is pretty thin, not many providers, so once the novelty wore off there wasn't much to do. not a scam, just slow and a bit bare for a crypto site in this day and age, two stars

Free spins are limited, but the deposit match is generous. Overall a decent bonus for slot players.
