Rough math and weak hits

That 93.13% RTP is a killer. The mechanics for the reel respins seem okay, but the actual payout frequency is terrible for this volatility. Hard to get any decent returns here.

Lacks any real momentum

This session was a major letdown. Even with those shiny graphics, the gameplay isn't entertaining at all. It lacks momentum and the vibe feels off. Definitely not worth the time.
