Wow, I used the "Dinos" bonus which provides 20 free spins on the Digging For Dinosaurs slot, and out of those 20 spins, only 1 hit. That one hit awarded me a feature though, which provided 10 free spins.... Then, out of those 10 spins, not a single one hit. So out of 30 spins, only one paid, and it paid very little. I've had my fair share of slumps, but that has to be a record for me. Don't anyone even waste your time with the ndb, let alone deposit.
