We have 3 mini-games (Plinko, Wheely, Free Spins) and after hitting one you can win really big (bonus games return ~8% of house edge we got from base game and this verifiable with provably fair algorithm).
I visited "Bonuses" section on the website. It contains some information about Jackpot, Leaderboard, Cashback and Magic chest. But I couldn't find anything about those these mini-games.
When the gambler is eligible for Plinko, Wheely or Free Spins?
Right now we are adding this information to How to Play and Fairness sections, should be ready by end of week. Our calculator at Fairness page already include bonus games. We use 2nd (3rd for classic dice) 4 bytes of the hash to generate random event based on probabilities of bonus games. So everyone is eligible, bonus game may happen with any winning bet.
