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?
