The most adictive gambling are te progressive slots, it's basically all I play lately if I want to gamble some extra BTC money that I may have and I don't plan to hold or invest. You start with a little bit and go on a rollercoaster with ups and downs, sometimes I was up 1 BTC from 0.1 BTC but ended up with 0 because I was too greedy.
How can progressive slot is the most addictive games? That games is the easier game to stop because after you hit some winning you will sure get some profit and it can stop by itself without us to concern the result but if you playing dice you can't stop because dice games will slowly increase your balance and if you set on auto on loss or on win this will make you suffer more of the loss
