If I remember it correctly, I made around 15x buy feature but not even single buy gave me at least what I paid for the feature LOL.
It was the 6th bonus buy and it was probably my last attempt on that slot because I thought that I need to save up some balance to prepare for the 3rd week. Out of the previous 5 bonus buy, only one made profit and the 6th hit 3294x. IIRC, I probably made few bonus buy in this slot as well in the past but most of them ended up draining my balance instead of making profit for me lol
The volatility for this is slot is probably higher if not at the same level with Money Train 2
Arallmuus, nice wins, congrats mate! Keep that momentum going 
I wish I could lol but I know that I might lose alot after that crazy hit. Things are definitely not going to go well everytime for me
