Vegas2web has the weekend promotion of 40% bonus with the lowest wagering requirement ever compared to other rival casinos which is 4.29X (deposit + bonus).
I made the minimum deposit of $25 and won it up to $125 playing cosmic episode 1 at 80 cents per spin, but I lost all back after I switched to play Ocean Treasure. Immediately, I made another $25 deposit and played Spartan Slot, I had it up to $90, then I increased my bet from 75 cents to $1.50 per spin, then you know what would happen, lol, I lost it all back again.
I think if you are patient and stay with small bet, you will be up with this bonus easily. I might try again next week because my gambling budget already reached the limit for this week, hehe.
