This is a really interesting site. While it does look a lot like CSGODouble, it is not. You choose which team you think will win, and it shows who won the game each round, raising the suspense. I've never gambled before, and I still managed to blow all of my coins here. Really fun.
Step 2.) Click "Free Coins" and enter the code "PROMOCODE", you will be awarded with 100 free coins, which you can either bet or withdraw a skin with.
