Users receive Free Spins for the mini-Wheel as a reward for leveling up.
The higher the level, the bigger the amount of Free Spins they receive.
Free Spins rewards are doubled during the week-ends, just as the regular free rewards. However, the maximum number of Free Spins you can have at any point is 20 and you need to claim any available Free Spins before claiming your regular free reward.
You can check your current level up progress on your Profile page or in the top right corner of the website.
Note: In order to claim Free Spins you need to have at least one previous deposit since you registered on CSGO500.
