I honestly don’t understand this terms for the use of faucet. You should just use play money if you don’t want to use the faucet to earn real money instead of using faucet with real money rewards if the goal is just to test the game.
I’m not familiar with your VIP rewards feature but if the rewards keep increasing on the faucet every time the players wager grow then it means that faucet is design to reward users achievements and not for testing purposes. CMIIW.
