Reward Levels:
I am a big proponent of reward levels. Not all swipers are equal. Some swipe more than others and should be rewarded. Not punished as the existing rules are applied.
For example there should be more award levels for reaching certain plateaus.
300 gold :. 10% bonus on account
600 gold : 10% bonus on account. Plus half of all ads are 30 silver.
1000 gold :. 10% bonus on account. Plus all ads are 30 silver.
Rewards are needed to entice people to swipe more.
