The games only pay $0.01 per game completed, the "points" referred to at the end of some games are not at all related to the points which can be earned on our site to purchase items from the prize shop (http://www.cashcrate.com/prizeShop).
The points unfortunately are displayed on the game provider's end and it's something we've been thinking about asking them to remove. On the starting games page, we do say:
The new games pay cash! Play until you receive your high score and see the "play again" button to receive credit. Please allow up to 24 hours for crediting. There is no limit to the number of times you can play or the cash you can earn, so play away!
