Fish Buffet - How does the reward system work on the regular Fish Buffet?

Once you have collected enough points in the allotted time period to spin the Fish Buffet wheel, you will be allocated the reward shown at the end of the wheel spin, the percentage shown in the Fish Buffet tables denotes the average amount of rewards you can expect to receive eg 30% will mean 30% of your Fish Points (Fish Points have a nominal value of $0.01 each) will be converted to cash at that level, based on an average of 1 million wheel spins
