March, 2001 (updated April, 2001): Instaprizes have changed recently. In general, the prizes offered are not as lucrative as they used to be. However, some games are offering you the opportunity to win an instaprize more frequently.
Here's a table comparing the old instaprize system to the current (March, 2001) instaprize system:
| Table 1: How Instaprizes have changed | |||
|---|---|---|---|
| Old Instaprizes | New Instaprizes | ||
| Percentage of the time the instaprize is prizebucks: | 80% | 74% | |
| Percentage of the time the instaprize is one or more game credits: | 20% | 26% | |
| Average instaprize prizebucks value: | 24.3 | 13.9 | |
| Average instaprize game credit value: | 2.75 | 1.6 | |
| Links to sample rotations: | Old Rotation | New Rotation | |
Also, I have not recently seen any more than 2 game credits offered as a single instaprize (used to be 10), and the maximum prizebucks offered now seems to be only 30 (used to be 100)
