They can be as simple as touching one icon on the screen to collect bonus credits. Pick-a-prize bonuses, or just pick’em bonuses, have been a staple of video slots since the late 1990s. Introduced on the game Vegas Hits, U-Spin puts a bonus wheel atop the machine, but also puts a video representation on the screen. One more twist on the bonus wheel has been Bally’s U-Spin technology. The most lucrative bonuses will occur the least often. Not all bonuses occur equally as often in Bally’s Michael Jackson: King of Pop, WMS’ Journey to Oz or any other game that uses a wheel spin to initiate free spin or pick’em bonuses. The same kind of weighting applies to bonus wheels that initiate other bonus events in addition to awarding credits. And since the weighting of numbers means frequent 60- and 50-credit wins, players aren’t discouraged by the bottom 20-credit wins coming up too often. With an average win less than half the 213 you’d get if all numbers occurred equally as often, game designers can have the bonus events occur more often.
The set is weighted so that 60- and 50-credit wins are the most frequent.The bottom prize of 20 credits still comes up once per 10 spins.The top prize of 1,000 credits now occurs only once per 50 spins.With that number set, we can tell the following things:
