This past week on Buzzr we moved from bonus round #1 (Pick a number) to bonus round #2 (Pick 3 and win or risk-a-fur).
Though it wasn't a smooth transition since they skipped two episodes - the last show with Endgame #1 (Harvey/Lorraine/Debbie) and the debut of Endgame #2 (Tricia/Barry/Rose).
Based on the 25 episodes with bonus #1 aired on Buzzr, they had 8 wins, with 3 won consecutively and 3 won on the first try.
Looking at the 19 episodes Buzzr skipped with Endgame #1 (the first 18 shows of the series and the aforementioned last use), the car was won a total of 14 times in 44 episodes (on shows 1, 4, 8, 15-16, 23, 27-28, 33, 37-39, 42, and 44), a bit under 33%.
My gut says that win rate is what prompted the change in play.
I don't disagree, but my own gut says the fact $1,000 cash was the consolation prize for not finding the CAR screen was a contributing factor.
