Excellent idea, but the boosters/prizes were sometimes the same, eg 2 people suggesting unlimited lives for 30 minutes. I'd rather get a variety. Sometimes the rewards were not worth the effort it took to get past the levels.
I never get the striped brush or party booster, they just never come up as something you can win. I miss being able to collect the candies with the letter 'C' on them, & having them accumulate into extra boosters.
