Geez... naturally, you guys got all the great ones. The best ideas I've seen so far (for me) are 10K Pyramid, Second Chance, Big Showdown, Woolery Wheel, High Rollers and Gambit. But they're all great.
For what's been voted already, I would second Second Chance, just because. But as for new stuff, I haven't seen anyone vote for Cullen's $25,000 Pyramid yet. So how 'bout it?
