If we are talking the basic $25,000 pyramid format (IE no $100K tournament) Just play 4 rounds. 1 time is 10K, twice is 20K,3 30K, 4 40k. Or you can go to a "Scrabble-Like" format where the Champion Plays 1 semi final against 1 challenger and 2 new players play game 2. each playing the 1st game for $10,000.
For press your luck I'd up the rounds to 3 or 4 and up the whammies accordingly(either the max of 6 or 8). As far as top amounts I don't know

Only Connect could work as a show if they dumb it down a bit.
Divided looks like it has FOX written all over it.
the chaser seems like a good show maybe have more then one and do a team vs team format or maybe have a face the ace style 1 on one competition.

The shows themselves were pretty good. The Cheesy Jokes that "Mr. Q" quipped only are passible because 90% of the audience knows its Hal Sparks voicing it. The format is good. Cat did a marvelous job as hostess.
Is it just me or did anyone watch "The Money List" wondering how Fox messed this up? Its an amazing show. Has a play along factor probably not seen since "Duel". You know the kind that was what interactive TV was Before the internet.
