We talked before on these intarwebs about an earlier pilot for Hollywood Teasers (which TVPMM has the music from) and I wondered how I would execute the show if each answer meant giving away a clue. I think the answer is rather simple. Play it like nighttime (or syndicated, if you prefer to say that) Squares. Play your first two games for X dollars/points, play remaining games for X-times-2 until time runs out, finish any puzzle in progress on the buzzers (a'la Classic Concentration when they ran short on time). I have a bonus round idea that builds off of that concept as well.
I always loved the Blitz word game, and I really hope they get a run at it on television.
