After some thought I've tweaked the pricing game idea I called Time Travel some, so here I go.
This version is more akin to To The Penny. Four or five grocery items or small prizes are placed on a table, with a price below them. The price displayed is the item's ARP adjusted back to a certain year. Below the first item is a choice of two possible years the item traveled back in time to. Below the second, three choices and so on.
The contestant must guess which year the item traveled back in time to, picking from the possible choices below the item. If s/he gets the first one right, they win $2,000. The contestant can decide whether to stop there or keep going. The process repeats. If the contestant guesses wrong on one item, s/he loses all the money they've won and the game ends in a loss. However, if they get all of them right, they win $16,000 and/or a bigger prize revealed at the beginning of the game.
There would be a way to eliminate wrong answers a la WWTBAM but I have no idea what that would be at this time.
Thoughts?
