I like Back to '72 a lot. Great job on the retro look. They could have made the TV look a little better. And the TNPIR logo at the bottom looked a little off to me. This is basically Cliff Hangers with 50 steps instead of 25 which is fine. (I don't think the scale is necessary and only reminds people of Cliff and Range Game.) They could just use 3 prizes all each under $50 without providing a range and people will get the hang of it. Too bad they didn't use the 1972 SP cues. That definitely would add the the retro feel they are going for. Nevertheless, good to see a new game, and as I have said previously, after this season is over, they can just call it Back to the '70s and show the year each of the 3 prizes appeared (e.g. first one from 72, then 73, then 74, etc.). I would love to see this game played almost weekly this season for regular prizes, trips and even a retro car reproduction to keep w/ the theme!
And yes, this was intended to be Monday's show by the references made and it still should have been. They could have opened the show with the debut of this brand new game that celebrates this historic milestone since the $50K win was very likely, and bury $1Million Plinko as game 6.
