Split decision wasn't played here was it?
1981 definitely featured Take Two & Hi-Lo, didn't feature Plinko, Secret X or Punch a Bunch. Also had Trader Bob (can't remember what it was called though) as well as Give or Keep, Poker Game, Shell Game, and surprisingly enough It's Optional. I'd has-it-a-guess that what Fiona McDonald is referring to in that clip is the current rotation.
1989 had Credit Card & Clock Game, didn't have Bargain, Bonus, Bullseye, Bump, Hi-Lo, One Away, Penny Ante, Pick A Pair, Plinko, Punch a Bunch, Take 2, Ten Chances or 3 Strikes
When I was a small child, I had about 10 videotapes full of TNPiR, and I also taped every 89PIR. Being I was also a dull child, I decided taping over them would be a great idea... They were all on high rotation during weekends and school holidays
