Pff, there are so many. The newest one is from 1995/6(!) Pocket Repeat model 60-2152 = Tiger Ditto Pocket Repeat model 60-2468A = ? Pocket Repeat model 60-2482 = Tiger Copycat Jr?
BTW I wonder what MCU is in Tiger Lights Out. The 1st version is from 1995, it takes 4.5V batteries. https://en.wikipedia.org/wiki/Lights_Out_(game) http://www.jaapsch.net/puzzles/lights.htm
