Perfection and Superfection were games made by Lakeside in the '70s
Perfection was a game where you put the shaped game pieces into their matching slots on the game board before a one minute timer expires and the board ejects everything. If you can complete it, you can stop the timer. If you couldn't, you were left picking up game pieces everywhere for 10 minutes.
Superfection had a two minute timer and puzzle piece blocks..
Somehow, I could never complete either of them before timer blew everything up.
