Schuco- 5 + 1 Multi Game (19??, LCD, Watch Batteries, Model# 7857)
Licensed from Epoch (Epoch's Game Box Penta), this is a 5 + 1 games-in-1 unit. The five built-in games are: Gold Rush, Downfall, Eggs-Plosion, Mystery Maze and Flip-Flop. Then there is the '+1' game which appears to be a combined version of all 5 games (maybe you solve one level from a game and then it automatically goes to the next game....). I guess I should play it a little and find out what it does. :) (German release)
Do I have this? Yes, boxed.
