Can some old people here help me maybe? I’m looking for an educational game from the late 80s or early 90s, most likely written in GW-BASIC. It explained logical operations to kids.

The game showed several mechanical hands that you could retract or expand using levers. The goal was finding the right sequence to put a ball down without it damaging anything. At first the levers controlled the hands directly, later through various junctions (logical ops).

Does anyone know the game or a remake?


Found it, both the original (Russian game from 1989, runnable in an MSX emulator) and a Windows remake with worse (!) visuals. Screenshot shows the original.

@WPalant nice. Rocky's Boots was another logic-gate-related app; I played it on Apple II I believe.
