ORIGIN: US Tomy Pocket Game

VARIANTS: Tomy Pocketful

GAMEPLAY: Puzzle game. The channels up either side move backwards or forwards one row (for three possible positions in total) using the levers on the side of the case, and the object is to move the counters around until you've made four rows of identically-coloured counters. Very tricky, but doubtless easy once you've worked out a few sequences of moves.

VARIANT: Rack 'Em Up

ORIGIN: Tomy Pocketful

DIFFERENCES: Background colour only (black instead of brown). As with the Pocket Game version the name is printed in big letters at both ends of the case, but it's printed in gold/silver and so doesn't show up well in scans.
