ORIGIN: UK Pocketeer no. 31281 (1975)

VARIANTS: Time's Up, Dragon Trap. Time's Up is the US Tomy Pocket Game version, and is identical to the UK one except for the extra letter in the name.

GAMEPLAY: A simple maze game, where you have to get the ball from A to B before the time runs out. When the time does run out, the maze is raised against the surface of the play area, wedging the ball solidly in place to prevent sneaky cheating.

VARIANT: Dragon Trap

ORIGIN: MB Pocketfuls game

DIFFERENCES: Name, colour and graphics - the hazards of the dragon's dungeon actually partially obscure the maze walls, making the game slightly harder. Also, you actually have to travel the maze in the opposite direction compared to Time Up.
