| ORIGIN: UK Pocketeer no. 31324 (1977) VARIANTS: Election, Popatron GAMEPLAY: Very basic against-the-clock ball-shooting game. You fire the balls into the nine slots in the atomic nucleus, but be sure to hit "Stop" to claim your score - if you leave it too late, the timer runs out and springs a trapdoor, causing all your scoring balls to fall through the floor and leave you with nothing.

| VARIANT: Election ORIGIN: US Tomy Pocket Game DIFFERENCES: Name only. Since the game bears no connection with any sort of electoral process, we can only assume it was supposed to be called the much more logical "Electron", but an unfortunate typesetting error went unnoticed until it was too late.
