Bomb Jack[4] is a platform game published by Tehkan for arcades and later ported to home systems.

The game's antagonists are enemies such as birds and mummies which, once they drop in the bottom of the screen, can morph into enemies such as flying saucers and orbs that float around the screen, making Jack lose a life if he touches them.

[8] In Japan, Game Machine listed Bomb Jack on their May 15, 1984 issue as being the third most-successful table arcade unit of the month.

[11][12] Two years later, Bomb Jack returned to the top of the UK all-formats sales chart when it was re-released on the Encore budget label.

[16] Bomb Jack II is a licensed follow-up developed for 8-bit home computers by the British games publisher Elite Systems in 1986.
