Donkey Kong II

Mario has captured Donkey Kong and put him in chains. Donkey Kong Junior must brave snapjaws, sparks and birds to get up to where papa is held prisoner to open each of four locks holding Donkey Kong.

Donkey Kong Jr. must throw the key at the bottom of the screen to the upper screen and then navigate to the top screen to unlock four chains while avoiding enemies the electrical sparks, Snapjaws and birds.

Score 1 point when Junior jumps over a spark or snapjaw. When each lock is opened between 5 and 15 points is awarded depending on how quickly Junior gets the key to the lock. A further 20 points is awarded when all 4 locks are opened and Donkey Kong is freed.

A miss is scored when Junior is bitten by a snapjaw, shocked by a spark, or pecked by a bird.

When the score reaches 300 points one life is added. If there are no misses the game goes into Chance Time where all points are doubled until a miss is scored.
