Elektronika IM-03: Tajny okeana

Elektronika IM-03: Tajny okeana (literally: Mysteries of the Ocean) is a Soviet clone of Nintendo's Game & Watch Wide Screen: Octopus.

The player needs to guide three explorers equipped with scuba gear pass a waiting octopus to get a hold of the sacks of gold hidden in a shipwreck. The player has to get as much gold as he can without getting touched by the giant squid. If the latter touches the character he's immediately captured by it. The game has two difficulty settings: Game A and B.

The handheld has a built in-clock and alarm.
