Frogger was released on June 5, 1981 by Sega. The game was developed by Konami. Frogger is a puzzle and strategy game.

The game starts with three, five, or seven frogs (lives), depending on the settings used by the operator. No game in North America ever was set above 3.

The player guides a frog which starts at the bottom of the screen, to his home in one of 5 slots at the top of the screen.

The screen was divided into 2 sections with hazards. The lower half of the screen contains a road with motor vehicles, which in various versions include cars, trucks, buses, dune buggies, bulldozers, vans, taxis, bicyclists, and/or motorcycles, speeding along it horizontally.  The upper half was a river with logs, gators and turtles.

The middle part of the screen is a rest area that a player can use to await a way across the water. The player can also use a log to move down the river but he will die if the log reaches the edge.

Frogger has more ways to die than any other game released up to 1981.

The game starts easy and rises in difficulty as levels go up. The levels cycle every 5 and reset.

Game supports 2 players taking turns.

The game uses the Z80 CPU with 244×256 RGB color graphics.
