Frogger

Frogger is an action arcade game with single-player and alternating two-player modes. The objective is to guide frogs safely from the bottom of the screen to the home slots at the top. Each attempt requires crossing a busy multi-lane road filled with cars, trucks, and other vehicles, then navigating a hazardous river filled with moving logs, turtles, alligators, and other obstacles. A successful run places a frog into one of the home slots, and once all five are occupied, the player advances to the next, more difficult level. The game has no conventional ending, instead continuing through increasingly difficult levels until the player runs out of lives.

Movement is tile-based, with each input moving the frog one space up, down, left, or right. This makes timing and positioning equally important, as the frog must avoid traffic, line up with moving platforms, and reach the home slots precisely. Vehicles move horizontally across the road at varying speeds, and contact with any of them costs the frog a life. After crossing the road, the frog reaches a median strip before entering the river section, where the water itself is deadly. To cross, the frog must ride on moving logs, turtles, and other floating objects. Some turtles periodically dive beneath the surface, forcing careful timing. Later levels introduce additional hazards such as snakes, otters, and alligators, whose open mouths are dangerous to touch.
