Frogger

Each attempt requires crossing a busy multilane road filled with cars, trucks, and other vehicles, then navigating a hazardous river filled with floating obstacles.

A successful run places the frog into one of the home slots, and once all are occupied the player advances to the next, more difficult level.

The road portion is the first challenge.

Vehicles move at varying speeds, and contact with any of them instantly costs the frog a life.

Once across the pavement, the frog must contend with the river, where the water itself is deadly.

The frog rides on moving logs, turtles, and other floating objects to cross.

Some turtles periodically dive beneath the surface, forcing careful timing.

Alligators and snakes appear on higher levels, with their heads being dangerous to touch.

The home slots at the top of the river present their own challenges.

Only empty slots can be occupied, and some may be blocked by alligator heads.

Occasionally a lady frog appears on a floating object, and safely escorting her to a home awards bonus points.

Flies sometimes appear inside goal slots, also offering a scoring bonus when captured.

Each level is completed by filling every slot before the timer runs out.

Scoring is based on survival and efficiency.

Points are earned for every forward movement, successfully guiding a frog home, escorting the lady frog, eating flies, and surviving longer durations.

The game ends when the player runs out of lives.

The original arcade cabinet supported one or two players alternating turns, while early home ports to systems such as the Atari 2600, ColecoVision, and Intellivision recreated the core gameplay with graphical compromises.

Later console and computer versions sometimes altered level design, added new obstacles, or provi
