Frogs and Flies (on the Atari 2600 and Commodore 64), and Frog Bog (Intellivision) consist of two frogs competing to zap the highest number of flies before time runs out. The play area includes two lily-pads with one frog on each. The grey frog is controlled by player one, and the red frog is controlled by player two, or by the game.
There are two difficulty modes, the first of which locks the frogs' flight path and landing point. The player simply decides when to leap, and when to zap a fly with the fire button. The tongue takes a moment to fully extend; timing the jump and tongue are the basis of the game
In the second difficulty mode, the frogs are not locked on to a single flight path. They are free to roam around the lily-pads, which affect the trajectory of the jump. In this mode, a frog can accidentally jump into the water, where the player will lose valuable time swimming back to the pad.
Each fly is worth two points, and the highest score wins when the timer runs out. Note that there is no onscreen timer, rather, the day progresses as the sky darkens to night. At the end of the game, a firefly brings out "The End" to the middle of the screen, and a "cricket chirp" sound is played until the game is reset.
