This is the home page for Batrachians, a fly-eating frog video game. It is a clone of the 1982 Frog Bog video game for the Intellivision, from Mattel.

Batrachians 0.1.7 is out (2019-11-11). This version links with version 0.1.7 of the flatzebra library.

Requirements (on a GNU/Linux system): SDL, SDL_image, SDL_mixer. The sources might compile on other Unix-like systems.


You need to get batrachians and flatzebra. Your system is assumed to already have the required SDL libraries.

Game Play

The command batrachians runs the game. If you use GNOME, you should see an entry for Batrachians in the Games menu.

You control the red frog, and your goal is to eat more flies and score more points than the computer's frog, which is gray. A game lasts three minutes, during which day becomes night.

Above your frog, you will see crosshairs of the same color. You can move it with the four arrow keys. The crosshairs designate the highest point of the jump you want your frog to make. Typically, you should put the crosshairs near the fly you want to catch, and then hit the left Ctrl key to jump.

While in the air, you must press the left Shift key to make your frog stick out its tongue. Your frog will eat any fly that its tongue touches. Avoid falling in the water, as your frog will waste time while it swims back to a lily pad.

These controls may be difficult to master at first. You may want to always press left Ctrl and left Shift together to simplify things.

The Escape key quits the game.
