Stone Sling

In the game, two players face off with catapults and attempt to knock each other's tower down. In North America, the game featured compatibility with "The Voice of Odyssey²" expansion module. It was also later released for the Philips Videopac+ G7400. It is heavily criticized for its simple and solely timing based gameplay. Some consider it a decent game for young kids. The game's realistic sound effects with the addition of the Voice module are often complimented.

Two players take control of soldiers on either side of the screen, each with a catapult and a tower. Each player at any point can fire their catapult at the opposing tower in an attempt to knock it down. Holding any direction on the joystick charges up a shot and releasing fires the catapult's projectile with increasing distance depending on how long the joystick was held. If a player hit's their opponents catapult, it gets destroyed briefly while the opposing player grabs another one. A player loses when their tower is completely destroyed after nine hits. There are three difficulty modes which control the level of tension in the catapults, meaning projectiles take less time to fly farther on later difficulties. Later versions for the Videopac+ include enhanced graphics and a colorful background. • Illustration — A projectile from the blue player about to directly hit the red player. The game's graphics are naturally off center. This game supports "The Voice" expansion module. With the module, there are explosion sound effects, and a voice which commentates the game, taunting or praising players depending on how well they aimed their boulder (using phrases like "Come on turkey, hit it!"). It also makes a gurgling noise if a stone lands in the water.

Stone Sling was first released in Europe by late 1981 along with other European along with other Videopac games Laser War and Catch The Ball / Noughts and Crosses. Also at the end of 1981, a new team of developers were hired at North American Philips Consumer Electronics in Knoxville, Tennessee. Among this new crew hired was Robert Cheezem, who was tasked with converting the game for the North American market. Cheezem hit a road block at one point caused by the game's code not finishing by the time the next frame was to be drawn.
