Rainbow Walker is an action game designed by Steve Coleman for Atari 8-bit computers and published by Synapse Software in 1983.

[2] The player hops along a rainbow, changing monochromatic squares to color, while avoiding dangerous creatures and gaps in the surface.

The Double Play re-release of Rainbow Walker includes the game Countdown by Ken Rose.

[1] The player controls a small creature named Cedrick who hops on a flat rainbow curving into the screen, giving a pseudo 3D quality to the game.

One offensive opportunity is that if Cedrick steps on a fragile square, then it stops creatures moving for a few seconds during which time they can be stomped on and eliminated.

"[1] In 2014, Retro Gamer included Rainbow Walker on a list of the top ten Atari 8-bit family games.
