About M-CODE

In 1977 NASA launched Voyager 1 on its never-ending journey.
But in 2067 Voyager 1 stopped responding, and NASA considered it lost.

Years later, NASA engineers found an unknown device, similar to Voyager 1's digital tape recorder. The device, built from Voyager 1 parts, was not made on Earth. It is a kind of puzzle, teleported to Earth by unknown extraterrestrials.

Now you have the chance to solve the puzzle — and to see what they want us to see.

HOW IT PLAYS
• The device's round screen shows a space image, scrambled by a hidden sequence of steps
• Guess, memorize and repeat the sequence — the controls surface from a pool of molten gold
• Three mistakes reset the attempt; accuracy and speed earn a perfect 1000
• Every perfect level reveals a piece of the big picture
• Reveal everything to decode the final transmission

FEATURES
• 60 levels across four control types: arrows, colors, letters and alien icons
• Completely free — no ads, no purchases
• A story with a real ending
• Rebuilt for modern Android
