In 1977 NASA launched Voyager 2 — sixteen days before its faster twin — on the Grand Tour of the outer planets. It is still the only craft to have visited Uranus and Neptune, and Triton: an ice moon hiding a dark ocean under its crust.

Around 2030 its power faded and Voyager 2 fell silent, as foreseen. Decades later, a capsule of strange ice was found drifting near Earth. Its core was built from Voyager 2 parts — but it was not built on Earth. Inside lies a device: half machine, half a pool of liquid that trembles at the touch of a finger. A writing slate, made by something that lives in water.

Learn their flowing script, solve the puzzle — and 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 water glyphs

• Draw the glyphs on the liquid slate — discover, memorize and redraw the sequence

• A stroke the slate cannot read washes away for free; only a wrong glyph costs points

• 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 read the answer from the deep

FEATURES

• 60 levels across four glyph scripts: currents, tides, star paths and Golden Record engravings

• Glyphs that swim, fade and hide as the water deepens

• Completely free — no ads, no purchases

• A story with a real ending
