About Gravirinth

According to legend, a forgotten civilization once mastered the power of gravity, which they used to travel across the Milky Way, in search for alien life. Eager at first to share their wisdom, soon they became aware that most alien life forms were not ready to receive this great power...

So an enigma was devised to test the intelligence of alien societies, a puzzle marvelous yet so obscure that finding it would be a challenge in the first place. Thus the Gravirinth were born, each hidden into the most promising solar systems.

In the next millenia, few Gravirinth were ever found, and even fewer yielded their secrets, a rare moment of great joy where two civilisations found they were not alone in the vast cosmos. In the Solar System too had once a Gravirinth been found, but its location was lost to mankind...

...until Xeno, the Exoarcheologist, arrived. Will the Gravirinth reveal its mysteries?

How to play

Experience the instruction set below in Gravirinth's interactive tutorial!

Gravirinth tutorial 1:move and switch gravity

Navigate the Gravirinth with the arrow keys. Step on gravity beacons to change your specific gravity! The controls change accordingly.

Pick any number of blocks with the downward arrow key. Place them strategically with the upward arrow key to overcome obstacles!

Gravirinth tutorial 2:pick and carry blocks
Gravirinth tutorial 3:throw a block

Blocks also have their own specific gravity! Push blocks in your way or throw them horizontally to a higher platform!

What if two specific gravities collide? An unstable gravity field materialises, keeping everything in place. Untangle the collision, and it eventually vanishes!
