Sig.Null

Sig.Null is a puzzle game set in a complex computer system with its own laws. You control mono-drones and use them to place tetra-blocks in their designated places. Your goal is to reach the System Core and discover how this techno world was born.

Discover the system

You uncover hidden rules of the game world as you progress. The levels are non-linear, so you can choose from a few levels to try at any time and return to one you cannot solve later. More than 100 levels introduce the rules step by step.

Mono-drones

There are up to 8 types of mono-drones, each with individual features such as exploding, swapping, infecting and controlling time.
