Robot Unlock

Robot Unlock is a puzzle game in which you help a dweller from other-space solve challenging questions about computability. After years of trying, you finally manage to dial into other-space.

Solve the puzzles

Work through more than 75 levels, solving puzzles in constrained spaces with a handful of instructions. The game also presents open-ended problems, where you can design your own solutions. You can optimize those solutions for speed, number of instructions or space.

Tools and community levels

You can use multithreading, timing and synchronizing execution threads to halve the execution time. Breakpoints let you step backward or forward through your solutions. You can compare your results with other players using histograms, and create and share levels for others to solve, including community-made levels.
