Pure Logic

Explore logic symbols. Discover the rules. Solve complex puzzles. Feel the power of your logical side!

Pure Logic is a puzzle game based on logic in its raw and pure form. Use your deductive reasoning skills to conquer more than 200 unique puzzles.

Each puzzle consists of an array of interconnected logic gate symbols. Some of the input/output signals are initially set, some are not. The challenge is to figure out and set the remaining signals so that all symbols are satisfied.

No prior knowledge of logic gates is required to start playing. The in-game training grounds let you explore the different symbols, and you'll quickly discover and learn the basic rules.

There are no time limits. You can enjoy solving all the puzzles at your own pace.

Pure Logic was initially released with a last-step-only undo mechanism. Due to popular demand "The Big Flexibility Update" was released in June 2023, adding support for unlimited undo. The update also added the possibility to change any set signal directly to the other colour/state, or reset it back to its original unset state. This opens up for a wide range of solving strategies.

The gameplay is based on real-world logic gate symbols and the Boolean functions they represent. Logic gates are the basic building blocks of digital electronics and computer hardware. Boolean functions play a crucial role in all levels of computer programming.
