A=B
Solve string puzzles with one rule: replace A with B
A=B is a puzzle game built on one rule. Each line of your program says: replace the text A with the text B. The game applies your rules to an input string until no rule matches any more. With only that, you solve tasks such as turning every letter into uppercase or multiplying two binary numbers.

About A=B
The puzzles make you think about algorithms in a new way, with string rewriting instead of variables and loops. You can also try to solve each level with as few lines as possible. Many levels are hard, so it suits patient players who like logic.
It is a paid game from Artless Games on Steam for Windows and macOS. It includes a level editor and Steam Workshop support.
