Our Expert Score

89/100

Duometry takes a simple mathematical concept and turns it into an incredibly addictive, elegant casual game. Testing how accurately your eye can judge a 47-degree angle vs a 52-degree angle sounds straightforward, but it creates instant competitive tension.

The pass-and-play multiplayer mode is a standout feature for party settings. Keeping everyone's guesses hidden until the final reveal leads to great moments of playful rivalry. The UI is clean, modern, and completely distraction-free.

Whether you are playing the daily spatial memory challenge or passing the phone around among friends, Duometry is a clever, refreshing puzzle title.
