Duometry vs Fold Fire

How well can you judge an angle? Duometry challenges you to match a target angle as closely as you can. Fold a compatible device or adjust the on-screen dial, lock in your guess, and discover how close you came. Play solo over 5 or 10 rounds and aim for your best score. Pass one device between 2–8 players for a friendly competition. Everyone’s guesses stay hidden until the shared reveal. Find out who came closest, compare scores, and keep playing. Explore angles at your own pace with the dial. On hinge devices, Free Measure lets you read the device’s fold angle directly. Come back for a daily challenge with three targets. Different daily modes put your angle intuition and visual memory to the test. Play offline, with no account required.

Got a few minutes to kill? Fold Fire is made for exactly that. Play on a flight, on a train, in a queue, or whenever you’re just waiting for something. Place your shot, fold the field and see where it lands. The rules are simple, but hitting the target exactly where you want takes a bit of practice. PLAY OFFLINE No internet needed. Just open the game and play wherever you are. QUICK ROUNDS One round only takes a few minutes. Play once or keep going and try to beat your best score. PLAY TOGETHER There’s also a local two-player mode. Share the same device and choose the number and size of targets and shots. INSPIRED BY A PAPER GAME Fold Fire is based on a paper game I loved as a child. I tried to keep that feeling through the design, animations and sounds. BEST ON iPHONE DUO The game was designed with iPhone Duo in mind. On Duo, opening and closing the phone becomes part of the game itself.
