Games by 9io.
Two of our own games, designed for iPhone Duo and heading to the App Store. The same team that builds products for our clients designed, built and shipped them.

Bitfold
Bitfold turns your iPhone into a pocket game console: a glossy shell, a clicky D-pad, A and B, Start and Select. Closed, iPhone Duo is a pocket console; open, it's a clamshell with the hinge on the real fold.
- Ten original games we wrote for it, from a platformer to pinball
- Twelve colour editions, each with a matching Home Screen icon
- No ads, no accounts, no tracking
- Three of the games play free in your browser

Football Kick
Flick it. Bend it. Bury it. A one-finger football game for iPhone and iPad: fold iPhone Duo like a laptop and the pitch lies flat on the table while the goal stands up behind the fold.
- A World Tour of 30 levels across six grounds, with six keepers
- Swipe speed is power, a longer swipe lifts it, a curve bends it
- Play the real game engine free in your browser

A game has to feel right in the first second.
Touch latency, haptics, layouts that change when a phone folds, and no crashes when it does. Games test all of it at once, and we bring the same care to the apps we build for clients. See product engineering →
