See it on iPhone Duo.
One finger
Drag left or right. Dodge the red.
The tunnel turns under your finger and the ball rolls on. Red blocks come at you faster and faster. There is always a way through: the tunnel never builds a wall you cannot reach in time.

Friends & records
Beat your friends.
Sign in to Game Center and every run goes to the Twist Tunnel leaderboard. See how far your friends got, beat their best, then wait for them to take it back. Open Records and tap Game Center leaderboard to see who leads.
Your own top ten stays on your iPhone, even offline.

Boosts
Shield. Slow time. Clear.
Roll over a boost and it works at once. No buttons to press.
- Shield The ball turns gold and takes one hit for you.
- Slow time Three seconds at half speed. The ball turns cyan.
- Clear A flash wipes the blocks ahead. Rare, and worth it.


Every 1000 m
A red banner. New colours.
There are no levels, only metres. Every thousand of them a big red neon banner flashes, the phone gives a tap, and the tunnel changes its colours.


After 2000 m
The blocks start to move.
Spinning bars and swinging blocks join in. They lock in place just before they reach you, so you can read them and pick your gap.

iPhone Duo
Fold it, bend it, open it.



Fold or open the phone mid-run and the tunnel follows in the new size. Stop half way and the run pauses until you tap. It plays just as well on any other iPhone.
