One rule: stay in the white part of the tunnel. The tunnel disagrees with your plan, gets faster, and squeezes thinner the longer you survive.
How to install it
- Download the game with the button above. You'll get a .tns file, the file type TI-Nspire calculators use.
- Open nspireconnect.ti.com in Chrome on a computer or Chromebook, and plug your calculator in with its charging cable.
- Choose File Transfer, then To Calculator, then From Computer, and pick the .tns file you just downloaded.
- When it lands, the calculator shows a prompt. Choose Open and you're playing.
TI's web app only supports the CX II and CX II CAS. If you have an original CX, or you already use the TI-Nspire Student Software, sending the file through that works the same. The game lives in My Documents afterwards, so you can reopen it any time.
How it works
Your ship flies forward on its own. You steer sideways with the left and right arrows, or 4 and 6 if you'd rather keep your fingers on the number pad.
That's the entire control scheme. The difficulty comes from the tunnel itself: the walls drift, the safe lane narrows, and the speed keeps creeping up until your reflexes lose.
It's the kind of game where run one lasts eight seconds, and twenty minutes later you're still trying to beat run nine.
