Tetris, properly done: falling pieces, full-color board, and that one long bar that never shows up when you need it.
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.
Pick your mode
- Marathon: survive as long as you can and rack up points.
- 40 lines: clear 40 lines as fast as possible. A race, not a survival run.
- Time trial: score everything you can before 100 counts run out.
Controls
- Arrow keys (or 4, 8, 6, and 2) move and rotate the falling piece.
- tab stashes a piece in hold, or swaps it back out.
- enter drops the piece instantly.
- p pauses, r restarts.
- g toggles the ghost outline that shows where your piece will land.
Clearing several lines with one piece pays a lot more than clearing them one at a time, so building toward multi-line clears is where the big scores live. Each mode keeps its own top three scores with your name on them.
