Trap the ball within a small enough space. This game was created entirely in TI-BASIC.

Instructions: use the cursor keys to move the cursor, 2nd to switch the cursor direction, and alpha to fill space on the opposite side of the cursor. If you attempt to split the ball, or run out of time, the game is over. Fill at least 90% of the play field to win.

The game is available for the French TI-83 Premium CE, as well as the American TI-84 Plus CE (and their Python edition counterparts). The game will also run on an American TI-84 Plus C Silver Edition, but I wouldn't recommend it as the calculator is not fast enough for a smooth experience.

I know it's not much, but I hope you enjoy the game regardless.

I absolutely love games like this! I used to play one on this batman toy computer thing that I had when I was a kid~ I'll definitely be downloading this and checking it out!

This game kind of reminds me of color switch, and those YouTube shorts where it’s like rainbow balls bouncing around that get bigger and they need to escape or something like that. Seems like a really fun game though, I’m gonna download it when I get home.

I have been made aware of an issue affecting the routines determining where you're able to start filling and am now working on a fix. Please hang tight.

UPDATE: The code has been cleaned up, the bugs have been fixed and I've added new features. I'm unsure if I'm able to update my download page, though.

Great work on this! I've approved the next version. An optional next step would be to optimize your program to save time and space. I've linked you a guide for doing this- in only a few minutes, I saved around 50 bytes (and I imagine that with that guide, you'll be able to do the same). I didn't even have to touch the lowercase letters (which are twice as many bytes as uppercase letters).

Thanks for approving the update! As for the optimisation, admittedly it's been a while since I've touched TI-BASIC. And indeed, this game was a prototype I had made a while back. I'll have a look at the article!

I played it last night and I think it's pretty fun! Like phoenix said, it could definitely use some optimization, but it sounds like you're gonna take a look~

Whoops. Looks like I screwed up, there was a bug where the game would be unplayable if you didn't set up variables X and Y, which I used erroneous commands to do. It should be fixed now!

Thanks for all the support you've given me for QIXBALL. It was really meant to be more of an introductory project, but I'm still more than happy to accept tips on how it could be improved!
