In February 2012, I released Tetrizm, a Tetris game for the Casio Prizm. It offered five exciting Tetris modes, Marathon, High Speed, Touchdown, Sadistic, and Cascade. It ended up being a fairly popular Casio Prizm game, so when the TI-84 Plus C Silver Edition arrived in 2013, I quickly ported it to the new calculator. Tetric A brought Tetrizm's gameplay almost precisely intact to the TI-84 Plus C Silver Edition, and now, I'm happy to announce that I've ported Tetric A to the TI-84 Plus CE. Tetric A for the TI-84 Plus CE offers everything you'd expect from Tetric A/Tetrizm, including five fast-paced Tetris modes and high scores for each mode. Because there's no Doors CSE for the TI-84 Plus CE yet, you'll have to run prgmTETRIS with the Asm() token, but to make that easier, it includes a TI-BASIC prgmATETRIS that does that for people.
I hope you'll give Tetric A a try on your calculator, and I'd love to hear any thoughts, feedback, and if you find any, bug reports.
