Gameboy Tetris wasn't the first Tetris I played (that was Mirrorsoft Tetris on the ZX Spectrum, with its spooky AY theme music), but it is the Tetris I always go back to.
For such an early GB game, it feels almost perfect. A compelling combination of apparent simplicity and hidden depth, it was (and still is) ideal to pick up and play for five minutes at a time. I think it is fair to say that the GB wouldn't have done half as well without Tetris.
Sure, it lacks features that modern Tetris implementations have - like hold, or being able to rotate infinitely in place, or fancy flashing backdrops - but it seems somehow better for that. Tetris in its purest form, just one more go, for ever and ever.
What are your memories of GB Tetris? Do you still play it? Do you think it holds up? What is your go-to Tetris?
At least in the case of the Tetris GB, there was no battery save in that cartridge. It really was a case of losing your score after every power off.
