There's this nice little game which seems to be the latest mania in every device, and still there's no VIC version . It was created by an Italian teenager, so I'd be particularly proud of playing it on my old breadboard.
A Commodore 16/Plus4 version can be found here, and there's also downloadable source code. If it was in BASIC, I would have tried the conversion myself, but it's not, so I'm asking if anyone's willing to do it .
If anyone is going to make one, please make it as a version of Threes instead. It's the original (1024 and 2048 are clones of it), and a much better, harder to beat game for starters. You can get some pretty high scores in 2048 without even thinking.
