I quite like Qwirkle, although that could be because I pwned the one time I've played it so far, think I got into the 130's by the end, a constant stream of qwirkles racks up the points nicely
Another similar one that I've played way more is Iota, way more portable but same basic idea with the extra element of a number. So there are 4 colours, 4 shapes and numbers 1-4, so any two cards next to each other, like qwirkle, determine the rules but there's an extra aspect. As they're cards that are ~1"x1" the box is tiny, not much bigger than a couple of qwirkle tiles
