Clumps
Clumps is a simple and surprisingly addictive game. You must clear the board of items but can only remove items in a 'clump' of at least 2 items. Larger clumps earn higher scores. Easy.
I originally encountered this years ago on RISCOS in a game of the same name. For second year compsci we had an assignment in which we had to submit a game written in C++/Qt and this was my entry. Since then it has been ported to Waba, back to C for PalmOS and then back to Java for MIDP.
The MIDP version is the most featured but doesn't quite look the best. It's using graphics primitives for the pieces so as to be scalable across many devices. But there is some animation there, keypad support and it's the only version I'm likely to update (more likely now I've finally got MIDP running under OSX, lazy bloody Sun...).
