My kids like 'Abduction: World Attack' (or as they call it 'bouncy cow') I play FloodFill, Labyrinth Lite, TiltMazes, Orbs Knockoff Lite, TopSETGame, Zilch Free.

I used to play Word Wrench a lot and it was a big competition between my wife and I for high scores. Then one evening, I sat for an hour with a python script cheating the high score up to about 10 times our previous best. Got tired of it soon after.

EDIT. I told her right away. I just wanted to see the look on her face when she saw the new high score.
