SOLO CHESS by Jim and Charlie Gerrie.

"Solo Chess" gives you 40 different chess puzzles. Playing in a 4x4 board, you have to capture a piece with each move. Quite fun and challenging, regardless of your skill - or lack of such - at playing chess.

SHOPLIFTING BOY by Jim and Charlie Gerrie.

In this game, you have to steal the "$" without being seen by the shopkeeper. You can hide behind the shelves in the center aisle, but be careful, as soon as the keeper sees your head, you are going to jail, even if you have not picked up anything yet.
I struggled a bit with the control's response, but not enought to ruin the fun.
