Simplistic but priced appropriately. This is a collection of board puzzles where you are given chess knights that need to end up in specific spots. Similar to peg solitaire. Teaches graph theory.

This game is hard to put in a box. You will be asked to think outside the box. Very challenging puzzles posed in a philosophical manner. I would call it more of a journey than a game. Very rewarding.

A visual and comical approach to teaching low-level programming. You lay out coded instructions for an office peon to carry and modify the right data. Teaches many algorithms. Lots of challenges.

A very minimalist game, priced appropriately. A collection of peg solitaire puzzle variations where you hop different coloured pegs over one another. Simple, but challenging. Teaches graph theory.

A challenging game with minimal graphics. Your task is to program an old-school computer using a language similar to Assembly. A technical manual is your guide, and logic will be your sharpest tool.

An excellent game for learning low-level programming. The hardware design side of the game is limited, but the coding and logic is quite robust. Uniquely uses a technical manual (similar to TIS-100).
