Lab Mice is a single player logic game played on sturdy, 6-inch square, dry erase puzzle boards. Each board has a grid printed with colored mice and cheese. The object of the game is to draw lines (with the sponge-topped dry erase pens) connecting each mouse to its corresponding color cheese without crossing any other connecting line. Lines must be drawn either horizontally or vertically using 90 degree turns; no diagonal connections are allowed. The game includes 50, 2-sided cards with three levels of play differentiated by the number of mice/cheese combinations that must be made on each card.

A 26-page booklet provides game directions, solving tips, and diagrams of completed puzzles. Lab Mice is an attractive game that is fun to pick up when you have a quick minute and want a challenge, and it can be used to test yourself again and again. Once, we actually played 25 games in a row. It is also a convenient car game. The dry erase feature makes it easy to erase if you change your mind or make a mistake - which, on difficult challenges like these, is a lifesaver.
