This puzzle game will definitely put your IQ to the test. The cow needs to make it to the goal, but it can only travel straight in the direction it is facing. You have arrows that will change where the cow walks, but you only have a certain amount given to you. There is a password system, so you can stop playing and take a break from a puzzle that is making you pull your hair out. The game is in German, but it is pretty self explanatory once you get going. Viel Spass!
