You are an insomniac in desperate need of sleep. The only solution: try to count sheep. Unfortunately, you're also a perfectionist and the rules of what kind of sheep can be counted keep changing!

• DRAG SHEEP TO THE LEFT TO RETURN THEM TO GRAZE. 
• DRAG SHEEP TO THE RIGHT TO COUNT THEM. 
• THE SHEEP MUST MATCH ALL THE ATTRIBUTE REQUIREMENTS
• IF THERE ARE CONTRADICTING ATTRIBUTE REQUIREMENTS, BOTH ARE ALLOWED
