From VPG:
Ever wanted to make your friend bark like a dog three times, while rubbing their belly and slapping their knee? Then we have the perfect game for you!
Rules Lawyer, by designer Nathan Hansen, is a hilarious, fast-paced, family-fun card game for 3 or more players with ever-changing rules (“Laws”). Each player takes turns placing, altering and then obeying the current Laws of the game.
Your goal is to fulfill three Goal cards in your hand, therefore you must change the Laws (or hope someone else does) to your advantage. But beware, if you – or someone you spot – doesn’t perform all of the Laws correctly or in order, you may lose some of your Goal cards, or players could steal Goal cards from you!
