SNATCH is the word game, pure and simple. It takes 30 seconds to learn and you'll play it for the rest of your life.
The idea behind the game - to make words and to poach words by adding to them - has been around since Victorian times.
SNATCH is addictive, loud and generally good fun. It does test your brain a bit but the most unlikely people are very very good at it. Plus, it looks nice.
