How to play

• Pick four words that have something in common, then press Submit.
• A group can be anything: places, people, phrases, wordplay. Look out for words that seem to fit more than one group.
• You start with 1000 points. Each wrong guess costs 100, but you can keep guessing as long as you like.
• The clock starts when you press Start. Finish in under 45 seconds for a time bonus of up to 300 points. It stays full for the first 15 seconds, then drops by 10 points every second.
