In How Many Stars, players are 'Bidding' to get as close as possible to the answer to a question, such as "How many stars are in the Milky Way" or "What % of Brits like Simon Cowell", without going over.
Bid or Pass?
Players take it in turns to ‘bid’ on the answer, where the next bid must be a higher answer than the previous. If a player thinks that the answer has got too high, they can pass.
Reveal!
Once all players have passed except one, the answer is revealed. If the final player's answer is at, or below, the correct answer, they score points. If the answer is even just a fraction above, all the other players score points.
Confident?
Think you know the exact answer? Then slap your hand on the Star Card while shouting out the answer. If you're exactly correct, you score lots of points! If you're wrong, however, all the other players score lots of points! Risky.
