Your Number's Up is a fast-paced game for 2 to 6 players. The object of the game is to score as many points as possible, by completing simple sums. The first player lays a number card down and subsequent players have to complete the sum. The player completing the sum takes the three cards as their trick and starts the next round. Sounds easy? Well maybe! What happens if you cannot complete the sum? You have to pick up a spare card and wait for your next turn. This game can be played by people with all levels of ability and in our testing, we found some people with devious minds who tried to stop others winning tricks. I'm sure you wouldn't do this! It's fun, but make sure number isn't up by having a handful of cards at the end.
