It unlocks when you finish the Daily. RACE YOUR FRIENDS • See your Game Center friends' times on every puzzle you've both played: before you start, while you play and when you finish. • New games start on a puzzle a friend has solved, and the clock shows the next friend to beat. • Send a friend your time in a tap, see who's ahead this week, and keep a record against each friend. • Challenge friends on each Daily, and share any puzzle as a head-to-head race. • Each hint adds 30 seconds, so everyone gets a time.
