Most players finish in about two minutes. It's ten rounds, one word each, with the letter sequences growing from two letters up to five.

Your time is tracked so you can chase a personal best and challenge friends, but nothing runs out. You can take as long as you like and guess as often as you like.

Your streak is the number of consecutive days you've completed the Sprint. Sign in with a free account to keep your streak safe across devices.

When you finish, share your result and Wordspine creates a link that remembers your time. Whoever opens it plays the same day's puzzle and sees a head-to-head comparison at the end.

Each day's Sprint is a one-off run, and a new puzzle arrives the next day. Signed-in players can review their past results and times in Stats.
