How to play

You get five starting numbers and one target. Your job is to combine numbers step by step until only the final target remains.

Example:

2 + 5 = 7
6 + 1 = 7
7 + 7 = 14

Tip: division must create a whole number. Use undo if you need to try a different route.

Scoring

Your score is based only on how long it takes you to solve the puzzle.

1,000 points minus 1 point for every elapsed second
  • The timer starts when today’s puzzle first loads and continues if you refresh or return later.
  • Retrying does not add a separate penalty, but the timer keeps running.
  • Using a nudge adds 90 seconds to your elapsed time.
  • The minimum score for a correct solution is 100 points.

Example: solving in 3 minutes earns 820 points.
