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.
- Tap two lit numbers.
- Choose +, −, ×, or ÷.
- The two numbers you used stay on screen but become dim.
- The result becomes a new lit number you can use next.
- Keep going until one active number remains: the target.
- When you hit the target, your score is saved automatically.
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.
