How to Play Mathness: Rules, Scoring & Strategy

Mathness is a fast, competitive number puzzle: you get one target number and five starting numbers, and you combine them with the four basic operators to land as close to the target as you can. A round takes about a minute. This guide covers the rules, exactly how scoring works, and a handful of strategies that move you up the board.

The rules in 30 seconds

  • You're shown a target number (say, 63) and five numbers (say, 7, 8, 3, 9, 12).
  • Combine them with +, −, × and ÷ to build an expression.
  • Each of the five numbers can be used at most once — you don't have to use all of them.
  • Standard order of operations applies (× and ÷ before + and −).
  • Get as close to the target as possible. An exact hit earns a big bonus, but a near miss still scores.

For example, with a target of 63 you could play 7 × 9 = 63 for an exact match using just two numbers — efficient and accurate. Want to try one right now? Play a free round and come back.

How scoring works

Mathness doesn't just reward the right answer — it rewards how you got there. Your score is the sum of several fronts, up to a maximum of 1,350 points per round:

  • Accuracy — how close your result is to the target. An exact match unlocks the largest single bonus.
  • Speed — faster submissions score more, on a 60-second curve. Hesitation costs points.
  • Numbers used — using more of the five available numbers is worth more than a bare two-number solution.
  • Step efficiency — fewer operators for the same result scores higher. Elegance pays.
  • Variety — mixing different operator types (not just repeated addition) earns a bonus.
The big lever is accuracy. A lightning-fast answer that's far from the target will lose to a slightly slower exact match almost every time. Lock onto the target first; optimize speed and elegance second.

Five strategies to score higher

  1. Hunt for the exact match first. Scan for two or three numbers that multiply or add straight to the target before settling for "close enough."
  2. Work backward from the target. Ask "what times what is near 63?" (7 × 9) instead of randomly combining tiles forward.
  3. Use division to bridge gaps. When you're a little over, dividing by one of the remaining numbers can snap you onto the target.
  4. Don't over-spend numbers. If two numbers nail it exactly, extra steps only add risk and time. But if you're short of exact, spending more numbers can earn the "numbers used" bonus.
  5. Practice mental math. Speed comes from arithmetic you don't have to think about — see our 7 mental math tricks for drills that translate directly into faster rounds.

Three ways to play

Once you've got the basics, there are three modes:

  • Solo — unlimited fresh puzzles. Every submission feeds the global leaderboard.
  • Daily — one shared puzzle for everyone, one attempt. Great for building a streak. Try today's puzzle.
  • Challenge — duel a friend on the same puzzles and see whose math is sharper.

That's everything you need. The fastest way to actually get the scoring is to play a few rounds and watch the breakdown after each one.
