The daily numbers game, scored against par
Six numbers, one target, one board a day. Reach it in as few steps as you can; every board has an exactly computed par. No ads, no account. A $4 pass adds the archive, practice boards and stats.
- Today's puzzle is always free, with 100 days already scheduled
- Archive of every past daily puzzle (it starts 16 Oct 2026 and grows by one board a day)
- 60 practice boards from par 2 to par 5
- Full stats: three-star finishes, finishes at par, streaks, average steps over par
- Three extra themes, including a mono theme with bigger numbers
Here is an example board in the Parsum style (it is not one of the game's boards). Your numbers are 100, 7, 6, 3, 2, 2 and the target is 381. Combine two numbers at a time (add, subtract, multiply or divide; subtraction stays above zero and division must be exact) and reach the target. The par is 4 steps: no route is shorter, and the solver found one. Here it is, so you can see what par means:
- 100 − 3 = 97
- 97 × 2 = 194
- 194 × 2 = 388
- 388 − 7 = 381
The share card after a par finish never shows a number from the route, only the target, par, your steps and the operations in order:

Made for
Who it's for
A score you can aim at
Stars come from steps against par, the exact fewest steps. There is no 'close enough': every board can be reached exactly, so the question is how cleanly.
Every board checked twice
Par and reachability are computed by an exhaustive search and confirmed by a second, independent program for all 160 boards.
Calm by design
No ads, no account, no timer pressure. Progress and streaks stay in your browser, and the new puzzle arrives at midnight on your clock.
A solver that shows the route
The free Parsum solver finds the shortest route for any six numbers and target, and says so when the target cannot be made.

Questions
Good to know
Is the daily puzzle really free?
Yes. Today's puzzle is free forever, with no ads and no account. The $4 Supporter Pass unlocks the archive, practice boards, stats and themes.
What is par?
Par is the smallest number of steps that reaches the target, found by an exhaustive search and confirmed by a second program. You cannot beat it, so finishing at par earns three stars.
What happens to my progress if I clear my browser data?
Streaks, results and your saved pass key live in your browser's local storage, so clearing site data erases them. Your pass key still works if you paste it again; keep the page you saw after paying.
Is this a copy of another game?
The format (reach a target by combining numbers) is an old one: the Countdown numbers round, NYT Digits and Make 24 all use it. Parsum's name, interface and par scoring are our own.
What if it doesn't work for me?
If it doesn't work as described or you can't access it, email us within 14 days and we'll fix it or refund you. See the refund policy for details.
