Free Math Games and Puzzles - No Download
Free math games and puzzles for anyone who likes thinking in numbers and logic instead of worksheets. Build an equation to hit a daily target, explore where number-shaped ideas can take you, and reason your way through rooms one rule at a time. These are short brain games you can finish in a few minutes or stretch into a streak, covering mental arithmetic, order of operations, lateral thinking, and deduction. The heart of it is the Number Lab: Four Nines as a daily habit, the 145-year-old Four Fours, and the 24 Game — each with an exact solver that shows every answer or proves a target impossible. Everything runs in your browser on phone, tablet, or desktop, with no download, no sign up, and no account.
Games in this collection
- Four Nines — The classic four nines puzzle as a daily game: combine four copies of today's digit — nines when you're lucky — with +, -, ×, and ÷ (order of operations counts) to hit the target.
- Infinite Levels — An exploration puzzle where every number-shaped idea is a place — select text to uncover hidden levels.
- WIN OR DIE — An endless two-door logic puzzle: read each room's rule, then pick the door that survives.
The Number Lab
Three takes on the same old idea — take a small handful of numbers and a few operators, and hit a target. The Number Lab is where all of it lives: a daily habit, a set of exact solvers that never bluff, and a page for every target from 1 to 100. Every solution is checked with exact fraction arithmetic, and where a number genuinely cannot be made, the page says so and can prove it.
Four Nines
The daily hands you four copies of the day's digit — nines when you're lucky — to combine with +, -, ×, ÷, and order of operations. The solver sticks to the four-9s canon: a worked answer for every target from 1 to 100.
- Four Nines daily — one new target a day, with a streak
- Four Nines solver — every target from 1 to 100, with four 9s
- Make 100 with four 9s — the famous 99 + 9 / 9
- Make 73 with four 9s — a genuinely awkward one
Four Fours
The 145-year-old original, in print since an 1881 puzzle column. Four 4s for every target from 1 to 100 — including the five that provably cannot be done.
- Four Fours — the 1881 original, with its history
- Four Fours solver — all 100 targets, the impossible five flagged
- Make 73 with four 4s — the most famous impossible one
- Make 64 with four 4s — a clean, satisfying build
The 24 Game
Any four digits from 1 to 9, and one target: 24. Type a hand — 3 3 8 8 and 1 3 4 6 are the famous fraction ones — and get every distinct way to reach it, or a proof there is none.
- Make 24 solver — any four digits, every solution or a proof of none

FAQ
Are these math games free, with no sign up?
Yes. Four Nines, Infinite Levels, and WIN OR DIE are all free to play, with no account, no payment, and no download. Open the page and start playing.
Do these games work on a phone or tablet?
Yes. They run in any modern browser on a phone, tablet, or computer, so you can play the same games on the go or at a desk without installing an app.
What is the best math game to start with?
Four Nines is the best starting point for pure arithmetic: combine four copies of the day's digit with addition, subtraction, multiplication, division, and order of operations to hit each day's target, much like the classic make-a-number puzzles. It is the daily habit at the front of the Number Lab, which also holds Four Fours (the 1881 original) and the 24 Game. From there, try WIN OR DIE for logic and deduction or Infinite Levels to explore numbers and infinity.
What kinds of math do these games cover?
Four Nines is mental arithmetic and creative equation building with order of operations. WIN OR DIE is logic, deduction, and working memory: each room states a rule, and you pick the door that survives it. Infinite Levels is lateral thinking about numbers and infinity, where number-shaped ideas become places to discover.
Are these good for practicing mental math?
Four Nines is the most direct mental math practice here, since reaching the target means juggling addition, subtraction, multiplication, division, and grouping in your head. A daily target keeps the practice short and repeatable. WIN OR DIE leans more on logic, and Infinite Levels on lateral thinking, so together they exercise a range of number and reasoning skills.
What is the difference between a math game and a math puzzle?
A math puzzle usually has one correct answer to find, like the daily equation in Four Nines or the surviving door in WIN OR DIE. A math game is the broader experience around it, including streaks, exploration, and the satisfaction of a clean solution. These three sit in the overlap: they are puzzles you keep coming back to play.
Are these games for kids or adults?
They are designed for anyone who likes number and logic puzzles, from students to adults. Younger players can practice arithmetic and rule-following, and experienced players can chase cleaner solutions, longer streaks, and the hidden corners of each game.
What if I just want the answers?
That is what the Number Lab is for: exact solvers for the four fours puzzle (the 1881 original), the four nines puzzle, and the 24 Game. Every listed solution is verified with exact fraction arithmetic, and when a target is impossible, the page says so and can prove it.
