- Keep the order. Use all four digits from left to right, each exactly once.
- Join or operate. Put + − × ÷, a power (^) or a square root (√) between digits, or join neighbours together — 2 and 6 can be 26.
- Hit the target. Press = when your equation equals the target. In Daily Digits, three correct answers earn three stars.
Example: digits 2, 6, 9, 2 and target 27
26 + √(9) − 2 = 27
Tips from Digi
- Spot the squares. 4, 9, 16, 25 and 36 turn into neat whole numbers under a square root.
- Check what divides. Look for a number that divides cleanly by the digit after it.
- Start negative. An equation may begin with a minus sign, which is often the key to small or negative targets.
- Powers of 0 and 1. Anything to the power of 0 is 1, and 1 to any power is still 1 — handy for using up spare digits.
- There is usually more than one answer. If your first idea is stuck, try a different grouping.
Why a daily maths puzzle?
A few minutes of mental arithmetic each day is a simple, satisfying way to keep your number sense sharp. Daily Digits exercises order of operations, estimation and flexible thinking — the same skills behind quick everyday sums — and it is the same puzzle for everyone, so you can compare scores with friends and family.
The game began as a classroom challenge: take the digits of the year and make every number from 1 to 30. That idea lives on as Yearly Digits. Read the full story on the about page.
Frequently asked questions
How do you play Daily Digits?
You are given four digits and a target number. Use all four digits, in the order shown, with any mix of + − × ÷, powers, square roots and brackets to make the target. You can also join neighbouring digits, so 2 and 6 can become 26.
Is Daily Digits free?
Yes. All three game modes are free to play in your browser with no download. A free account lets you post scores to the leaderboard, keep a streak and save your Yearly Digits progress.
When does the new puzzle come out?
A new set of three daily targets (easy, medium and hard) is released every day at midnight, server time. A countdown to the next puzzle is shown once you finish.
How is the daily score worked out?
Your score is based on how quickly you earn all three stars. A finished puzzle scores between 600 and 1050 points. Each hint you use takes 50 points off that day’s score.
What are hints and how do I get more?
A hint first shows the shape of a solution with the operators hidden; a second hint reveals the full solution. You start with three hints, earn one for every seven days of your daily streak, and can watch a short ad at any time to earn another.
What is Yearly Digits?
Yearly Digits uses the four digits of a year, such as 2, 0, 2 and 6. Your goal is to make every whole number from 1 to 30. Find 80% of the numbers that are possible to unlock the previous year, and find them all to earn a gold star for that year.
