All Ten

All Ten is a daily math puzzle where your mission is to use four given numbers, each exactly once, to make every whole number from 1 to 10.

Each day brings a fresh set of four numbers and a row of ten targets. Combine your numbers with addition, subtraction, multiplication, and division until you hit a target, then move on to the next. The twist is that the rules are generous, so there is usually more than one way to get there.

• Use all four numbers exactly once for every target.
• Add, subtract, multiply, and divide to build your equations.
• Fractions and negatives are fair game.
• Multi-digit numbers are allowed too, so you can join two digits together to make a bigger number.
• Your goal is to fill in all ten targets, from 1 up to 10.
• Finish and copy your results to share with friends.
• A new set of numbers arrives every day.

Why we like it:

• ✅The open rules reward creative thinking, since the neat trick behind one target often unlocks another.
• ✅Ten small puzzles in one, so there is always a next target to chase when you get stuck.
• ✅Easy to learn, with plenty of depth for number lovers.

Hint: Don't forget that you can glue digits together (tap 2 and 4 to make 24). Turning two small numbers into one big one, or dividing to create a fraction, often cracks the targets that seem impossible.
