About Make24

The 24 game is a mental arithmetic puzzle: take four numbers and use +, -, x and / to finish on 24. Make24 turns it into one numbered puzzle a day. You tap a number, choose an operation, then tap another number, and the result replaces the two you used. Keep combining until a single 24 remains. Every starting number has to be used exactly once, and division only counts when it gives a whole number.

The timer starts on your first tap. The app records your solve time, streak, fastest and average times and a history of past puzzles, and you can compare times on Game Center leaderboards and earn achievements. A share button posts your result without giving away the route. If you missed yesterday's puzzle, you can reveal its solution and see the steps.

The developer's site says everyone gets the same four numbers each day, and each daily puzzle is chosen to have at least one valid route to 24. Make24 is made independently by Stuart Malcolm and came to the App Store at the end of 2025. It is free with ads, with optional ad-free subscriptions and tips.

How to play Make24

1. Open Make24 to see the day's four numbers and the puzzle number.
2. Tap a number, choose +, -, x or /, then tap a second number; the result takes their place.
3. Keep combining until only 24 is left, using each starting number once.
4. Use Undo or Reset to try a different route; division must give a whole number.
5. Share your result or check your time on the Game Center leaderboard.

Tips

• Work backwards from 24: look for pairs that make 3 and 8, 4 and 6, or 2 and 12.
• Your first move changes every option after it, so if a route stalls, undo one step rather than starting over.
• Subtraction is useful for building a small helper number such as 2 or 4.
