How to play
Build an expression that equals 24 using each of the four numbers exactly once. Addition, subtraction, multiplication, division and parentheses are allowed. Every daily deal is verified to have at least one solution; after six tries you can reveal one.
About
Twenty-Four deals you four numbers each day and challenges you to combine them with addition, subtraction, multiplication and division to reach exactly 24. Every number must be used once and only once, and you may group operations with parentheses to control the order of evaluation. A new puzzle appears at midnight local time, so the same set of numbers is shared by all players for that day.
The interface shows the four numbers in a row and provides buttons for the four basic operators plus an undo control. You build an expression step by step; when the current value equals 24 and all numbers are consumed the puzzle is marked solved. If you get stuck you can reveal a hint that suggests the first operation without giving away the full solution.
How your result is scored
Your daily result records whether you solved the puzzle, how many hints you used and the time elapsed from first interaction to a correct solution. The game stores a running streak of consecutive days solved and a personal best time for each completed puzzle.
A solved puzzle with zero hints and a low elapsed time indicates strong mental-arithmetic fluency for that number set. Longer times or hint usage simply reflect the difficulty of the specific combination; the streak counter is the most reliable indicator of consistent practice rather than raw speed.
Tips to improve
- Look for factor pairs of 24 such as 3×8, 4×6 or 2×12 and see if the dealt numbers can build those factors.
- Try dividing early to create fractions that multiply back to an integer target.
- Use subtraction to turn a large number into a smaller, more useful one.
- Remember that parentheses let you add or subtract before multiplying or dividing.
- If stuck, work backward from 24 and ask which two numbers could have produced it in the last step.
