## What is 24++?

24++ turns the classic make-24 puzzle into a clean mathematical playground. Combine four number tiles, reshape values with exact transformations, and discover a path to 24 that feels as elegant as it is correct.

START CLASSIC, THEN GO GEEK
• Classic Lab: +, −, ×, and ÷
• Transform Lab: add square roots and factorials
• Trig Lab: use exact sine and cosine values in degrees

BUILT FOR EXPLORATION
• Tap tiles or sweep across several tiles to select them
• Combine up to four selected values from left to right (Multi-Select is on by default)
• See every expression grow without typing formulas
• Use exact arithmetic—24 is never accepted through rounding
• Reveal progressive hints or a verified worked answer
• Pick a random unsolved puzzle and continue where you left off
• Filter large puzzle banks by solved and unsolved status
• Find bookmarked and skipped puzzles together in Library
• Skip a puzzle for now and return to it whenever you like

MADE FOR IPHONE AND IPAD
• Automatic, Day, and Night appearances
• English, Simplified Chinese, and Japanese in the app
• Sync progress, bookmarks, and skipped puzzles between your devices using the same Apple Account in iCloud
• Keep playing offline; settings and in-progress calculations stay on each device
• No separate app account, ads, or developer analytics

Try 72 curated puzzles for free: 24 in each lab, using numbers 1–13. Full Lab is a one-time purchase that unlocks every available Classic, Transform, and Trig puzzle in the verified 1–13 bank, including future bank updates. Family Sharing is supported.
