The classic 24 game. Combine all four numbers with +, −, ×, ÷ so the last one left is exactly 24. Every hand is solvable — how many can you crack in 90 seconds?
Four numbers appear. Tap one number, tap an operator, then tap a second number — the two merge into a single result, leaving you one number fewer.
Keep combining until just one number remains. If it is exactly 24, you score and a fresh set appears. The order you pick matters for − and ÷ (the first number tapped comes first), and results can be fractions along the way, which is often the key to a tricky hand.
If you back yourself into a dead end, tap Reset to restore the four starting numbers and try a different route. Every hand is guaranteed to have at least one solution.
You have 90 seconds. Your score is how many hands you make 24 from, so find the path quickly and move on.
Learn the handful of pairs that already make 24, and scan for them first: 4×6, 3×8, and 2×12 are the backbone of most hands. The moment you see a 4 and a 6, or any way to build an 8 to pair with a 3, you often have the whole solution in one glance.
When no clean product jumps out, work backwards from 24. Ask what two values, combined, give it: 24 is 20+4, 30−6, 48÷2, and so on. Then treat the rest of your numbers as raw material for building one of those two targets, which turns a vague search into two much smaller ones.
Do not fear fractions — they are often the only road through a stubborn hand. The famous 3, 3, 8, 8 is impossible with whole numbers but falls instantly to 8 ÷ (3 − 8÷3). Whenever the integer routes dry up, deliberately try dividing first to create a fraction that later multiplies back up.
In the timed mode, speed comes from pattern recognition, not brute force. If a hand does not resolve within a few seconds, reset and re-read it from scratch rather than grinding a dead line — a fresh look at the same four numbers very often reveals the 4×6 or 3×8 you walked straight past.
