How to play

Four numbers. Make 24.

  1. 1Given four numbers, the goal is to get to 24
  2. 2All four numbers must be used, and each used only once
  3. 3Addition, subtraction, multiplication, and division can be used multiple times

Whole numbers only: subtraction always takes the smaller number from the larger, and a division counts only when it comes out even.

Previews

See the move before you make it.

Pick a number and an operation, and a small preview under each of the other cards shows what you would get. Tap one to combine the two, and keep going until a single card reads 24.

Level 3: 10 ÷ 5 = 2, then 7 × 2 = 14, then 14 + 10 = 24.

Classic

Classic lays 10,000 puzzles along a winding path. Solve one to unlock the next, all the way from Level 1 to the end. Every one of them works out in whole numbers: all 10,000 were checked.

90 seconds. How far can you go?

Each puzzle gets 90 seconds, and the clock starts over with every solve. Each solve is a point, and your best score is kept. Stuck when time runs out? The game shows you the solution.

Hints

A nudge, not the answer.

You start with three hints. A hint shows the first step of a solution; the rest is up to you. More hints are an in-app purchase that fills the bulbs back up.

Stuck for 30 seconds? The hint bulbs give a little shake.

A puzzle a day, on your wrist.

The Puzzle of the Day is one of the 10,000, on a 2 × 2 board with the same rules and previews. Survival comes along too, with its 90-second clock. It works without your iPhone, and a complication puts the day's puzzle on your watch face.
