【實用解謎app】The 24 Game|最夯免費app-綠色工廠好玩App

How to play:

The goal is to make the number 24 using all four numbers on the card. You can add, subtract, multiply or divide. Each number can only be used once and there is at least one solution for each card (most cards have multiple solutions).

When the game starts four numbers appear on the yellow wheel. Touch on the first number, then slide your finger to the next number, then select the desired operation (+ – x ÷). The interface is flexible so you can, for example, choose all numbers and add all of them.

Continue play in this manner until you solve the card. There are three levels of difficulty showed by the stars in the center of the cards — 1 star cards are easy, 2 star cards are medium and 3 star cards are hard. If you can't solve a card you can use the skip button in the top right corner. This will put the current card on the end of the cards queue.

Tactics:

- Choose one number on the card and turn the other three into the number you need. For example: If you have a 4, try to make a 6, 20 or 28 with the rest of the numbers.

- Look at the numbers not as four independent numbers, but as two pairs. For example: On the card 5, 7, 7, 9. Pair the 5 & 7 (add) as a 12, and the 9 & 7 (subtract) as a 2, so 12 x 2 = 24. Common patterns that make the target number 24 are 6 x 4, 8 x 3, 12 x 2, 24 x 1.
