Develop basic math skills with popular Chinese
card game!

Four Cards is a popular Chinese card game that i often played as a competition, and to help students develop basimath skills. The objective of the game is to construct an equation that totals 24 using the four cards you have been dealt, and a combination of the three math operators. The numbered cards are equal to their face value, with A=1, J=11, Q=12, and K=13. The math operators available to you are: Add, subtract, multiply and Divide. Each card can only be used once but the math operators can be repeated. Only whole numbers, zero or greater can be calculated.

To play, you need to place the four cards you are dealt in the four slots, and place the three math operators between them in such a way that the resulting equation equals to 24. You can either drag the cards and operators to the desired slot or simply tap on them. Tapping a card or operator places it in the next open slot from left to right. To remove the card, or an operator from the slot simply tap it again. Four cards, has an intuitive clean interface, and full range of options. It’s a mathematical brain teaser that will test your math skills to the limit.

Let’s say for example, you are dealt the 7, 8, 8 and 2 cards. First place 7 and 8 in the first two slots and place the multiplication operator in between them. This will equal to 56. Next place the second 8 card in the third slot and place a subtraction operator between them. The equation so far equals 48. Now place the final 2 card in the last slot and place the division operator in the third slot making the final equation now equal 24. In the normal mode, you will only dealt cards from Ace to 10. The advanced mode includes face cards 11 through 13 as well, which makes it tougher to solve the equation. Four cards is a classic puzzler game that will both challenge and entertain you.
