Math Playground FUN is a free math game available on the iPhone platform. Designed by KHOAT DUONG VAN, this game offers a fun and challenging way to improve your math skills.

The game consists of four lessons, each with its own unique gameplay. In Lesson 1, you use your fingers to select successive cells with ascending values to remove them from the table. Be careful though, as selecting wrongly more than 3 times will end the test. Lesson 2 follows a similar concept, but this time you select successive cells with the same values to remove them.

Lesson 3 introduces a new challenge where you help a monkey choose its hook by selecting the number or expression value in the table that matches the numerical value or expression written on the hook. Finally, in Lesson 4, you are presented with four answers in a box and you must choose the one that matches the given results. Selecting the wrong answer more than 3 times will end the test.

With its engaging gameplay and various math exercises, Math Playground FUN provides an entertaining way to enhance your math skills on the go. Whether you're a student looking for extra practice or an adult wanting to sharpen your math abilities, this game is worth a try.
