The cute pickle puppy is hostage to a complex labyrinth and will not be able to get out of it. If you don't help him in MathPup Math Adventure 3. It will take not only your dexterity with which the hero will overcome obstacles. It's important to find the key to advance to the next level, and it will only appear after you've solved the series of math problems in the top left corner. You must find the missing number. They are on platforms in the form of yellow cubes with a number on the sides. Find the cube you need, bring the puppy to it and make him jump to take it. If the number is incorrect, you will have to replay the MathPup Math Adventure 3 level.
