Bloons Tower Defense 3 has been largely upgraded since Bloons Tower Defense 2. It's packed with more new tracks, and balloons have also been enhanced--they now include large balloons with smaller ones inside, and a surprise balloon at the end of the game (which you must destroy with every weapon you have amassed). But the object of the game is still the same as in the first version: you have to stop balloons from leaving the track using your items, as well as help from monkeys.

Once the game loads, you must select a track you want to play with. They are all different in shape and size. After you choose the track, you will be asked to pick a difficulty level. Then, you are directed to the game session.

Before you begin, you must select the "Towers" that will protect you from balloons. If you hover your mouse over them, you will see a description of what the item does, and also the cost. To start off, you are given 650 dollars to buy your first weapons. After that, you will make your own money by destroying balloons. Choose your weapons wisely, or you will not make enough money to survive another round.

Each item on the top two rows can be upgraded for more distance, range and speed. The upgrades are a must because at the end of every round the amount of balloons increase as well their speed and power.

• Buying a Tack Shooter will give you a big foothold in the game.
