This is a very challenging tower defense game with a unique Bloons twist. Buy and upgrade your balloon popping towers in order to prevent the balloons from escaping the maze.

You goal is to pop all the balloons before they can complete the maze and escape. You have to complete all the levels and can only allow 40 balloons to escape if you want to beat the game.

Hover your mouse over the various tower icons, in the upper right corner of the game area, to see their properties and cost.
To place a tower, click on the icon of the tower you want to buy, then move to spot on the board that you want to place the tower and left click. Try to place your towers so that they cover as much of the maze path as possible.
Upgrading towers is very important. Click on one of your towers and you will see the upgrades that are available. It is usually a good idea to upgrade towers as soon as possible, if the upgrade is actually useful.
You can sell towers for 80% of their cost. Click on your tower and an option to sell it will be displayed in the lower corner. Click this option if you choose to sell a tower so you can upgrade to more expensive towers.

When you have all your towers placed and upgraded, click the Start Round icon in the bottom right corner. You will earn points for each balloon that you pop as well as bonus points for each completed level.

This is a tough game. Try different strategies and see how far you can get.
