Your objective in this Bloons Tower Defense game is to place monkeys around the maze to defend from the onslaught of the moving balloons. As you get more money you can buy new towers or upgrade existing ones. Use YOUR MOUSE to click on the tower type you want to build on the right side of the screen, then once its selected, place the tower in the maze. Press escape to deselect or cancel your current action. You can sell towers for extra money for 80% of what you paid for them. There are several types of bloons. Larger and faster colored bloons have smaller bloons inside them. Can you beat all 50 levels? Good luck!
