Bloons Tower Defence Battles should not be mistaken as the version on coolmathgames because this version is a mobile app. In this version you play against another player and you choose 3 monkey towers with one bonus tower to take with yo to use in the match. In all BTD games there are bloons which you have to pop using the towers you have placed down. All towers have 8 upgrades but you can only take one. The first two upgrades on both paths are available to buy even if you brought the other four on the other side. For example the first two upgrades on the left for the ninja monkey are Ninja Discipline and Sharp Shurikens. If I buy those I’ll still be able to get the first two on the right which are Seeking Shuriken and Distraction. But if then I buy Double shot (Left) I won’t be able to get flash bomb (Right) and Sabotage Supply Lines (Right) upgrades but I will be able to get Bloonjitsu which is the final upgrade on the left. The towers you can get are: Dart Monkey, Super Monkey, Ninja Monkey, COBRA, Monkey Sub, Monkey Buccaneer, Spike Factory, Dartling Gun, Ice Tower, Tack Shooter, Boomerang Thrower, Bloonchipper, Bomb Tower, Sniper Monkey, Monkey Apprentice, Glue Gunner, Monkey Enginneer, Heli-Pilot, Mortar Tower, Monkey Village, Banana Farm, Monkey Ace, Pineapple, Road Spikes And Farmer Monkey.
