This original game of strategy tower defense offers a wide range of tracks, several levels of difficulty with a sandbox mode for training. The originality consists in the fact that are bloons to burst before they reach the exit and that towers are throwing darts or boomerangs. A button "Fast Forward" speeds up the turn. Multiple options can change the game.
Select the track you want then the difficulty. Buy your towers from the side bar on the right, then place them around the track to maximize their effectiveness. You will unlock new tower types with every rank you go up.
