Bloons Tower Defence (BTD) is a well-known tower defense tactic that Ninja Kiwi created. The player has to use the defense towers provided in order to impede the balls, further referred to as "bloons", from moving through the game screen.
Bloons Tower Defense is a "tower defense" style of defense game whereby one has to defend an area or path from the invasion of different colored balls. Every ball will possess different abilities, and one needs to select appropriate defense towers to cope with each ball type. You can use simple towers at the beginning; you will be able to unlock more powerful towers that can attack better and deal with more powerful bloons as the game progresses.
Many different levels are available within the game; each level will have a different map and flow of balls. The balls will go through the paths that you need to protect. You will place defence towers on the indicated points on the map, so they can attack the path the balls will move by. The shooting may be performed with everything from bows to bombs, missiles, or even ice. Each tower will have its peculiarities, such as attack speed, range, power, and special effects.
Bloons Tower Defense is visually interesting and quite entertaining as a protection strategy game. Such a great combination of strategic thinking and making fast decisions.
