As of 2015, play “Bloons Tower Defense 5” on Ninja Kiwi's official website or on arcade websites that offer the game, such as Kongregate.com. “Bloons Tower Defense 5” is a tower defense game in which players have to use monkeys to pop “bloons” before they successfully make it to the end of the stage.
Gamers play “Bloons Tower Defense 5” using a computer mouse to place towers around the game board. They can also click on towers that they have already placed on the board to upgrade or sell them. As players progress through the game, they level up and unlock new towers. Each tower has its own ability, price and resell value.
Every time a bloon makes it to the end of the stage, players lose one life. If there are multiple bloons inside one bloon, then they lose multiple lives. If the player runs out of lives, the game is over.
There are several game boards that players can choose, and they range in difficulty from beginner to extreme. Players can start off playing beginner, intermediate and advanced. However, they have to grow levels to unlock more difficult boards such as expert and extreme.
After choosing a game board, players pick a difficulty setting that ranges from easy to hard. On the easiest setting, bloons move slower, towers cost less and players start off with more lives. On the hardest setting, everything costs more and bloons move faster.
