Round 14

Round 14 is a round introduced in Bloons TD 5, which also returns in Bloons TD 6. It is characterized by a "cluster chaos" type round, where many densely packed bloons spawn on the player.

Description
Round 14 spawns a constant wave of red bloons at first, then sends a group of 5 blue bloons, then 5 green bloons, then 4 yellow bloons, then a very dense pack of 10 blue bloons, 5 more green bloons and 5 more yellow bloons.

Strategy
This is pretty much a "preparation" round on "cluster chaoses". It is considered the first "cluster chaos" round. You can deal with it with towers with large AoE (area of effect) damage, such as Mortar Monkeys and Bomb Shooters. Towers that have pierce are also a viable option.

Tips

 * Bomb Shooters and Mortar Monkeys are a good choice, as they can not only deal with the red bloons, but also can deal with the other bloons, given that they have enough support.
 * Towers that have 1 pierce such as Sniper Monkeys are not a good option (except Shrapnel Shot and Bouncing Bullet), as they cannot deal with the rush of bloons.
 * Submarines are also a viable option if the map has water present, due to their pierce.
 * Triple Shot Dart Monkeys can also thin out the crowd of bloons. Groups of them are very effective at popping bloons. If one or more has different targeting priorities, especially strong, so it can be even more effective.
