You have to beat 50 rounds to win this mode beating a track on this difficulty earns you a Bronze Medal for that track. Easy Difficulty: You start with 200 lives, all towers and upgrades are cheaper than normal, and all Bloons move slower than normal.Meanwhile, extensively using any particular tower type earns XP for that specific tower type, allowing you to unlock upgrades for that tower type after earning enough XP in this manner. The number of Bloons you pop overall gives you XP towards your Career Rank once you earn enough XP to level up to a higher Career Rank, you unlock a new tower type. This game also features an experience system which lets you gradually unlock new towers and upgrades by popping Bloons. Additionally, this game also introduces Bloon Properties which give the Bloons extra abilities.

Some Bloons can be popped with relative ease, but others can resist some types of attacks from your towers. Each tower type has its own method of attack, and can be upgraded to increase its lethality against the Bloons. After beating the last required round, you have the option to either return to the main menu or keep playing in Free Play mode to see how far you can get. You start out with $650 and a set number of lives depending on the difficulty level, and must use that money along with the money earned from popping Bloons to set up a solid defense using the different tower types in your arsenal in order to beat a certain number of rounds (the exact number depends on the difficulty mode chosen). The game is played on one of the many different tracks that you can choose at the start of the game after choosing a track, you get to choose the desired mode and then the game begins.
