Battle Score (), otherwise known as Battle Points, are the player's points in Bloons TD Battles. They are needed to unlock new towers, with new towers being unlocked at 50, 250, and 500, respectively in Bloons TD Battles Flash. In BTD Battles Mobile, however, unlocking towers and their respective tier-3 and tier-4 upgrades varies depending on the type of tower and their upgrade powers. 10 is awarded to the player for a win, and 2 for a loss.
In BTD Battles Mobile, however, purchasing towers, their tier-3 upgrades, and their tier-4 upgrades are required to get the most of the use of towers. In this game, every tower, their tier-3 upgrades, and their tier-4 upgrades have different costs and Battle Score requirements.
