The player must just pop the bloon closest to the monkey as well as a Tack Bloon next to the monkey to complete the level. This will set off a chain reaction, popping every single bloon on screen, giving you 100% pops.
Trivia
This level has the smallest pop percentage required in the whole game, at less than 20%. However, one shot to one of the Tack Bloons will set off the chain reaction, giving you 100% pops. This means that it is practically useless to use more than a dart to complete this level. By some players, it is known as one of the easiest levels in the game.
As soon as the chain reaction begins, the Dart Monkey will disappear and there is a message in the background that says "Game completed! Congratulations thanks for playing Bloons!".
The End is the only level in the original Bloons game to not use the sky background.
