Range is the dark circle around the Dart Monkey.

Monkey Sub Line of Sight

The trees are blocking the line of sight of this Monkey Sub.

Range is a game mechanic in the BTD series. It is the limit of where a tower can detect bloons to attack. It is signified by a dark circle around towers. Contrary to popular belief, the range is not the limit of where it can attack but the area where it can detect bloons to attack.

Certain towers and upgrades have infinite range like Sniper Monkeys, Mortar Towers, Aircraft Carriers and Dartling Guns. For the Banana Farm however, the range is how far it will deploy bananas.

A very important tip is to make the dark circle touch the track's path. If this wasn't made, the tower won't be able to attack Bloons. The exceptions are towers with infinite range. For these towers, you will not have to worry about them not attacking Bloons, so feel free to place them where ever you like. There is an exception though, in BTD6.

In Bloons Tower Defense 6, a tower's range can be restricted by sight-blocking objects in the track, by a feature called "Line of Sight". This applies to both limited range towers and infinite range towers. For example, if a bloon is in a Super Monkey's range circle, but the bloon is behind a rock and the tower can't "see" it, the Super Monkey won't attack the bloon. Areas where sight is blocked in BTD6 are colored red.

The range circle for towers can be turned off in Bloons Tower Defense 6 by the "Line of Sight" option, for performance purposes. This is the only BTD game that has this option. This option has however since been removed.
