Dart Guideline

"See exactly where your throw will go with a guideline that adjusts as you change your aim and power. Especially effective when using maximum power."

- Upgrade description

Dart Guideline is a premium upgrade in Bloons 2 and is available in the Bloons 2 Store for free. However, if you want to get it, you must sign up for a MochiGames account. It can also be accessed by clicking the button that looks like a dart with a separated line in front of it and a red X through it (in between the reset button and the music/volume button).

Trivia

 * The actual ingame upgrade misspells guideline as "Guidline", but in the description, it is spelled correctly.
 * The Dart Guideline is very helpful for levels which you need a perfect aim to win.
 * Due to the shutdown of MochiGames servers, it is now impossible to activate Dart Guideline under normal circumstances.
