Precision

"Get Bronze, Silver, or Gold with exact Bloon pops."

Precision is a hidden achievement in Bloons Supermonkey 2 Mobile. It rewards 100,000 Gold Blops upon completion. To get this achievement, the player needs to earn a Bronze, Silver, or Gold medal by getting the exact amount of pops needed for it.

Strategies
You'd want to earn this achievement on a very early level in the game. It is recommended to do Level 1 or 2, since bloons are less numerous. You'd want Dart Shooters on both arm slots and the Pulse Laser for the core slot to prevent any accidental area popping. Once you have the exact medal requirement pop count in the level, bring Super Monkey to one of the top corners to safely prevent any more accidental bloon pops. Don't forget you can always equip any low tiered weapons anytime!
