How to unlock the Challenger achievement in Bloons TD 6 - Definitive Guide
This achievement can be easy to miss early on since the challenge section is not labelled on the main menu. To find challenges you will need to click on the two monkeys with an exclamation mark over their head (NOT the co-op tab at the bottom of the screen) and from there you will find the daily challenge which you will need to complete in order to unlock this achievement.
