Cornfield is an Advancedmap in Bloons TD 6. It takes place on a cornfield with several plots of crops and a scarecrow. This map features limited placeable terrain at the start, which can be expanded by spending cash to remove the patches of corn.
Bloons enter on the top left and travel down the path, exiting at the top right. The map is covered with patches of corn, with only the one in the middle removed at first. The patches of corn can be removed by spending money, with the costs generally getting more expensive the bigger the plot of land is. The corn acts as a line-of-sight blocker until it is removed. There is no water on this map.
Strategy
Despite the lack of space to start, Cornfield is usually seen as one of the easiest Advanced maps in BTD6, only bested by Ancient Portal. This is due to it being the longest Advanced map, the ability to remove corns for relatively cheap later on, and how Ultra-Juggernaut makes this map simple to complete in all game modes. Most common strategies work on this map.
If attempting "No Harvest" challenges there are 4 secret spots in which you can fit towers, on the 2nd (can fit medium towers), 5th (medium, though much tougher), and 6th bends (small, subpixel perfect), and above the third (small). These can help greatly by providing more space for defense or farming, particularily in No Harvest Freeplay challenges.
The Juggernaut balls can bounce off the corn patches repeatedly and rehit Bloons that they already hit after each bounce, making them do much more damage. If using this, remove as little corn as possible.
