Bloons TD 5

This guide shows how much each level costs for ALL the upgrades.

Before starting make sure to purchase the Double Cash, Bigger Beacons, Healthy Bananas, FastTrack and Reverse game type

Each upgrade has 13 levels to it. In order to unlock each upgrade level, you must complete all 63 tracks on EASY, MEDIUM, HARD, IMPOPPABLE and REVERSE. In doing so you will unlock Mastery mode for each type of track (i.e. beginner, intermediate, expert). Mastery mode is a game type that allows you to replay each track, but the bloons are stronger, towers are more expensive and rewards are greater.

Upgrading everything will cost 2209 coins. This is a lot of coins, which means a lot of grinding. Once you have unlocked mastery mode I suggest doing some tracks on that game type. You can buy 5 coins at a time with $750 monkey money. This makes things go a lot faster, so save as much cash and coins as you can

If you want the super detailed version, look at the other solution. I wasn’t sure where to post this because I didn’t want to spam every achievement but here is a short description that should help.

You have to play every level on every difficulty. It’s difficult/waste of time to try and play levels on harder difficulty until you have leveled up all your towers. By the time you play everything on easy you should be close. SAVE ALL YOUR MONEY. Upgrade starting cash, lives and double cash ASAP.

After you have done every track on easy you should have enough cash to buy the special agents which you need to use each one 50 times(some exceptions). If you start a game on hard and place a meekrat, turtle, squirrel, radadactyl and bee keeper at the beginning the course, you can go to lvl 32 without losing a life. During that time add a banana farm and a banana farmer, upgrade farm to 4/2 and by lvl 32 you should have about 70k cash. The rest should be easy.
