Early-game = Rounds 6-40
Mid-game = Rounds 41-60
Late-game = Rounds 61-80
General tips
Preparation
- When attempting ABR, it is recommended that many Monkey Knowledge upgrades have been acquired. Important Monkey Knowledge upgrades include Bonus Monkey!, More Cash, Mana Shield, Military Conscription, and Veteran Monkey Training. With Monkey Knowledge, following the tips given here becomes much easier.
- To obtain the Monkey Knowledge upgrades, it is recommended to beat Hard Standard on a good amount of maps before touching ABR. That game mode grants large amounts of Player XP for Monkey Knowledge points, is relatively simple to complete, and builds some experience needed for ABR.
- Remember the rounds in ABR that stand out in difficulty, which are listed below.
The most challenging rounds in Half Cash
| Round # | Bloons spawned | Reasoning |
|---|---|---|
| 40 | The fortified MOAB is the hardest challenge of the early game, having double the HP of a normal MOAB. Without a well-rounded defense with very strong single-target damage options and towers for the Ceramic insides, the fortified MOAB can end a run completely. |
