Quick Reference
The build at a glance
Half Cash is the economy challenge. You start with the same $650, but every bloon popped pays half and every Banana Farm pays half. You can never have enough money.
The strategy: delay everything. Buy cheap towers, save every dollar, and only upgrade when absolutely necessary. Spike Factory is the meta — Spikes don't cost money per spike, they generate over time.
Step by step
Gwen's heat-it-up gives you damage for free, which is what you need when you can't afford upgrades.
Place a 0-0-0 Dart Monkey. Don't upgrade. Save every dollar.
Add a 0-0-0 Bomb Shooter to 1-0-0 (Bigger Bombs) by round 24. Bare minimum for ceramic rush.
Place a 0-0-0 Spike Factory to 2-0-0 by round 35. Spikes are your main DPS — they generate for free.
Add 0-0-0 Tack to 0-2-0 (Faster Shooting). Save aggressively for...
3-0-0 Spike Factory (MOAB Press) by round 70. This is your MOAB killer.
Spike to 4-0-0 (Spike Storm) by round 95. Use Gwen's level 20 ability on round 100 BAD.
Spike Factory generates spikes for free over time. In Half Cash, this is huge — you don't need to spend money on every spike, you just wait. The 3-0-0 (MOAB Press) and 4-0-0 (Spike Storm) are the strongest MOAB damage in the game per dollar.
Common mistakes
- Buying Banana Farms. They earn half, so they're terrible here. Skip them.
- Upgrading too fast. The whole point of Half Cash is patience.
- Ignoring the Spike Factory. It's the only tower that scales well with limited cash.
