In CHIMPS mode, efficiency is everything. Since you cannot sell towers or generate extra income, the “cost-to-power” ratio determines a tower’s viability. This tier list focuses on towers and heroes that consistently perform across all map difficulties, including True Expert maps.
Hero Tier List (CHIMPS)
| Tier | Heroes | Why? |
| S | Geraldo, Corvus, Sauda | Geraldo provides items for every situation; Corvus offers infinite versatility through spells; Sauda can solo the early game on many maps, allowing for massive saving. |
| A | Psi, Etienne, Obyn | Psi excels at late-game MOAB destruction; Etienne provides global Camo detection; Obyn is the king of Druid-based strategies. |
| B | Quincy, Adora, Pat Fusty | Quincy is a reliable, cheap starter for Expert maps; Adora has massive late-game DPS but is expensive; Pat offers great stuns and buffs. |
Tower Tier List (CHIMPS)
S-Tier: The “Must-Haves”
- 0-2-5 Perma-Spike (Spike Factory): The ultimate safety net. Even after balance changes, its ability to catch leaks at the exit is unmatched.
- 0-2-5 Prince of Darkness (Wizard): Incredible value for money. It cleans up Ceramics and MOABs effortlessly during the mid-to-late game.
- 2-0-5 The Tack Zone (Tack Shooter): Massive DPS for a low cost, especially when paired with an Alchemist and a Village.
- 4-2-0 Main MOAB (Sniper): Essential for stalling MOABs and DDTs, giving your other towers time to deal damage.
A-Tier: Strong Win Conditions
- 0-1-5 Avatar of Wrath (Druid): The centerpiece of the “Druid Spam” strategy; destroys Round 98.
- 5-0-2 Sky Shredder (Ace): Global damage with immense pierce, though it requires good placement.
- 0-5-2 Wizard Lord Phoenix (Wizard): High ability uptime provides massive screen-clearing power.
- 2-0-5 Icicle Impale (Ice Monkey): One of the best DDT counters in the game.
B-Tier: Reliable Support & Niche Damage
- 0-2-3 MOAB Glue (Glue Gunner): Dirt cheap and slows MOABs significantly. Almost every CHIMPS run should have one.
- 0-1-3 MOAB Press (Boomerang): Provides vital knockback against ZOMGs and BFBs.
- 0-4-0 Bloon Sabotage (Ninja): Its ability is mandatory for surviving the speed of Round 95 and Round 99 DDTs.
- 1-3-0 Druid of the Jungle: Excellent early-game carry for its price.
The “Never Buy” List (CHIMPS)
- Banana Farms (All paths): Literally provide zero value as income is disabled.
- x-x-3+ Alchemist: “Lead to Gold” and “Rubber to Gold” do not generate extra cash in this mode.
- x-x-3+ Monkey Village: “Monkey Town” and “Monkey City” do not provide bonus cash for pops.
- 0-0-5 Trade Empire (Boat): The income buff does not function.
