Three resources
Cash exists only inside a match. Bricks last forever and buy towers plus the Ability shop. Gold is spent only when you cast an ability.
Nothing converts Cash or Gold into Bricks. Clears and codes are the Brick sources.
How Cash is recorded
Cash comes from damaging enemy health, from wave rewards, and from generators such as Business Dummy. There is no kill bonus.
No Cash enemies pay nothing. Armor and shield pools pay nothing until real health takes damage.
Public notes write the co-op split, with c as Cash and h as enemy health, like this:
| Players | Recorded formula |
|---|---|
| 1 | c / h |
| 2 | c / (1.5h) |
| 3 | c / (2.5h) |
| 4 | c / (3.5h) |
Read that as a smaller share per player as the lobby fills. Solo is the fastest way to afford an expensive board. The payback calculator lets you type your own upgrade cost and extra Cash per wave. It does not know your match.
Business Dummy
Level 0, 1,200 Bricks, $225 to place. Later summaries say income climbs from $50 to $3,600 across five levels, and that each level pays for itself in about four waves. A V1.27.14 stat page listed level 5 income at $2,750 instead. If the tooltip disagrees with either number, trust the tooltip.
Caps: 12 solo, 10 with two players, 8 with three, 6 with four. Place it off the path and level the copies together.
Bricks you can actually count
| Route | Bricks | Notes |
|---|---|---|
| Noob Experiment clear | 4,750, plus 2,000 Exp | Repeatable. Hard. Matchmaking does not queue it |
| TY30kLikes | 500 | One claim. Still on October 2026 working lists |
| UndeadMode | 350 | One claim. Still on October 2026 working lists |
| Endless100Waves, SurgeonBotIsTuff | 400 each | September 30, 2026 working report. Filed expired after October 1-4 lists retired them |
| ThewNewModeNB | 350, sometimes printed as 400 | Keep the Thew spelling. Filed expired with the same October lists |
Other modes do pay Bricks. Current notes do not publish those totals.
An April 24, 2026 player video reported about 850 Bricks for Team Guest, 895 on Noob City, 935 on Baseplate Island, and 977 on Lost Island. The video's 9,250 Brick loadout of BlockDummy, Large Dummy, and Large ScaleDummy matches an older Large Dummy price of 3,500, not the later 6,000. Do not plan a V1.29.15 farm around those map bonuses.
What to spend Bricks on
Tower unlocks first. The early sequence is BlockDummy (750), Business Dummy (1,200), Dummy Base (2,500), then a level 15 splash or minigun tower. Titans run from 18,500 for Titan Noob to 92,500 for Titan ScaleDummy, and two purchases are badge-gated: MKI Titan Dummy needs The Crystals, Sphere Dummy needs Defeat Plague Doctor.
After Noob Battalion, the Ability shop is:
- Wall: 6,000 Bricks, a 1,000 HP barrier.
- Airstrike: 10,000 Bricks, 50 Gold, 50-second cooldown.
- Napalm Airstrike: 12,500 Bricks, same strike plus burn.
An older abilities note said the Wall had 1,100 HP and cost 20 Gold. Current notes publish 1,000 HP and do not publish a Wall Gold cost.
Autoskip is free with the Team Guest badge. Do not look for it in the Brick shop.
