Double Cash Mode (BTD6)
Double Cash Mode is an extra in Bloons TD 6 that doubles starting cash and any cash the player earns from popping Bloon layers, completing rounds, and certain towers. This mode is only obtainable by purchasing it from the Shop, and is unobtainable in Bloons TD 6+ and Bloons TD 6 NETFLIX.
Double Cash Mode is disabled in CHIMPS, Sandbox, competitive events (Race Events, Contested Territory, Boss Bloon Events in ranked mode), Boss Challenges in Battle Mode, Boss Rush, and Rogue Legends. It can also be disabled using challenge rules, such as in the Challenge Editor.
Mechanics
While Double Cash is active, the standard cash icon shown in the UI is replaced with the Double Cash icon. It doubles the starting cash in all gamemodes in which it is allowed, for a total of $1,300 in standard game modes or $40,000 in Deflation. It stacks with 
More Cash (giving $400 extra instead of $200) and Fast Track Mode. Towers that indicate the total generated income next to the pop count won't track the extra cash.
It also doubles the amount of cash obtained per pop, and is affected by the cash reduction that is applied by the game after Round 51:
| Start round | End round | Relative cash per pop |
|---|---|---|
| 1 | 50 | 200% |
| 51 | 60 | 100% |
| 61 | 85 | 40% |
| 86 | 100 | 20% |
| 101 | 120 | 10% |
| 121 | - | 4% |
When active in Half Cash, Double Cash effectively converts it into a Standard Hard game, with a few exceptions for income generation methods that are not affected by Double Cash.
In Co-op mode, Double Cash applies after the cash is divided between players and will only affect players who have the mode enabled.

If multiple cash bonuses are stacked and at least one of them is affected by Double Cash, it will be the last to apply and will only be applied once, while the rest of the income is calculated as normal:
- If a Sun Temple with maximum Support sacrifices is in the range of a Monkey City Village it would produce a total of $12,000 at the end of the round, this is $5,000 base +20% from Monkey City for $6,000, then doubled. A True Sun God in this case would produce $12,000 twice.
- In the previous example, if a Lead to Gold Alchemist pops a Lead Bloon in the range of both the Temple and the Village, it would produce a total of $192, to calculate this, first, in a regular game before Round 51 the income would be $23 base for RBE of the Lead Bloon, +50% twice for Monkey Town and Sun Temple cash per pop bonus (they stack additively), resulting in $46, second we add $50 from the Lead to Gold bonus, and finally these $96 would be doubled by the Double Cash mode.
