Double Cash Mode (BTD6)

For Double Cash Mode in general, see Double Cash Mode.

Double cash icon

Double Cash Mode is an extra in Bloons TD 6 unlocked via in-app purchase. It doubles the amount of cash the player obtains from popping Bloons, finishing a round and also the starting cash but it does not affect cash obtained by some income methods. This mode can only be obtained by purchasing it from the Shop for $17.99 USD.

Double Cash Mode is disabled in CHIMPS, Race Events, Contested Territory, Rogue Legends, Boss Challenges in Battle Mode, Boss Bloon Events in ranked mode, or Boss Rush. It can also be disabled with challenge rules, such as in the Challenge Editor.

Mechanics

While this mode is active the standard cash icon shown in the UI will be changed for the Double Cash icon. It doubles the starting cash in all game modes where is allowed, for a total amount of $1,300 in standard game modes or $40,000 in Deflation. It stacks with More Cash (giving $400 extra instead of $200) or Fast Track Mode.

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%

In Sandbox, it will also double the amount of starting cash ($19,999,998) and will be active during the testing, however the regular cash icon will be shown. When active in Half Cash, it will almost convert it in a game of Hard standard, with a few exceptions for income generation methods that aren't affected by Double Cash. In Co-op mode, the Double Cash will also apply after the cash is divided between players and will only affect players who have the mode enabled.

Cash Drop

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, a couple of examples are given below:

• 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, then doubled.
• 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 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.
