The amount of coins you can get in your game depends on how far you can get in your run, what tier you are running on, what upgrades you have, and a host of other factors. Here is a comprehensive list of ways to help you improve your coin income.
Your Coin Multiplier
First, we’ll go through what comprises our main coin multiplier (see image), and how we can improve these:
Thereafter we’ll go through the additional things that make up our coin income, including ‣, ‣, Milestones, Card Masteries, Gameplay Strategies, and more.

Packs
So, first of all, packs. Not all are willing or capable of making purchases with real money, but if you can spend a bit - and pretend that this is the “download cost” or the equivalent of buying a console game - then it is recommended to get the packs that multiply your coin income. These are multiplicative and not additive, meaning they add up to a total of 9x more coins than you otherwise would have earned.
- Getting the Starter Pack - will give you a 2x coin income multiplier (plus 150 Gems)
- Getting the Epic Pack - will give you a 3x coin income multiplier (plus 750 gems)
- Getting the Disable Ads pack - will give you a 1.5x coin income multiplier (plus other bonuses no longer requiring ads, such as claiming Ad Gems in your run. PS! While this pack has the lowest coin multiplier, it is an important pack due to all the gems you can collect with ease without having to watch ads that interrupts your run (and thus interrupts your coin income).
Cards
Using and upgrading the following Cards will help you boost your coin income:
-
Coins Card - increases all coins you earn by a multiplier. Starting at 1.15x at level 1, and reaching 1.45x at level 7.

-
Enemy Balance Card - increases enemies spawned each wave, and cash earned per kill increased by up to 1.90x.
- Killing enemies is what earns us coins, and each enemy type has a static coin drop value that doesn’t change during your run. Basic drops 0, Fast drops 2, Tank drops 4, Ranged drops 2, Boss drops 5, Protector drops 3, Elites (Vampire, Scatter, Ray) drops 4. As a result of using the Enemy Balance card, you will be facing more enemies, which will net you more coins.

Critical Coin Card - makes basic enemies destroyed by critical damage have a chance of dropping coins of up to 33% (at card level 7).
- So, because Basic enemies by default drop 0 coins in the game, the Critical Coin card gives you a chance at earning 1 coin per Basic killed.
- PS! It is important to note that “critical damage” in this sense virtually includes all kinds of damage EXCEPT non-crit tower projectiles. In other words, for the Critical Coin card, all kinds of damage, such as Death Ray, thorns, orbs, and Ultimate Weapons (UW) damage, are considered “critical damage”. Thus, for farming, if you have space for the card, use it. If you don't have space for the card, get more card slots!

While less direct, using the Wave Skip Card and the Wave Accelerator Card will also result in some additional coin gains.
- Wave Skip Card is beneficial because it introduces a chance to skip a wave and earn coins and cash equal to the previous wave x1.10, which means both more coin income and faster runs.
- Wave Accelerator Card is beneficial because it reduces the cooldown between waves, which means you will have less downtime and more time spent killing enemies.

Modules
- Upgrade your Generator module: Every time you level up your generator, its coin bonus increases.
- PS! If you haven’t already (and have your modules at ~100+, you can also do a few quick lab levels in Module Shard Cost to get some additional free level increases on your modules, including your generator.
- Roll coin bonus Sub-Module Effect on your generator module: While not a large bonus, rolling coins/kill bonus on your generator will gain some additional coins.

An example of Generator substats.
- Use Sub-Module Effects (”substats”) on your Core that improve your econ Ultimate Weapons: Including Golden Tower Bonus/Duration/Cooldown, Black Hole Size/Duration/Cooldown, Death Wave Quantity/Cooldown, or Spotlight Angle.
