If you want to farm gold All Star Tower Defense X efficiently, understanding the best methods is crucial. Gold is the currency used to purchase exclusive items in the Gold Shop and emotes in the Emote Shop. With the right approach, you can maximize your gold income quickly—without slowing down your team’s progress or sacrificing strong units. This guide covers the fastest gold farming strategy, how to use auto-sell settings, and which units to sell or keep for the best results.
Why Gold Matters in All Star Tower Defense X
Gold is an essential resource in ASTDX, letting players unlock special items and unique emotes that are not available through other currencies. However, traditional gold farming methods such as Story mode or Challenge mode are very slow and not recommended if your goal is to earn gold quickly.
The most effective way to get more gold fast is to take advantage of the summon and sell strategy. By focusing your efforts on unit summons and selling unnecessary units, you can rapidly increase your gold supply for any exclusive item you want.
Efficient Gold Farming Methods – Summon and Sell
The core of efficient gold farming in All Star Tower Defense X is simple:
-
Collect as many Gems as possible through gameplay.
-
Use your Gems to perform summons, bringing in new units.
-
Sell the units you do not need—especially three-star units—to receive gold.
-
Repeat the process for continuous income.
The “Auto Sell” feature in the game’s Settings menu is essential for this strategy. By activating Auto Sell, all low-rarity units you obtain through summons are automatically sold for gold, saving you time and keeping your inventory clean.
Best Units to Sell for Gold – Three-Star Farming Guide
The majority of your gold will come from selling three-star units, as they are the most common outcome from each summon. Always prioritize selling these units—they are your most stable and consistent source of income.
Four-star units, on the other hand, should be sold selectively. Keep any four-star unit that has strong abilities or value for your team. Only sell four-star units when you’ve acquired a direct replacement, such as the “Ramen Grow Master” or a stronger character.
Five-star units are extremely rare and are the most powerful additions to your team. Never sell five-star units—they are vital for team strength and late-game progress.
How to Use Auto Sell Settings for Fast Gold
To maximize your gold gain and avoid unnecessary manual sales, enable the Auto Sell settings in your menu. This feature ensures that every low-rarity unit gained from summons is instantly converted to gold. It streamlines your farming process and allows you to focus on collecting Gems and summoning more units.
If you’re unsure which units are being sold, check the Auto Sell filters in Settings to confirm which rarities are included. Adjust these settings as needed to match your current farming and team-building goals.
Summon and Sell Cycle – The Most Efficient Gold Loop
The fastest way to farm gold is to follow this simple cycle:
-
Farm Gems through missions or events
-
Use all Gems on summons
-
Auto Sell or manually sell three-star units for gold
-
Review your four-star and five-star units—sell only if replacements exist
-
Repeat for ongoing gold gain
This loop can be repeated as often as you have Gems available, and is much more efficient than grinding gold through Story or Challenge modes.
Final Thoughts
To farm gold All Star Tower Defense X quickly, focus on collecting Gems, summoning as many units as possible, and selling unnecessary three-star units using the Auto Sell feature. Avoid selling four-star units unless you have a strong replacement, and never sell five-star units since they are the rarest and most powerful. This summon-and-sell strategy will help you build up gold for exclusive items and emotes in the shop, while keeping your team strong for every challenge ASTDX offers.
