This How to AFK Farm Gems in Universal Tower Defense guide focuses on a reliable early-game method that dramatically increases your gem income compared to the AFK chamber. While the AFK chamber offers roughly 35 gems every six minutes even with VIP, this method reaches around 280 gems in the same timeframe, giving beginners a clear advantage while progressing.
How to AFK Farm Gems in Universal Tower Defense
Why This Method Works
The key difference is the ability to automate fast runs in the first Shinobi act. The stage is short, enemies are weak on the lowest difficulty, and gems scale poorly when increasing difficulty, making the base level the most efficient option. With an auto-replay macro, you turn these short runs into a continuous cycle that feeds gems at a far higher rate than passive AFK.
Preparing the Setup
Enter the Shinobi world and choose the first act. Set the difficulty to the lowest setting. Increasing difficulty only adds a small number of gems, which isn’t worth the additional time it takes to complete the stage.
Once you load in, walk toward the front of the map and tilt your camera straight upward. This prevents your recording from capturing unnecessary visual offsets that might break the repetition loop.
Creating the Automation Loop
Start your macro recording once your camera is fixed upward. Trigger the speed button, begin the mission, and place and upgrade the units you normally use to clear early waves. Rocky is commonly used in the example, but any fast early-game unit you have will work.
When the mission ends, choose replay or restart. As soon as the loading screen appears, stop the recording so the macro can return to the starting moment cleanly. This creates a seamless loop that repeats the same series of inputs without interruption.
Expected Gem Gains
Running this method continuously yields roughly 67,392 gems in a full twenty-four-hour cycle. It won’t match specialized late-game strategies, but for newer players this is an excellent way to gather large amounts of currency with minimal oversight.
While the AFK chamber provides a basic passive income, automated Shinobi farming multiplies your gem intake and speeds up early progression significantly. With a stable macro setup and a fast unit layout, beginners can secure thousands of gems every session without manual play.
