If you're new to The Tower - Idle Tower Defense, you're in the right place! In this guide, we'll introduce you to the game and break down how to upgrade and modify your Tower by choosing from a vast arsenal of unique weapon cards, modules, and economic strategies. We will explore some of the best builds in the tower idle, and how you can farm indefinitely without keeping the game running on your mobile device, enjoying the convenience of playing The Tower - Idle Tower Defense remotely across any device with an OSLink.
Maximizing Gem Usage for Faster Progression
In The Tower - Idle Tower Defense Online, Gems are a plentiful in-game currency used to purchase both cards and modules. In matches, they spawn every 10-15 minutes, with 13 minutes being a common interval. By combining gem farming with daily missions, you can earn approximately 400 gems per day. You can earn additional gems and stones from the tournaments, which are held twice a week, offering gems, stones, and keys for progression.
How to Spend Gems Efficiently
Your first priority should be spending all gems on cards until you obtain a set of cards that can maintain Enemy Balance. This dramatically accelerates early-game progress, as the game slows down significantly without it. Once you unlock Enemy Balance, you have two main paths to choose from:
Fast Progression Path: Invest in extra card slots early to maximize progress within the first few weeks. This strategy helps you compound your gains while saving gems for unlocking labs, making it ideal for active players farming thousands of waves per day.
Long-Term Growth Path: Delay spending gems on card slots and focus on a more balanced progression aimed at late-game efficiency.
Choosing the right approach depends on your playstyle, whether you prefer a fast-paced start or a steady long-term strategy.
Ultimate Weapons Selection
There are nine different Ultimate Weapons in the game, and when selecting one, you’ll be given a choice between three random options. Make sure to choose the best Ultimate Weapon on your first try, as once you’ve selected an Ultimate Weapon, you cannot change it.
The ideal first choices are:
- Golden Tower
- Black Hole
- Spotlight / Deathwave
Each of these provides coin bonuses, which are highly beneficial for progression. If the above choices aren’t available, selecting the right weapon may require careful planning. Here are other options you can pick from.
- Spotlight: A powerful damage amplifier that works multiplicatively with other damage boosts.
- Death Wave (V24.3 Update): Recently revamped, now functioning as a Jack-of-all-trades Ultimate Weapon. It provides bonuses to Coins, Cells, and Damage. During early waves of farming runs, it spawns a Death Ring (Firewall) that lasts until its damage pool is depleted. Anything destroyed by this effect, or tagged by Effect Wave before the Ring activates, benefits from Death Wave’s bonus.
- Smart Missiles + Spotlight: These two have strong synergy through Spotlight Missiles, significantly increasing damage output.
- Inner Land Mines + Smart Missiles: This combination works well for stunning bosses, allowing Smart Missiles to land multiple amplified hits.
- Chain Lightning: A high-damage weapon with a strong chance to apply Shock, amplifying all sources of damage. When paired with Module: Dimensional Core, it drastically increases single-target damage and amplification effects.
- Chrono Field: Requires significant time and stone investment to reach its full potential.
- Poison Swamp: Provides a stun effect and extra damage output, making it a great assist for Spotlight Missiles Orbless Devo builds.
Optimizing Your Lab for Maximum Progress
In The Tower - Idle Tower Defense, you can unlock up to five laboratories using gems. These labs allow you to research permanent upgrades that enhance base stats, cards, modules, and even Ultimate Weapons. Since these upgrades play a vital role in progression, prioritizing the right research is essential. However, because research takes time, your upgrade choices should align with your build and playstyle.
While this guide provides a general upgrade path, remember that the ultimate goal is to enjoy the game and adapt based on your needs. Here’s how to make the most of your lab slots:
- Slot 1: Game Speed – Max this out as soon as possible. Once completed, prioritize Attack Speed (at least level 50) and keep upgrading it nonstop.
- Slot 2: Lab Speed – A flexible choice. Early on, when research times are short, you may use this for quicker labs. Once labs start taking days to complete, focus on permanent Lab Speed upgrades, especially HP and Damage labs.
- Slot 3: Economy Upgrades – Dedicate this slot to boosting your economic efficiency for a few weeks or months.
- Slot 4: Second Economy Slot – Further increase your farming potential by doubling down on economic upgrades.
By efficiently managing your lab research, you can maximize your Tower’s growth and long-term efficiency.

Orb Devo Build for Maximizing Coin Farming
The Orb Devo Build is a specialized coin-farming strategy, particularly effective in early waves. It maximizes earnings before transitioning into other builds.
Core Setup:

Tips: Ideal for players looking to farm resources efficiently before shifting to damage-oriented builds.
Optimizing Your Farming Setup with OSLink
Each of these builds serves a different purpose, but none of them can be perfectly automated to run for 7 to 8 hours without supervision. Keeping the game open on your mobile device means you can’t use your phone for anything else, which can be inconvenient.
That’s where OSLink comes in. By installing it on both your PC and mobile device, you can run the game on an emulator, keep it running while you're away, and check in on your progress from your phone anytime. This lets you make adjustments without keeping your phone occupied, making resource farming more efficient.

Tips: To ensure a smooth, uninterrupted farming setup while AFK, reduce the game speed to 1x, resulting in around 800 waves over 8 hours. If set to 2x speed, it will reach 1,600 waves in the same timeframe. This method allows you to disable auto-perk, letting you manually pick perks and upgrade tabs when you have time to play at full speed.
