The Tower Idle Tower Defense: Gem Farming & Spending Guide - Earn 400+ Gems Daily for Free

Gems move slowly in The Tower Idle Tower Defense. That is just the reality of the game. But the gap between players who hit 400 gems a day and players who barely scrape 100 usually comes down to one thing they are not hitting every source consistently, and they are spending in the wrong order when they do have gems saved up. This guide fixes both of those problems.

Where Do Gems Actually Come From

There are two types of gem sources in the game. Repeatable ones that give you gems regularly, and one-time ones that give you a big chunk when you first complete them. Beginners should focus almost entirely on repeatable sources since those are what build their daily income over time.

How to Earn 400 Free Gems Every Day in The Tower – Idle Tower Defense

Tap Ad Gems Every 10 Minutes While You Play

Every 10 minutes, a gem ad offer appears on your screen. Tapping it and watching the short ad gives you 5 gems per claim. This sounds small, but across a full day of active play, it adds up faster than any other single source. Do not ignore these. Every missed claim costs 5 gems, and you cannot get them back.

On top of that, the daily store gives you 15 free gems just for watching one ad. Takes about 30 seconds. Do it every single day without fail.

Collect Floating Gems Around Your Tower During Runs

While your tower is fighting off waves, small gems occasionally float around it. These are called Bob by the community. Each one gives 2 gems, and you can collect a maximum of 5 (10 gems total) every day.

They are spawned on an interval of about 400-500 waves or after every 15 minutes, whichever occurs first. When you are playing the game in the background and not tapping these, you are leaving behind a decent amount of free gems on the table each time you participate in this game.

Finish Your Daily Missions Every 8 Hours

Daily missions refresh every 8 hours and give you 3 gems per mission completed on top of coins and shards. The most important aspect beginners overlook is that these missions are progress-based; the difficulty of a task is proportional to the game's stage.

Most of them should not require any additional effort. Log in at least twice a day to make sure you don't miss a complete mission cycle.

Claim Weekly Rewards by Stacking Daily Missions

Each of the 5 missions per day you complete will unlock a weekly reward. Finish every 35 missions per day within a week and receive the whole weekly reward that consists of gems, coins, medals, and stones. The weekly reward can only be accessed by continuing dailies on a weekly basis. Skip two days, and the numbers drop noticeably.

Play Tournaments Twice a Week

Tournaments run twice a week and hand out gems based on where you finish in your league. Even a mid-table finish gives you something. Top performers in higher leagues can earn hundreds of gems from a single tournament. Show up, push as hard as your current setup allows, and collect the reward. It costs you nothing extra since you are just doing what you would do in a regular run anyway.

Participate in Events

Every two weeks, an event starts with specific missions. Complete these to earn Medals, which you can trade in the event shop for a one-time boost of 150 Gems.

How to Spend Gems the Right Way in The Tower - Idle Tower Defense

Earning gems consistently is only half the battle. Plenty of players save up hundreds of gems and then blow them on the wrong thing and wonder why their progress stalled. Here is the correct order.

Get the Enemy Balance Card First

Before anything else, your first gem priority is unlocking the Enemy Balance card. This card increases the number of enemies that spawn during your runs, which directly boosts the coins you earn per minute. Without it, your early game is noticeably slower. Everything else waits until you have this card in your collection.

Unlock Your Second Lab Slot Next

Labs are the biggest bottleneck in The Tower. The more labs you have running at the same time the faster your research completes and the faster you get stronger. After unlocking the Enemy Balance card, your #1 priority is unlocking all 5 Lab Slots as fast as possible. Labs are the only way to progress long-term, so don't spend gems on anything else until all 5 slots are running. Game Speed should always be your first active lab and Attack Speed follows right after it.

Add Card Slots to Run More Cards at Once

Once you have Enemy Balance, you need a slot to actually use it. Buy enough card slots to run Attack Speed, Enemy Balance, and Coins all at the same time. These three cards together make a bigger difference to your daily coin income than almost any Workshop upgrade you can make at the same stage.

Do Not Touch Workshop Respec or Bot Respec Early

Workshop Respec costs 150 gems and Bot Respec costs 300 gems per use. Do not go near either of these until you have a clear build direction and are well into mid game. Spending gems on a respec when you are still figuring out the game is one of the most common mistakes beginners make and it sets you back weeks.

Do not spend gems on Module pulls until you have all 5 Labs and at least 10 Card Slots. Modules are a massive 'gem sink' that should only be touched once your foundation is built. Use the rare modules you get naturally from boss drops in the meantime. Merge them over time and you will end up with Rare Plus or Epic rarity modules without spending a single gem.

Watch every ad gem, tap floating gems during runs, finish daily missions twice a day, compete in both weekly tournaments, and stay active in a guild. Spend what you earn on Enemy Balance first, then your second lab slot, then card slots. Leave Workshop Respec and Bot Respec alone until you know exactly what you are doing. Do all of that consistently and your gem income stays healthy for free throughout your entire time with the game.
