To redeem coupon codes in Coop TD: Together, open the in-game settings menu, locate the designated code input field, and enter your code exactly as provided. Make sure not to include any leading or trailing spaces, as additional characters will cause the redemption to fail. If a code fails to work, it has likely expired or reached its maximum global redemption limit.
How to Earn Free Gems Daily
Gems are the primary premium currency in Coop TD: Together, used for high-tier unit summons and permanent tower upgrades. Free-to-play players can build a steady gem reserve through a few daily activities:
- Daily Shop Offers: Check the shop every day for free gem rewards and rotating free claimables.
- Daily Missions: Complete your daily mission objectives to earn a combined payout of gold, gems, and account experience points.
- Milestones and Updates: Watch official developer social channels and community forums for newly announced promotional codes released during updates or community events.
If you hit a progression bottleneck on a difficult wave, check your active mission list first. Clearing lower-tier missions provides the quick capital required to purchase key upgrades without paying real currency.
Smart Gem Spending and Upgrade Strategy
Because gems are limited for F2P players, spending them efficiently prevents unnecessary bottlenecks in later stages.
- Avoid Temporary Boosts and Cosmetics: Do not spend gems on short-term combat boosts or cosmetic items that provide minimal combat value.
- Prioritize Permanent Upgrades: Save your gems to unlock high-tier unit summons and permanent stats for your core defensive units.
- Specialize a Core Roster: Instead of spreading gold and gems across every available unit, focus your resources on a core squad of high-performing towers. Leveling up a smaller, focused lineup lets you handle harder content with fewer total units on the field.
Balancing Tower Types and Map Placement
Pair smart resource management with tactical positioning on the field to survive incoming monster swarms and boss waves:
| Tower Category | Primary Function | Operational Role |
|---|---|---|
| Area-of-Effect (AoE) | Crowd Control & Swarm Clearing | Position at chokepoints and intersections to damage multiple enemies at once. |
| Single-Target | High Boss Damage | Place along straight paths or near main bottlenecks to melt high-health targets. |
Placing towers directly near enemy spawn points helps clear weak early waves fast, but it can leave your defense vulnerable if those towers lack the damage to handle high-health late-game enemies. Position your core damage units around map chokepoints or intersections to maximize range coverage and maintain control over the wave flow.

Nice guide. I am checking the other Coop TD: Together articles next.
Can you add more details about redeem codes in a future update?
This guide answered the exact question I had.
I tried this today and it worked better than my old setup.
