Summon Heroes is one of those games where free codes genuinely matter. Gems are slow to earn on their own, and every summon ticket you can grab for free is one more shot at pulling a strong hero without spending Robux. We track codes here daily so you never miss one — bookmark this page and check back whenever a new update drops.
Right now there are a handful of active codes worth redeeming immediately. We have also listed everything that has expired so you know not to waste time on old ones. Scroll down, grab the codes, and get back to building your team.

We check this list every day. If a code stops working we move it to the expired section below. If you spot one that no longer works, drop a comment so we can update faster.
Expired Codes
None of the codes released so far appear to have expired yet, which means everything in the table above should still work. That said, the developers have not made any promises about how long codes stay live. Redeem all of them now just to be safe.
We will move codes here the moment they stop working.
How to Redeem Codes
Redeeming codes in Summon Heroes is done entirely inside the game world — there is no menu button for it. Here is where to go:
- Launch Summon Heroes on Roblox and load into the main lobby.
- Look for the Item Codes area. It is a glowing circle on the ground, located to the right of the Summon circle and to the left of the Item Shop.
- Walk your character into the circle. A text box labeled Enter Code will appear on screen.
- Type the code exactly as it appears in the table above. Codes are case-sensitive, so do not lowercase anything or add extra spaces.
- Confirm the code. If it is valid, your reward lands in your inventory immediately.
That is the full process. You cannot redeem codes from the website or from any external tool — it all has to happen in-lobby.
What Is Summon Heroes?
Summon Heroes is a gacha-style tower defense game developed by RedManta LLC on Roblox. The core loop is simple: you pull heroes through a summon mechanic, build a team, and send them out to fight waves of enemies across a series of story worlds.
The game currently has more than 20 heroes to collect, each sitting at a different rarity tier. Higher rarity heroes are obviously stronger, but building synergies between your lineup matters almost as much as raw stats. You progress through story chapters, unlock harder difficulty modes like the Nightmare Circus, and test your roster in PvP against other players.
Currency comes from completing stages, daily quests, achievements, and opening chests scattered around the map. Gems are the premium currency used for summons. Heroes you do not want can be sold off for resources, which takes some of the sting out of bad pulls.
The game launched in beta and has been growing steadily ever since, with the Lv 100 update being one of the bigger content drops in recent months. If you are into games like Anime Vanguards or All Star Tower Defense, Summon Heroes fits right into that same genre — check out our Anime Vanguards Codes page if you play both.
How to Get More Codes
The developers drop new codes when the game hits player milestones, during major updates, and for holidays or special events. Here is where to watch for them:
- Official Discord — This is the fastest source. Developers post codes in the announcements channel as soon as they go live. Search for the Summon Heroes Discord server through the game page on Roblox.
- Twitter/X — The RedManta LLC account posts milestone codes whenever the game crosses a big concurrent player count or total visit number.
- Roblox Group — The official RedManta LLC group on Roblox sometimes posts codes in shouts.
- YouTube — The developers occasionally release codes tied to video uploads or developer updates.
- This page — We pull from all of the above and consolidate everything here. Checking once a day is enough to stay current.
There is no set schedule for new codes, so following the Discord is the most reliable option if you want codes the moment they drop rather than a few hours later.
Beginner Tips
If you just started Summon Heroes, codes help but there are a few habits that will move you forward faster than any single code reward.
Do your daily quests every session. The gem income from dailies adds up significantly over a week. Missing a day means leaving currency on the table that you cannot get back.
Do not summon everything at once. It is tempting to dump all your gems the moment you get them, but saving up for a guaranteed pull threshold — if the game has one — or waiting until a limited hero is in the pool gives you better value per gem.
Sell duplicate heroes you do not need. Lower rarity duplicates especially will pile up fast. Selling them gives you materials to strengthen the heroes you actually use. A leveled three-star is often more useful than an unleveled five-star sitting in your inventory.
Focus on one team before spreading resources. Pick your three to five strongest heroes and build them up before spreading gold and XP across your whole roster. A deep bench is not useful until your main team can clear content consistently.
Check the Nightmare Circus early. It sounds like a late-game mode but some of its easier difficulties are accessible fairly quickly and the rewards are worth the attempt.
For more codes in the same genre, take a look at our All Star Tower Defense Codes page — another game with regular code drops that Summon Heroes players tend to enjoy.
