Geometry Defense Codes (March 2023)

The new shape of tower defense games.

Get ready to keep your angular world safe in Roblox Geometry Defense! First, choose whether to play alone or with friends, then choose your map. Now strategically place our troops in this epic tower defense game. Can you take all the geometric shapes down before they bounce their way past them and defeat you? Beat hundreds of levels to rise up the leaderboards!  

Geometry Defense codes will usually reward you with a number of free G-Coins, which is the game’s main currency. You can spend G-Coins in the main lobby to purchase Skins (either in Bundles or individually), or Towers. Skins are cosmetic, while Towers open up new troop types for you to deploy in battle. Once you hit level 25, you can also purchase a fifth Tower slot. If you love Roblox tower defense games, check out Action Tower Defense.

Why are my Geometry Defense codes not working?

If you try one of the Geometry Defense Roblox codes above and it doesn’t work, first check for typos. We suggest you cut and paste codes directly from here to avoid missing a capital letter or mistaking a number for a letter. If you’ve tried that, sadly, the code may have expired.

Other ways to get free rewards in Geometry Defense

When you buy certain items or play certain modes in Geometry Defense, you can receive bonus free rewards. For example, if you play in the RNG Insane Mode, you can receive a special lucky mortar skin. And if you buy a Skins Bundle, you get several skins for a discounted price. Finally, you’ll find you get to face special boss waves every five or 10 levels. Each boss has a 10 percent chance to drop a free Charm Piece, so make sure you take them down!

What is Geometry Defense?

Geometry Defense is a standard tower defense-style Roblox game in which you try to defeat increasingly tough geometric shapes as they march past your towers (troops). You can buy and utilize a number of troops, including both melee and ranged, as you complete waves to gain cash and level up. Leveling opens up new options and challenges as you face bigger and stronger bosses and troops.

If you're looking for codes for other games, we have a ton of them in our Roblox Game Codes post! You can also get a bunch of free stuff via our Roblox Promo Codes page. And in the meantime, take a look at the latest news to stay up-to-date on all things entertainment.
