About Geometry Defense

What the game is about and where to play it

Geometry Defense (GDF) is a geometric-aesthetic tower defense game developed by DuoGames! where players defend against 25 waves of escalating shape enemies using purchased and placed towers. Created in August 2022, it has reached over 20.9 million visits and 26,500 favorites with a 93.0% approval rating from 26,000 votes. The current development team is led by CoffeeDummy (animations, balance, maps) and epeedacier (scripting, co-owner).

The Charms system - introduced in January 2026 - is the standout addition that elevated GDF beyond the standard tower defense formula. Players equip up to 3 charms simultaneously for stackable tower buffs, with 20 total charms across four rarity tiers:

🏆 Survive 25 waves of geometric shape enemies, scaling in HP and speed each round
💎 Farm Golden Charms (0.01% drop rate, 10x rarer than Normal) for maximum tower optimization
⚔️ Kill boss waves every 5-10 rounds for a 10% chance to earn a Charm Piece crafting material
🗺️ Vote on community maps each match and coordinate with up to 32 teammates for synergistic tower placement

G-Coins are the primary currency earned from match completions, spent on towers in the Shop, skins in the Skins Shop, and charms. DuoGames! group members earn +10% G-Coins from every match. Boss wave badges (defeating Veyr,TheWicked and others) unlock auras as permanent cosmetic rewards.

The developer lists milestone thresholds directly in the Roblox game description, making it easy to track when the next reward drop will arrive. A Fandom wiki at roblox-geometry-defense.fandom.com documents towers, charms, and wave strategies in detail.

What is Geometry Defense?

Geometry Defense (GDF) is a tower defense game on Roblox developed by DuoGames! with a geometric art style. Players equip towers purchased with G-Coins, vote on a map, then defend against 25 waves of escalating shape enemies. The Charms system adds deep equipment management with 20 charms across four rarity tiers.

Who made Geometry Defense?

Geometry Defense was created by DuoGames!, a Roblox developer group. The current team is led by CoffeeDummy and epeedacier. The game launched in August 2022 and has been actively updated through April 2026.

How does the Charms system work in Geometry Defense?

Players can equip up to 3 charms simultaneously, each providing buffs or debuffs to all towers. There are 20 total charms across four rarity tiers: Normal (0.1% drop from enemy shapes), Golden (0.01% - ten times rarer), Boss-based (from boss waves), and Special (from events or event shops). Boss waves have a 10% chance to drop a Charm Piece, used to craft charms.

What are G-Coins used for in Geometry Defense?

G-Coins are the primary currency earned from surviving match waves and from codes. They are spent in the Shop to buy towers, in the Skins Shop for cosmetic tower variants, and in the Charms Shop. Joining the DuoGames! group gives a permanent +10% G-Coin bonus from all matches.

How do boss waves work in Geometry Defense?

Boss waves occur approximately every 5-10 waves and feature high-HP enemies significantly tougher than regular waves. Killing a boss has a 10% chance to drop a Charm Piece. Beating certain bosses also unlocks permanent aura cosmetics - defeating Veyr,TheWicked awards a badge and aura, and there are additional boss badges for the second and third bosses.

How do I get Golden Charms in Geometry Defense?

Golden Charms drop from the same enemy shapes as Normal Charms but at a 0.01% rate - ten times rarer. Focus on the specific enemy type that drops your target charm and play consistently across many matches to accumulate drops. Boss wave farming for Charm Pieces is the more reliable endgame activity.
