Geometry Defense Codes (November 2026) — Free G-Coins for Towers and Skins
7 Geometry Defense codes verified on 12 November 2026 — Roblox Den re-tested DuoGames!' tower defence in-game on 11 November 2026 and TheTechBasket's 9 November 2026 check carries the identical seven codes with identical G-Coin payouts, from twentykay's 120 down to hyperdu's 50; the older ripspace group is held off as split between the trackers. Includes the verified Duo Games Discord server.
There are 7 working codes listed for this game right now: twentykay, 15thousand, 10klikesssss, cube, hyperdu, gdf, epic1mvisits. Every code below shows its reward, and the list was checked on 2026-11-12.
Geometry Defense is DuoGames!' tower defence with a geometric twist: waves of hostile shapes march on your base, and you answer with towers bought from the shop, voting on the map before each run and trying to hold out as the waves harden. G-Coins are the money that matters here, paying for new towers and skins in the lobby, and codes are the fastest way to stockpile them without grinding matches. Two separate checks landed within days of each other and agree completely: Roblox Den re-tested the game in-game on 11 November 2026, and TheTechBasket's own tracking, last checked on 9 November 2026, carries the identical seven strings with the identical payouts. Older lists from April 2024 and April 2025 back most of the seven as well. What the fresh checks would not confirm has been left off, however familiar it looks from those older pages — names such as ripspace, 3mvisits and gtd sit in limbo between the trackers, with one filing them finished in late October and Den's test leaving them unverified, so none of them is presented as working or as retired below.

Expired codes
The retirements both trackers settle on are Charm, eventsoon, 5kvisitsyay, discord2, likeandfavourite, grind, geometrymas, tenkay, befbday, 1500likes, 1250nice, hundred and 750likes — Roblox Den files every one of them expired, and TheTechBasket's archive carries the same thirteen names. One reward is worth a footnote: the two oldest lists, from June 2023 and April 2024, describe epic1mvisits as handing over a Shapegunner skin, yet every later record — Pro Game Guides in April 2024, Pocket Codes in April 2025 and both November 2026 checks — puts it at 100 G-Coins, which is the figure printed above. Gamer Journalist's April 2024 page also filed gdf among its expired codes, but Pro Game Guides listed it as working that same month and both fresh checks have it live, so the newer evidence is followed here.

Frequently Asked Questions
How do you redeem codes in Geometry Defense?
Open the Settings menu using the button at the bottom of the screen, type your code into the Enter a Code box exactly as it is printed, and press Redeem. The G-Coins land in your balance immediately.
What do Geometry Defense codes give you?
G-Coins, the currency spent on towers and skins in the lobby. The seven working codes pay out between 50 and 120 G-Coins each: twentykay pays 120, 10klikesssss pays 110, and 15thousand, cube and epic1mvisits pay 100 apiece.
Why are codes like ripspace and gtd missing from the working list?
Older lists from 2023 to 2025 carried them as working, but the two November 2026 checks could not confirm them: Roblox Den's in-game test of 11 November 2026 left them unverified, while TheTechBasket filed several of them expired on 26 October 2026. With the trackers split, they are shown neither as working nor as expired.
Where do new Geometry Defense codes appear?
DuoGames! announces codes around updates and milestones through its Roblox group and its Discord server. Group members also earn ten per cent more from matches, so the group is worth joining even between code drops.
