How to redeem codes

To redeem codes in SCP Tower Defense, look at the left side of the screen - the code input is located adjacent to the daily reward button. Click the code input area, type your code, and submit. Codes are case-sensitive, and some codes include spaces - for example, event-named codes like "goc event" require the space to be included exactly as written.

SCP Tower Defense codes reward Coins (the primary progression currency), Shards (secondary currency for tower upgrades), and Tokens (a rarer tertiary currency for premium unlocks). The Christmas 2024 code rewarded 1,500 Coins, 75 Tokens, and 150 Shards. Milestone codes tied to visit counts typically give larger amounts than event codes. Tokens are the most valuable reward since they unlock premium content otherwise requiring Robux.

New codes are announced through developer Mashiusam's Twitter/X account and the SCP Tower Defense Discord server. The active Fandom wiki at scp-tower-defense.fandom.com also tracks current and expired codes reliably. Codes often expire within days of being posted, so checking these sources as soon as major updates drop is the best approach.
