Updated on Mar 12, 2026 5 min read

Puzzles & Survival is a base-building strategy game where you defend your sanctuary from zombies by solving match-three puzzles. Building a strong base and training troops takes a lot of resources—so the developers regularly release redemption codes that give you Diamonds, Green Serum (Antiserum), Speedups, and Combat Manuals for free. Below you'll find the updated list of working Puzzles & Survival codes, how to redeem them in-game, why a code might not work, and where to find more.
