How to redeem codes

Nightmare Defense codes are redeemed through the in-game code input - look for the codes interface in the main menu, enter your code, and confirm to claim the reward. Codes appear to be case-insensitive based on the mix of uppercase and lowercase formats seen in released codes, but entering them accurately still avoids errors.

Codes reward Gems, Dice, and Souls - the three core progression materials. Gems are used to summon new Nightmare units, while Dice and Souls fuel the evolve system that upgrades units to stronger forms. Milestone codes like RELEASE have given 500 Gems plus 2 Dice and 2 Souls at once, making them the most valuable to redeem quickly. Smaller codes like ALPHATESTER1 and PLAYNMCLASH give 100-150 Gems for lighter boosts.

ApparentlyGames ships weekly updates every Thursday, which is one of the most consistent update cadences in the genre. New codes tend to arrive alongside major content drops. The best approach for catching new codes is following the ApparentlyGames group page and checking the game description after each Thursday update.
