How to redeem codes

To redeem codes in Monster Battle, open the code input accessible from the main menu or lobby screen, type your code exactly as listed, and confirm. Codes appear to be case-sensitive based on their formatting.

Codes reward Boost Stones (the core weapon upgrade material), Coins (for shop purchases), and Gems (the secondary currency for premium items and egg hatches). The SPOOPY Halloween code is the most valuable active reward, giving 40 Boost Stones plus 300 Gems in a single redemption - enough to meaningfully advance a new player's first weapon upgrades and cover both currency types at once.

Monster Battle entered maintenance mode in August 2024, so new code releases are unlikely without a content update from Capta Games. The four currently active codes are expected to remain valid given the game's status, but checking the Capta Games group is the safest way to confirm if any change occurs.
