Universal Tower Defense (UTD) is currently running its Winter/Early 2026 events. The most important thing to know about this game’s codes is that many have Level Requirements. If a code says “Invalid” but you know it’s active, you likely haven’t reached the required level (usually 10, 15, or 20) to claim it.
Here is the verified list of active codes for January 2026.

🛡️ Pro Tip: Ice Gifts
Don’t Ignore Ice Gifts: The “Ice Gifts” obtained from codes like
Engage!are used in the event shop. Do not hoard them too long, as event currencies often disappear once the Winter Event fully ends (likely early February).
