Why are my Ultimate Tower Defence codes not working?

When entering your codes, you may be surprised to see ‘Invalid Code’ pop up as you don’t receive your rewards. In such cases, there are a few reasons for this, and a solution. Codes may expire, meaning they can no longer be claimed for their rewards. There is never a warning when codes expire, so you will only ever know by the code itself not working. Or, you may have misspelled the code, or not input the capital letters properly.

To avoid confusion, copy the code from this article and paste it into the text box where you redeem your code. This way, it will be spelled perfectly. If the code still does not work, then it is because it has recently expired.

Other ways to get free rewards in Ultimate Tower Defense

There are two other ways to get free rewards in Ultimate Tower Defense. On the right, there is a button with a scroll. That button opens the quest menu. The quests will reward you with gems and refresh every day at midnight. By simply playing the game, you get rewards! Also, next to the Tower Shop is a fishing pond. By catching fish, you instantly sell them for free gold! Fish here if you need extra gold quickly.

Alternatively, you can step into the time machine and earn gold AFK. This could be a great way to earn a lot of gold whilst you study or do other things.

What is Ultimate Tower Defense?

Ultimate Tower Defense is a tower defense game. Like all other tower defense games, this one will see you using your towers (heroes and superheroes) to defend the track leading to your enemies’ goal. The enemies (villains and supervillains) will progress along the track, trying to get to the end. You must kill all of the enemies before they reach their goal! Winning rounds will earn you rewards that you can use to buy more towers to take on harder challenges.
