The Tower: Idle Tower Defense runs a creator code programme that lets you support a content creator whenever you spend money on the game. Entering a creator's code sends a slice of your purchase revenue to that creator, and it costs you nothing extra.
Overview
When you buy content in The Tower, you can enter a creator code so that a small share of the proceeds goes to that creator. For in-game purchases, the code is entered in the settings tab. For purchases made through the Webstore, the code is entered on the Webstore itself.
Once entered, a code stays active for 30 days, or until you enter a different code or reapply the same one. The code's owner receives 5% of revenue from in-app purchases and 8% of revenue from Webstore purchases, with no added cost on your end. In some cases you may also see an option to tip the creator directly.
The programme is currently closed access, so new creators cannot apply to join at this time.
