These codes can be redeemed by opening Blox Fruits and clicking on the Twitter icon on the left-hand side of the screen. Then, enter the code and click "Try" to redeem it. The rewards will automatically be applied to the game if the code is still active. Its important to note that the effect of the codes doesnt stack, only the duration stacks. For example, if you use two codes at once that both give you 20 minutes of 2x XP, you wont get 20 minutes of 4x XP. Instead, youll get 40 minutes of 2x XP.
