The Battle Spinner is a feature added to BTD Battles in the 3.10 update. This spinner has prizes including medallions, a free ticket to a club battle, free entry into the highest tier arena and a free banana farmer (worth File:Medallion Icon.png100). Once spun, you must wait 8 hours before spinning again. There is currently no way to skip the waiting period with an in-app purchase. However, watching an ad will hurry the timer by an hour.
