Delete your Tower Blocks progress
This permanently deletes the anonymous player, its saved game and every device key. It cannot be undone.
Easiest: open Tower Blocks, go to Settings and choose Delete my progress.
Without the app: enter the support code shown in Settings (for example 7K3MQ-9XD2B).
If Tower Blocks is still installed on a phone, that phone keeps its game and backs it up again as a new player, so delete from the app's Settings there instead.
Lost your phone and your code? If you used Google Play Games, install Tower Blocks on another phone to restore your progress, then delete it from Settings. Otherwise your progress is deleted automatically after 12 months without play. You can also remove the Play Games link in your Play Games settings.
