The steps below should help you unlock your game again, as long as you're using the same Google Play Account that was used at the time when you purchased the game.
- Make sure you have a stable internet connection and tap the "restore purchase" button in the game, located in the game main menu. The game should then unlock and you’ll be able to play all the levels without ads.
- If you just made the purchase in the past 1-2 hours, make sure the transaction has been completed. You can check your purchase history to see if the purchase has been completed. If not, then try to purchase the game again. Open your purchase history here: https://play.google.com/store/account
- Make sure you have purchased the item using the Google Play account you are logged in with. To see if this is the case, check you purchase history to see if the purchase is listed. If not, then make sure you are logged in with the correct Google Play account. Open your purchase history here: https://play.google.com/store/account
Please note: you can always go through the purchasing process again, as long as you're using the same Google Play Account (email address) that you used when you purchased the game. You will not be charged twice, but should receive a message that you already own the game and the levels should unlock immediately.
