If you uninstall Choctaw Slots and you are playing as a guest your progress may be lost. Updating the game will not cause a loss in player data.
However, the easiest way to ensure you never lose your player history or progress is to connect your account with your Social Account. You may connect with Facebook, Apple, Google or Email when prompted or by clicking on the gear icon on your screen and selecting 'Manage Account'. You'll also be awarded 500,000 FREE coins!
