Hello @serz Hearty Welcome to the Candy Soda section of our friendly King Community
I am sorry to say that the Community supports English language ONLY for everybody to communicate and understand better. Hence, post your comment again in English, if it is pertaining to "Loosing the level progress in your game"!
1) If you have already saved your game before through Facebook or Kingdom account, follow the suggestions in "Problems with retrieving Saved game";
2) If you have not saved your game till now, follow the steps in the section part "Didn't save the game, is it too late"! With this step, the "Player Support Team" will be able to retrieve your game progress. Please note that they can restore all those levels with only 2 stars, but cannot give highest scores that you have achieved in the levels!
Hope this made sense and clarifies! Please post back and let us know how it went and also if you need further assistance.
Hope everything works out fine! Have a great weekend ahead!
