Yes, our game is set up so that all its levels can be completed without making purchases. To complete the harder levels, you will need more time, the right strategy, increased effort, more attempts, and, consequently, more extra lives, which you can get as a gift from friends.
We recommend joining the game's Facebook page. This group will allow you to find other players who you can add as friends. With their help, you can get extra lives, so you will not have to wait for your hearts to be restored based on the standard timer.
In addition, you can earn lives, rubies, and boosters in a variety of game activities and by assembling puzzles. This will also allow you to complete hard levels faster.
