Game restarts. Frustrating

I get that its an easy game...much easier than 2048, but its therapeutic and enjoyable. The problem is that a game literally takes hours, and its nearly impossible to play right through until it ends. Sometimes you can return to the game, and sometimes the game is not there, and hours of time have been wasted. Until the game saves properly, I dont recommend this app unless you have all day to play!
