Some levels are impossible to beat without boosters or extra moves. Spend a month using a simulation to find the best moves per screen. it took me 22 days playing about 10 times a day FTP (21 days). On the 22nd day I bought a booster (4.99) and beat the level on the LAST turn, on a "lucky" fall, posted it on reddit. This game is NOT FREE TO PLAY. Don't waste your time on a game that is just a money grab.
