# Game Progress

The players must unlock the planets of each galaxy one by one. For example, the first planet of galaxy 2 is only possible if you have already unlocked the previous 1,2,3 planet of the first galaxy. In the same manner, if you want to unlock the third planet of galaxy 4, all other planets of the previous galaxies (1,2,3) must be unlocked. Each galaxy has a special 4th planet that is more valuable in comparison to the other 3 planets. To unlock the special 4th planet of galaxies, the 4th planet of all the previous galaxies must be already unlocked in the same manner as the regular planets.
