Money based profit, progression very slow, you cant battle freely unless you have connection all the time so mega battery and data burner. No option to battle wild pokemon but just have the same ones appear that are basic and stupidly hard to catch on a no pay to play. Reward system is fixed so you have to generally pay to play. The rewards, instance evolve 15 pokemon for a mere 30 basic pokeballs which bare in mind never usually hit when trying curved ball reward though the balls never hit.
