Could you give me some tips on operation gumball?

That tutorial is really helpful. But you don't have to be good to win a trophy; I got mine on level 2 two days ago. You do have to play a the normal, not the easy mode for the trophy. I think I read somewhere that there are 30 levels, but I wouldn't know from personal experience, since I'm really not good at this game.

Try these common combinations: 123,456,789,012,345,678,901,122,222,233,244,255,266,277,288,299,201. For the combinations that include 4 numbers try these combinations: 1234,5678,9012,3456,7890,9001,4725,9017,7846. Hope I could help!
