lvl 49 is impossible.

[LaFleur221]

more then a year later afther tere was a discussie on this. This still is a problem! ferry sad u cant play out the game beacuse u start lvl 49 without any resourses and u need 8 iron to break the ice block but u only geth 5. U cant blow up the ice block so u never can finish this lvl. ferry sad the developers dosn't do anything about this.

Very old, but since noone's answered and it's still the newest topic...

It's totally beatable, but doing it in a reasonable time is another story. You have to use the bomb timed powerup until it picks that ice block / wall to blow up. Unfortunately, there's no telling how long that will take, and then you have to get a minimum of 6 diamonds from the random resource mine. It's probably best to wait until you have 6 diamonds before spending any to knock out the "stock 6 diamonds" goal. Now how you get 3 stars with all of this waiting to get lucky on random picks, I have no idea.
