at level 37 you get spicy pizza, at level 50 you need 157000 to levelup, but that's currently the very last level anyone could get to.

About the slots... A smelter, which originally needs 9500 coins, increase by 9500 at every purchase. 22000, 31500, 41000, 50500. So basically you need 157500 in total to get all the 5 smelters.

A hammermill has 3 three slots at first. 1 for a smelter. The other machines have 2 slots. 9 slots in total. You can do the math.
