Can I get suicide skin?

I think it's possible. Each maze is 16 tiles. I need 12 more for this one. I have 9 dice left (No more bonus dice ). 9 * 6 = 54 tiles. 54-12 -16 -16 = 10 so only 3 more mazes I can complete. 450 with about 9 missions and I have exactly 1500. So if I get one 100. I should stop playing this challenge correct.
