• That's hard to quantify. It's about 1600 points. The minimum you get per key is 3 points. you can get UP TO 10 keys a day, for a minimum of 210 points for free. That leaves 1390 points to make up on your own.
  
  Each key costs 10 coupons/ingots. So besides the free keys, you would need a bit over 450 extra keys to make up the difference.
  
  The keys sometimes trade in for more, the 3 points a key is just the minimum, which makes it a bit hard to come up with an average. 4500 Ingots should be the absolute MOST you would need. It would definitely be less than that tough.

• Anyone else having trouble to get get keys?
  
  Day 1: Had to use about 700 stamina to get 10 keys.
  Day 2: 200 stamina used so far, not a single key.
  
  Is it just bad rng or something else? If it is rng, can the odds be improved here or maybe make it certain to get keys in every sweep?
  Since we get a limited number of keys anyway, doesn't make any sense to make it hard. This week is the first time I'm having this trouble. Last week, got 5 treasure keys within 10 sweeps every day. Last treasure event like this one, got keys quite easily. This week though, its a complete different stroy. :(
