I was testing daily rewards and got to conclusion. When you grind the same door for daily reward at first 6-8 days it rewards you with random consumable powers, but after that you always receive free caches. I've done the testing three times during a half of a year period and the result is always the same.
That's probably either a bug or a scripted moment, don't know. So if you really need caches, just grind the same door always every day, after a week or so you will loot caches with every daily visit. If you do want other rewards, then don't grind same door, always choose different ones!

Nice, but now that Fizzer's secret is out, the new hyped 'update' will just be fixing this.

I've only ever selected the middle door and I always get random stuff, not sure what you mean.

I haven't been watching closely, but I always pick the left one (I think), and I get different rewards. It could have to do with the randomization seed based on your machine's clock? Obviously I'm much big IT programmer hacker.

It might be possible that the available options are skip level, supercharge army camp, free cache (or whatever) and you’re at 5/5 on the other two. I do think it’s pretty funny that you’re treating your n=1 screenshot is some rigorous proof point though.

I have been choosing the right door each day for weeks. I seem to get a variety (maybe more caches than others?). I have also had several where I had to use them immediately (rather than claim and save for later) because I already had 5 of the same.

Hmmmm, okay, it was 6 caches in a row (when I had them 5/5 from the start) before getting another reward. Maybe I was wrong, but this series of lots of caches in a row has happened to me every time I began to open only same door each day, not shuffling them...
got time warp today

I had a string of about 5 fog busters in a row, choosing different doors each time

Interesting observation. Do you have more data? It'll be nice to have some data to analyze, something like "I got x caches out of 40 days choosing the same door every time, while getting y caches out of 40 days choosing different doors every time". Then we can do some statistics to see if there's indeed a statistically significant difference.

"6 caches in a row" doesn't mean much because random rare events are not actually rare if the action is performed for many times. For example if you throw a dice for 10000 times, it's extremely likely that you'll get 10 odd numbers in a row at some point.

Gotcha, can do that! =D

Same door (right) today. After many free caches in a row (have not been counting), today I received a Time Warp.
