Wow, can't believe I neglected to submit so many rounds and bonuses. So this is why my credits randomly jumped. =P

Oh. Also... the answer to mental 9:

Sum of 3 outer numbers divided by the sum of the digits in the sum.

5+6+7 = 18. 1+8 = 9. 18/9 = 2. Which is why 3 of the ones are divisible by 9. But, the upper left doesn't work dividing by 9.... so... the upper left total is 42. 4+2 = 6. 42/6 = 7. 7 is the answer.

Rubix is the only person who solved that.... I also posted it on another forum about 2 days after devonin posted it here, and not one person has solved it there either.

Ugh. So tricky. ....

It wasn't too bad if you used "reasonable Occam's-Razor statistical logic". By this I mean "most likely Dev is not going to be super evil and create a bunch of red herrings -- if I find a cool pattern, it's likely relevant to the final answer in some form". The only "red herring" in this case was the fact that the first three sum to numbers ending in 0, but this was mainly because I misunderstood the problem at first. Once I noticed that the inner numbers were the ANSWERS, that means the resulting numbers were numbers ending in 0 minus the answer, which is peculiar and led me to this reasoning:

e.g. "There's no way that the fact that the first three are divisible by 9 is a coincidence. Therefore there must be some rule that actually applies to all four of these boxes and just-so-happens to produce a /9 for the first three, but something else for the fourth one. Since the /9 must come from these numbers, I should figure out how to work the numbers in the first three boxes to somehow yield a /9, and then see if this rule works on the fourth box"

After thinking of it in this manner I got the answer pretty quickly

i did think of that logic.... but i didn't pursue it very far, or think about it very long. oh well.

I think I donated 200k credits to this tourney. Was it ever used as a prize? If so, kool. If not, I'd like to ask for the credits back.

Prize Pot 260,000 (I know it should have been more, but I put in 100k, and credit bug recalculations dumped me down to like...much less than that, so this is basically Ledwix's 240, Jerry's 10 and 10 more of my own)

1  Tass tends to forgo credits
2  60,000
3  50,000
4  40,000
5  30,000
6  20,000
7  17,000
8  15,000
9  15,000
10 13,000

Short answer... yes, your credits were used to pay out the 2nd-10th place finishers.
