BHS, I don't see that the problem was correctly presented if the answer is as you explained it. In your initial post you say the following:

Identical in appearance, they're identical in the function.
Yet in the "solution" you say this:
Quote from BlueHorseshoe:
Ding Ding Ding Ding. We have a winner. Whatâs different about that machine is people have used modern electronics to give a higher ratio of near misses.
It seems to me that if the "modern electronics" are set to show more apparent "near misses" than the other machines, then the machines cannot be "identical in function".
So what am I missing? How can you manipulate in ANY way the (so called) "behavior" of one machine and yet call it "identical in function"??
As an added "gripe" with the solution (probably irrelevant)...a real life problem with this solution is that the electronics have nothing to do with payouts, near misses or anything at all. Modern slot machines are run completely by computerized random number generators. The only REAL difference between the old mechanical slots and today's electronic slots is that on the old slots, the wheels would spin until friction slowed them down to a stop. In modern machines, the number generator determines IN ADVANCE WHILE THE WHEEL IS STILL SPINNING WHERE IT
WILL stop. This is far more random than a mechanical slot....since mechanical slots may have unbalanced wheels, uneven ratchets, (some filed ratchets on "crooked" machines were very common years ago) or any of a number of other mechanical imbalances.
My understanding of this comes from many conversations with slot techs as they serviced the machines. So unless they all lied to me, this is how they work. There is no way to program a wheel to stop on any particular notch. Not that it is not possible. It is just not how the machines are designed. What makes the big winners so rare is the enormous (in "spots") size of the wheels.
Consider a machine with 4 wheels each with 40 possible stops. This gives 2.56 million possible combinations. Now combinations can certainly be made to be common, or at the other extreme, it is possible to make the odds of hitting a particular combo one in 2.56 million. Or anything in between. BUT....the second you change the way the symbols are arranged on the wheels, it seems that the "identical in function" part goes out the window.
Apart from this layout of symbols on the machines wheels, the probability of any wheel stopping on any symbol is exactly as random as the toss of a pair of dice (or 4 or 5 dice may be a more appropriate analogy....whatever...it doesn't matter really), or the spin of a roulette wheel. I know this is contrary to the beliefs of many. But it is how electronic machines work. No "memory"...just random. And that is enough to make the payout "adjustable" enough by laying out the symbols.
Again, the only control being the way the symbols are stuck on the wheels seems to exclude the machines from being "identical in function".
I guess as a hypothetical exercise, the answer could suffice. As a real exercise, I do not see the answer being legitimate.
I spent too much time in Vegas I guess.
Peace BHS....and next time in Chaing Mai we WILL make it to House in Park...sorry I got sidetracked last month. Will keep you posted.
