It makes slightly more sense when you understand the context: https://www.youtube.com/watch?v=pfa3MHLLSWI

I'm really interested to know what his process was, since he didn't seem to actually know the product he was subtracting 50 from.

Well it seems that he was always going for 4 from the top row, which reliably gives him 25, 50, 75 and 100 (I think). He then uses the ability to divide by 25 to treat these as an additional 2, 3 and 4. So once he has 318, he does (318 * 3) - 2 to get his 952, except via the 25s; ((318 * 75) - 50)/25. It's a hack; increasing the set of available numbers by guaranteeing the presence of a common divisor.

In hindsight, we should have all jumped on this and pretended we understood the rules of Numberwang, in the style of Mornington Crescent. https://en.wikipedia.org/wiki/Mornington_Crescent_%28game%29

I think I should have won by now: https://www.dropbox.com/s/2hokoh94hujyf2j/Screenshot%202014-...

I thought it played normally, and it does for a while, but it always eventually seems to randomly revert your high tiles (I verified that I had at least 1024 by checking the debugger).

[edit:] Ah, I found the code. It's possible to win but you have to survive the small chance that it will perform a random merge and destroy your tile:

        // 0.005% percent chance that we will merge a cell anyway
        if (next && Math.random() > 0.995) {
          next.value = tile.value;
        }

I'd think of the thought process a bit differently than lclarkmichalek, though of course with the same result.

To get close to 952, you can quickly think of 106x9. 106 is easy to obtain and you have a 3. You can get another 3 from 75/25. You're now at 954 with only a 50 left. If you could divide by 25, that would give you the 2 you're missing but you already used the 25, unless you were to divide later. So instead of doing 106x3x(75/25), you do (106x3x75-50)/25.

He could have certainly thought of it another way but based on how players typically play that game, that would be a somewhat logical progression.
