But what about the slot that have 1500 coconuts? I play them at hard.

Could it be that the program is stuck on that number no matter the difficulty?

Also, does the program "learn" a gamers playing style? I am asking because the villagers are coming out in "uniforms".
Outfits that I use when the puzzle is complete are the ones repeated in the next game and two or three villagers will be in it and/or their children will also have them.

Not all the villagers are in uniform and no it doesn't always happen.
