It's nice, but easy too. Once you decide the last number you have to move accordingly

That's the thing with problem creation, it becomes either too easy or too difficult. (Not saying that this one is way too easy)

I recollect someone suggesting letting bots(AI) play a number of variations of the game first and then use the outcome to ascertain the difficulty - may be an overkill for a fun game like this?

after level 50 there are black & white tiles that increase/decrese the value when you step on them.

Not so easy anymore

it's even easier to guess the number to figure out because it must be between min Black an MAX White
