Every extra tile you reveal multiplies your payout because it multiplies your chance of hitting a bomb. Here is the exact survival probability and the multiplier a zero-edge game would pay.

A 25-tile board. Casinos pay slightly less than the fair multiplier; the gap is the house edge.
No. Every configuration carries the same house edge, so the choice only changes how often you win and how much you win when you do.
Both have the same expected value. Early cashouts win small and often; deep runs win rarely and large.
In a provably fair implementation the whole board is fixed by the seed pair before your first click, and you can verify it afterwards.
