There are three difficulty levels for Minesweeper: beginner, intermediate, and expert. Beginner has a total of ten mines and the board size is either 8 8, 9 9, or 10 10.

No, not all Minesweeper games are solvable. In some cases, the initial configuration of mines on the board may be such that there is no safe move to make, leading to an unsolvable game.
