println("Welcome to Minesweeper 6.0! To play this game, here are a few tips.\n\nThe grid you will see is a list of numbers from either 1-64, or 1-256, depending on the size of the grid you choose. Once you have chosen the size, you will have to work your way around the mines to come out alive  ;).\n\nSimply choose a number from 1-64 or 1-256, and the game will tell you if you are safe... or if you have landed on a mine. If you are safe, then you will also know how many mines are near you in the adjacent squares. Good luck surviving...you will need it!\n")
