Neggsweeper is one of the few (if the only) Neopets game with a cumulative score. You pay 30 NPs to start the game so have at least that amount on hand.
If youve played Minesweeper, than this game is identical. Clicking on a negg will reveal a number, an empty space or a red negg (Game Over, hombre). By the power of deductive reasoning, you should be able to find all the empty spaces and therefore avoid all the mines.
I assume that there are many starting points for Neggsweeper, but Ill start with the two main ones I can think of.
