The basic rules of the game work like this: touch a cell to reveal it. If there is a mine underneath, you lose! If not, a number is revealed, which indicates how many of the adjacent cells (up, down, left, right, and diagonal) contain mines. Use the information you have to deduce which cells have mines and which don't. Use flagging mode (touch "Flag" at the top of the screen) to flag cells that have mines. Win by clearing and flagging every cell appropriately. Tip: When a square shows the number n, and you have already flagged n adjacent mines, tap the number to clear all remaining cells! Using this method, you can stay in flagging mode, avoiding switching back and forth, and also reducing the chance of losing due to misclick.

You might have spotted a flaw in this beautiful game though -- sometimes, you have to guess! That defeats the whole point of a deduction game like MineSweeper. Fortunately, most variants of this game will guarantee that your very first guess does not kill you. But it's also easy, especially with larger minefields, to run into games where you are at some point simply forced to guess and no deduction can be made. This can be very frustrating, especially when you reasoned your way through a whole 99-mine game!

But this is where LogicSweeper differs from other versions of this game. LogicSweeper presents you with three different game modes, all of which eliminate the guessing in different ways. Read below to see which style of play suits you! In LogicSweeper Basic mode, game play proceeds just like in classic MineSweeper. However, playing LogicSweeper Basic mode guarantees that any game you play will be solveable without guessing!

When playing in MetaSweeper mode, a random unfiltered game is generated for you, just like in classic MineSweeper. However, you are given a "Hint" button which will (correctly) reveal or flag a random square when you're stuck. But be warned! Hitting the "Hint" button will cause you to lose the game if it is still possible to make a deduction! If you do lose by prematurely requesting a hint, the game will circle one of the cells that you could have flagged or revealed. (And note that you will lose as long as there is ANY cell that can be revealed or flagged that you haven't revealed or flagged. So even if you can tell that you are about to run into a dead-end, don't hit the "Hint" button until you've taken every move you can!)

And by the way, not asking for a hint when you should will also cause you to lose the game, even if you guess right!

Tip: In any game mode, if you lose you can click "LOST" to get an explanation of why you lost; you can also click "WON" for some interesting information too!

Playing in QuantumSweeper mode is much like MetaSweeper -- the game you are given is not guaranteed to be deductively solveable. It differs in terms of how you handle situations where you must guess. In QuantumSweeper, when you are forced to guess, go ahead and do so by playing the odds -- try to reveal the cell that is least likely to contain a mine given the information you know -- or try to flag the cell that is most likely to contain a mine. As long as you make a move which is probabilistically optimal (i.e., at least as likely to succeed as any other move given the information you have) you are guaranteed to succeed! The positions of the mines is therefore not actually fixed when the game begins. Spooky!
