Microsoft Minesweeper Online

Play Minesweeper Online. Minesweeper.io is similar to the classic Minesweeper Game with multiplayer. The goal is to clear all of the mines by placing flags on.

Minesweeper is a single-playerpuzzlevideo game. The objective of the game is to clear a rectangular board containing hidden 'mines' or bombs without detonating any of them, with help from clues about the number of neighboring mines in each field. The game originates from the 1960s, and has been written for many computing platforms in use today. It has many variations and offshoots.

Some versions of Minesweeper will set up the board by never placing a mine on the first square revealed.^[1]Minesweeper for versions of Windows protects the first square revealed; from Windows 7 onward, players may elect to replay a board, in which the game is played by revealing squares of the grid by clicking or otherwise indicating each square. If a square containing a mine is revealed, the player loses the game. If no mine is revealed, a digit is instead displayed in the square, indicating how many adjacent squares contain mines; if no mines are adjacent, the square becomes blank, and all adjacent squares will be recursively revealed. The player uses this information to deduce the contents of other squares, and may either safely reveal each square or mark the square as containing a mine.

Gameplay[edit]

Minesweeper has a very basic gameplay style. In its original form, mines are scattered throughout a board. This board is divided into cells, which have three states: uncovered, covered and flagged. A covered cell is blank and clickable, while an uncovered cell is exposed, either containing a number (the mines adjacent to it), or a mine. When a cell is uncovered by a player click, and if it bears a mine, the game ends. A flagged cell is similar to a covered one, in the way that mines are not triggered when a cell is flagged, and it is impossible to lose through the action of flagging a cell. However, flagging a cell implies that a player thinks there is a mine underneath, which causes the game to deduct an available mine from the display.

In order to win the game, players must logically deduce where mines exist through the use of the numbers given by uncovered cells. To win, all non-mine cells must be uncovered and all mine cells must be flagged. At this stage, the timer is stopped.

When a player left-clicks on a cell, the game will uncover it. If there are no mines adjacent to that particular cell, the mine will display a blank tile or a '0', and all adjacent cells will automatically be uncovered. Right-clicking on a cell will flag it, causing a flag to appear on it. Note that flagged cells are still covered, and a player can click on it to uncover it, like a normal covered cell.

History[edit]

Minesweeper has its origins in the earliest mainframe games of the 1960s and 1970s. The earliest ancestor of Minesweeper was Jerimac Ratliff's Cube. The basic gameplay style became a popular segment of the puzzle video game genre during the 1980s, with such titles as Mined-Out (Quicksilva, 1983), Yomp (Virgin Interactive, 1983), and Cube. Cube was succeeded by Relentless Logic (or RLogic for short), by Conway, Hong, and Smith, available for MS-DOS as early as 1985; the player took the role of a private in the United States Marine Corps, delivering an important message to the U.S. Command Center. RLogic had greater similarity to Minesweeper than to Cube in concept, but a number of differences exist:

• In RLogic, the player must navigate through the minefield, from the top left right angled corner to the bottom right angled corner (the Command Center).
• It is not necessary to clear all non-mine squares. Also, there is no mechanism for marking mines or counting the number of mines found.
• The number of steps taken is counted. Although no high score functionality is included, players could attempt to beat their personal best score for a given number of mines.
• Unlike Minesweeper, the size of the minefield is fixed. However, the player may still specify the number of mines.
• Because the player must navigate through the minefield, it is sometimes impossible to win — namely, when the mines block all possible paths.

The gameplay mechanics of Minesweeper are included in a variety of other software titles, including:

• The mini-game Vinesweeper implemented into the MMORPGRuneScape; in this iteration (written by Jagex developer Danny J), the Minesweeper gameplay is given a large multiplayer aspect and the 'game board' adopts a continually resetting timer. This allows for a never-ending game of Minesweeper where the skill is assessed in points rather than 'game completion'.
• The PC game Mole Control (developed by Remode); in this game, the Minesweeper mechanic is integrated into a puzzle adventure game based in a village called Molar Creek, which has been overrun with exploding moles. The player acts as the local inventor's assistant, who is tasked with clearing the village of exploding moles. A time attack mode, called the Molar Creek Annual Mole Control competition, is also available.

Distribution and variants[edit]

Versions of Minesweeper are frequently bundled with operating systems and GUIs, including Minesweeper for OS/2, Minesweeper in Windows, KMines in KDE (Unix-like OSes), GNOME Mines in GNOME and MineHunt in Palm OS. Many clones can be found on the Internet.

Variants of the basic game generally have differently shaped minefields, in either two or three dimensions, and may have more than one mine per cell. For example, X11-based XBomb adds triangular and hexagonal grids, and Professional Minesweeper for Windows includes these and others. There are also variants for more than one player, in which the players compete against each other.

The HP-48Ggraphing calculator includes a variation on the theme called 'Minehunt', where the player has to move safely from one corner of the playfield to the other. The only clues given are how many mines are in the squares surrounding the player's current position.

The Voltorb Flip game in the non-Japanese releases of Pokémon HeartGold and SoulSilver is a variation of Minesweeper and Picross.^[2]

A logic puzzle variant of minesweeper, suitable for playing on paper, starts with some squares already revealed. The player cannot reveal any more squares, but must instead mark the remaining mines correctly. Unlike the usual form of minesweeper, these puzzles usually have a unique solution.^[3] These puzzles appeared under the name 'tentaizu' (天体図), Japanese for a star map, in Southwest Airlines' magazine Spirit in 2008–2009.^{[citation needed]}

In the game Minecraft, the 2015 April Fool's update 'The Love and Hugs Update' added 'Minescreeper'. It is a near exact copy of Minesweeper, except, instead of avoiding the mines, the player must avoid hidden Creepers.^{[citation needed]}

Computational complexity[edit]

In 2000, Richard Kaye published a proof that it is NP-complete to determine whether a given grid of uncovered, correctly flagged, and unknown squares, the labels of the foremost also given, has an arrangement of mines for which it is possible within the rules of the game. The argument is constructive, a method to quickly convert any Boolean circuit into such a grid that is possible if and only if the circuit is satisfiable; membership in NP is established by using the arrangement of mines as a certificate.^[4] If, however, a minesweeper board is already guaranteed to be consistent, solving it is not known to be NP-complete, but it has been proven to be co-NP-complete.^[5]

Kaye also proved that infinite Minesweeper is Turing-complete.^[6]

Rules[edit]

The first click will never be a mine.^[7] It will clear the map and place numbers on the grid. The numbers reflect the number of mines touching a square.^[7]

Minesweeper Rules

Objective and basic concepts

The objective in Minesweeper is to find and mark all the mines hidden under the grey squares, in the shortest time possible. This is done by clicking on the squares to open them. Each square will have one of the following:

Go head to head with other players in a battle for victory. Bloons TD Battles includes unique new tracks, designed specially for multiplayer combat. Watch the action unfold as you and your opponent battle each other's bloons side by side. What will you do? Hunker down for the long game - or go for the quick win with a rush of fast.

1. A mine, and if you click on it you'll lose the game.
2. A number, which tells you how many of its adjacent squares have mines in them.
3. Nothing. In this case you know that none of the adjacent squares have mines, and they will be automatically opened as well.

It is guaranteed that the first square you open won't contain a mine, so you can start by clicking any square. Often you'll hit on an empty square on the first try and then you'll open up a few adjacent squares as well, which makes it easier to continue. Then it's basically just looking at the numbers shown, and figuring out where the mines are.

Gameplay

There are essentially five actions you can take in Minesweeper:

1. Open a square. This is done simply by left clicking on a square.
2. Marking a square as a mine. This is done by right clicking on a square. A little mine icon will show up there.
3. Marking a square with a question mark. This is done by right clicking twice on a square, or right clicking once on a square that's already marked as a mine. Question marks are useful to mark squares you're not absolutely sure are mines, but want to make sure you don't accidentally open them.
4. Clear any marks. Again, right click on the square. Right clicking cycles through the following states: Bomb, Question Mark, Clear.
5. Opening all remaining adjacent squares to a number square. If for example you have a square with the number 1 and you have already marked one mine in one of the adjacent squares you can left click on the 1 square and the remaining adjacent squares will all be opened. This can save a lot of time while trying to quickly clear out squares. If you press on a number where not all adjacent mines have been marked, e.g. the number is 3 and you've only flagged one adjacent square, then the squares will not be opened, to prevent you from accidentally clicking on a number and blowing yourself up! In the old Windows version of this game you used both mouse buttons together to perform this action, but here we just use a normal left-click.

Winning

You've won the game when you've opened all squares that don't contain a mine. If you've opened all the empty/nr squares but haven't flagged the mine squares remaining, they will be auto-flagged and you have won. So, essentially flagging is not required, it's only there to help you keep track of where you think the mines are. The real way to win is open all the non-mine squares. This can be used to gain a tiny bit of speed if you're trying to improve your time :)

Support for tablets and phones

If you’re playing on a tablet, mobile phone or other touch device you won’t be able to right click on the squares. To perform right-click actions you press the square you want to mark and hold until a box pops up showing a flag. If you keep on pressing down, the box will cycle through three states: Flag, Question Mark, Clear. When the box shows the state you want to mark the square with, simply stop pressing down and the square will be marked with that state.

I'm kind of unhappy with how slowly the touches trigger the actions in the game. If someone out there is an expert in JavaScript and 'touchstart' and 'touchend' events, please get in touch :)

Why on earth is Bill watching me?

You might have noticed that Bill is there, but doesn't really give you any hints or do anyting useful. He's just there because I like him, and in the old Windows game there was a smiley face above the puzzle that looked worried while you were clicking, and got sunglasses on when you won. I wanted something similar so I just used Bill for that :)
