Connect 4 Multiplayer

Connect 4 Multiplayer Description

Connect 4 multiplayer is a two player board game similar to Tic-Tac-Toe. Each player takes turns dropping a colored disc into a board that has 7 vertical columns and 6 horizontal rows. The goal of the game is to connect four pieces of the same color–vertically, horizontally, or diagonally–before the other player does so.

Connect 4 game ends in a tie if neither player connects four when all the 42 board positions are filled up. The first player begins by dropping his/her yellow disc into the center column of the game board. The two players then alternate turns dropping one of their discs at a time into an unfilled column, until the second player, with red discs, achieves four discs in a row, diagonally, and wins.

The two players then alternate turns dropping one of their discs at a time into an unfilled column, until the second player, with red discs, achieves a diagonal four in a row, and wins the game. For games where the board fills up before either player achieves four in a row, then the games are a draw.

connect 4 multiplayer is a two-player game with perfect information for both sides. This term describes games where one player at a time plays, players have all the information about moves that have taken place and all moves that can take place, for a given game state. Connect Four also belongs to the classification of an adversarial, zero-sum game, since a player’s advantage is an opponent’s disadvantage.

One measure of complexity of the Connect 4 Multiplayer game is the number of possible games board positions. For classic Connect 4 Multiplayer played on 6 high, 7 wide grid, there are 4,531,985,219,092 positions for all game boards populated with 0 to 42 pieces.

The game was first solved by James Dow Allen (October 1, 1988), and independently by Victor Allis (October 16, 1988). Allis describes a knowledge-based approach, with nine strategies, as a solution for Connect 4. Allen also describes winning strategies in his analysis of the game. At the time of the initial solutions for Connect 4, brute-force analysis was not deemed feasible given the game’s complexity and the computer technology available at the time.

Connect 4 Multiplayer has since been solved with brute-force methods, beginning with John Tromp’s work in compiling an 8-ply database (February 4, 1995). The artificial intelligence algorithms able to strongly solve Connect Four are minimax or negamax, with optimizations that include alpha-beta pruning, move ordering, and transposition tables. The code for solving Connect 4 with these methods is also the basis for the Fhourstones integer performance benchmark.

The solved conclusion for Connect 4 Multiplayer is first player win. With perfect play, the first player can force a win, on or before the 41st move (ply) by starting in the middle column. The game is a theoretical draw when the first player starts in the columns adjacent to the center. For the edges of the game board, column 1 and 2 on left (or column 7 and 6 on right), the exact move-value score for first player start is loss on the 40th move, and loss on the 42nd move, respectively. In other words, by starting with the four outer columns, the first player allows the second player to force a win.

Rule variations

There are many variations of Connect 4 Multiplayer with differing game board sizes, game pieces, and/or gameplay rules. Many variations are popular with game theory and artificial intelligence research, rather than with physical game boards and gameplay by persons.

The most commonly used Connect 4 Multiplayer board size is 7 columns × 6 rows. Size variations include 5×4, 6×5, 8×7, 9×7, 10×7, 8×8, Infinite Connect-Four, and Cylinder-Infinite Connect-Four.

Several versions of Hasbro‘s Connect Four physical gameboard make it easy to remove game pieces from the bottom one at a time. Along with traditional gameplay, this feature allows for variations of the game. Some earlier game versions also included specially marked discs, and cardboard column extenders, for additional variations to the game.

PopOut

“PopOut” redirects here. For other uses, see Pop Out (disambiguation).

PopOut starts the same as traditional gameplay, with an empty board and players alternating turns placing their own colored discs into the board. During each turn, a player can either add another disc from the top or, if one has any discs of his or her own color on the bottom row, remove (or “pop out”) a disc of one’s own color from the bottom. Popping a disc out from the bottom drops every disc above it down one space, changing their relationship with the rest of the board and changing the possibilities for a connection. The first player to connect four of their discs horizontally, vertically, or diagonally wins the game.

Pop 10

Before play begins, Pop 10 is set up differently from the traditional game. Taking turns, each player places one of their own color discs into the slots filling up only the bottom row, then moving on to the next row until it is filled, and so forth until all rows have been filled.

Gameplay works by players taking turns removing a disc of one’s own color through the bottom of the board. If the disc that was removed was part of a four-disc connection at the time of its removal, the player sets it aside out of play and immediately takes another turn. If it was not part of a “connect four”, then it must be placed back on the board through a slot at the top into any open space in an alternate column (whenever possible) and the turn ends, switching to the other player. The first player to set aside ten discs of his or her color wins the game.

5-in-a-Row

The 5-in-a-Row variation for Connect 4 Multiplayer is a game played on a 6 high, 9 wide, grid. Hasbro adds two additional board columns, already filled with player pieces in an alternating pattern, to the left and right sides of their standard 6 by 7 game board. The game plays similarly to the original Connect Four, except players must now get five pieces in a row to win. Notice this is still a 42-ply game since the two new columns added to the game represent twelve game pieces already played, before the start of a game.

Power Up

In this variation of Connect Four, players begin a game with one or more specially marked, “Power Checkers” game pieces, which each player may choose to play once per game. When playing a piece marked with an anvil icon, for example, the player may immediately pop out all pieces below it, leaving the anvil piece at the bottom row of the game board. Other marked game pieces include one with a wall icon, allowing a player to play a second consecutive non winning turn with an unmarked piece; a “×2” icon, allowing for an unrestricted second turn with an unmarked piece; and a bomb icon, allowing a player to immediately pop out an opponent’s piece.

Connect 4 Multiplayer Tips & Tricks

Connect 4 Multiplayer Winning Strategies

How can the above tips and tricks really improve your game? The reality is that Connect 4 is not much a game of luck and chance. It is based on strategic moves and well thought out reactions by opponents. It really comes down to how you think and how you can plan ahead.

By learning a few extra tips and tricks to winning Connect 4 Multiplayer, you can effectively increase your chances of winning. For me, that is well worth the time and effort involved. Below are 10 of the tips, tricks, and strategies that I have learned along the way…and that are currently helping me be the best Connect 4 Multiplayer player I have ever been.

1. Always anticipate your opponent’s next move.

There is a great deal of strategy involved in Connect 4 Multiplayer – that is an undeniable fact. Being strategic involves being able to think ahead and almost guess what your opponent will do next.

For first time players, I have noticed that the rack can be quite challenging. So, what’s one effective advice for first-time players? Well, it’s about giving the next move a lot of forethought. Before you take your turn, make sure that you consider what your opponent’s response to that move will be. This prediction can help you to decide if the move is actually a good one or not. Anticipating the next move in this way could help you win the game.

2. Plan multiple moves ahead of time.

Planning more than one move ahead is the best way to ensure that a win is more likely. You will find that every move in Connect 4 Multiplayer creates a reaction move from the opponent. You can use this to your advantage. Before you actually make a move, consider what the knock-on effect will be. Perhaps a move you make now will earn you a four in a row in 2 moves time, based on your predictions. Always think ahead – you only stand to gain.

Of course, you are not only looking for what your current move might open up for you in a few moves time. You are also looking at how any of your moves might possibly be positive for your opponent. You do not want to play a move that inadvertently spurs your opponent onto a win.

3. Play the middle column.

Getting control of the center column is vitally important if you want to win in Connect 4 Multiplayer. In fact, Connect 4 is a solved game, and playing the middle column is part of guaranteeing a win. I have personally found that when I gain control of the center column early on, my chances of winning are greatly increased. Why does having control of the center column increase your chances of winning? Well, the rules make it so.

On a standard rack that has seven columns, any four connected pieces that are not vertical must include one game disc from the center column. If you control the center column, it is going to be hard for your opponent to connect any four of a kind that is not vertical.

4. Block your opponent.

One of the best ways to ensure that you do not lose is to focus on ensuring that your opponent cannot win. Blocking your opponent is the best way to do that. You can defend against the opponent’s advances by placing your game discs into any slots that would allow them to complete a four in a row connect. While this will ensure that your opponent cannot win, it will also mean that you do not form any Connect 4s of your own.

5. Keep your eye open for game-ending spaces.

In my experience, there are times that the rack has a space on the board that would serve up a great Connect 4 to me or my opponent. It just depends on who plays there first. The game will be over as soon as that space is filled. A good strategy is to ignore all the spaces that are above the game-ending space in the very same column.

6. Avoid playing directly below a game-ending space.

If you play below a game-ending space, you might give your opponent the perfect opportunity to create a Connect 4 and win. Here is where you can be a little sneaky to ensure yourself a win. You can set up a Connect 4 in such a way that your opponent is forced to block your connect in the critical space. So, for most of the time, try to not play directly below a game-ending space. Rather force your opponent to do so.

7. Fork threats.

I have watched this one in action before and been astounded at how many times I have been caught out by it. Much like Tic-Tac-Toe, a forked threat provides you with a double opportunity to win and puts your opponent in an almost impossible position (actually, it is an impossible position for sure).

How do you fork a threat? Create two possible connects in two spaces – usually one on top of the other. This leads to a win because your opponent can block only one of your connects, leaving the second connect open for you to claim a victory.

8. Use the opponent’s mistakes to your advantage.

A mistake is when a player does not block a player’s move and it ensures that they win. To prevent this from happening, you have to pay close attention to what is happening on the rack. If your opponent fails to block you, you have a winning opportunity that you can take advantage of. Do not get distracted during your game. Be fully engage. Your opponent’s distractions might put him at a disadvantage.

9. Play on the offensive.

Do not get caught up with only playing defensively. I have found myself focusing so hard on blocking my opponent that I forget to play offensively. This means that I miss out on making connections with my own discs. I am sure other players have found themselves doing the very same thing.

Okay, so playing offensively is a good thing, but how do you do it? You can build outward rows horizontally. You can stack discs one on top of the other in order to form connections that are vertical. You can make diagonal connections using your rows and columns. Of course, be strategic about it.

10. Practice, practice, practice. 

If you only ever play Connect 4 on the days you want to win the game, chances are that you are not going to improve your game strategy very quickly. Try setting up the game rack in your spare time and practice, even if you have to play against yourself. It will help you to predict certain moves and experience first-hand what to do. Of course, if you have a partner or a friend around, encourage them to play with you casually.

The more you play the game, the more practice you will get and the better your chances of winning are the next time you play competitively.
