CONNECT FOUR VS TANTRIX

Connect Four (also known as Four Up, Plot Four, Find Four, Captain's Mistress, Four in a Row, Drop Four, and Gravitrips in the Soviet Union) is a two-player connection board game, in which the players choose a color and then take turns dropping colored discs into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs. Connect Four is a solved game. The first player can always win by playing the right moves. The game was first sold under the Connect Four trademark by Milton Bradley in February 1974. Connect Four 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 Four game is the number of possible games board positions. For classic Connect Four 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).

Tantrix is a hexagonal tile-based abstract game invented by Mike McManaway from New Zealand. Each of the 56 different tiles in the set contains three lines, going from one edge of the tile to another. No two lines on a tile have the same colour. There are four colours in the set: red, yellow, blue, and green. No two tiles are identical, and each is individually numbered from 1 through 56. In the multiplayer version of the game, each player chooses a colour, so there are between two and four players. Each draws one tile from the bag, and the person who draws the highest number goes first. Each player then takes five more tiles from the bag, and places all six tiles face up in front of them. The first person plays one tile, usually with their colour on it. Play then rotates clockwise. After playing a tile, each player takes a replacement tile from the bag, so that they always have six in front of them. Tiles played must match the colour of the edges adjoining it. When three tiles surround an empty space so that it is effectively half covered this is called a forced space. If the person whose turn it is has a tile that fills that space they must play it. The player repeats this process until there are no more forced spaces that they can fill, at which stage they make a free move, where they can play any tile as long as they don't breach the three restriction rules given below. Once they have had a free move, they must then fill any more forced spaces that they can. Thus one player's turn can consist of several moves.
