Connect Four is a two player game, in which each player chooses chips of different colours, and takes turns to then drop the chips from the top into a 6 row, 7 column grid. The chips fall straight down, occupying the next available space in the grid. The objective of the game is to arrange 4 chips of the same colour in a line - either horizontally, vertically or diagonally on the grid. Each player gets 21 chips.
Variations of the game
Pop Out 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 chip from the top or — if one has any chips of his or her own color on the bottom row — remove (or "pop out") a chip of one's own color from the bottom. Popping a chip out from the bottom drops every disc above it down one space, changing their alignment with the rest of the board changing the possibilities for a connection. The first player to connect four of their chips horizontally, vertically, or diagonally wins the game.
We fabricated a mechatronic device to play the game against another device/human. The device is capable of thinking on its own using the game algorithm that is implemented in it, and intelligently drop chips into the desired column with the help of mechanical systems.
