๐ฎ It is a two-player connection game in which the players first choose a color and then take turns dropping one colored disc from the top into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column, user wins by forming row of four of same color
More than 2 players can play the game at the same time with the same rules.In other words, the number of players is also generalized.For example, there may be 3 players red,blue and green each aiming to achieve 4 in a row on the same board.
There is some issue in the code of game:undo.
Test case: Upon starting the game,play 3 moves and then press Ctrl+Z twice. Firstly only one disc is removed when it should have been 2 and secondly the turn is of the wrong person.
This issue can be further exploited in lots of ways to make theoretically impossible game configurations.
