Connect 4 belongs to the genre of simple thinking games for 2 people in about 10 minutes, suitable for ages 6 and up.

Similar to the "classic" card game among students, but connect 4 has a higher difficulty and requires you to calculate smartly. The player's goal is to arrange four pieces of his color in a row horizontally, vertically, and diagonally to win. The game has simple, fast rules and many different variations for you to choose from.
Rule:
Place a multi-hole chessboard between two players. Each player chooses a color and takes all the pieces of that color.
The younger player will go first, and then the turn will be alternated between the two.
During your turn, you drop a piece of your color into one of the 7 columns of the vertical chessboard, letting that piece fall freely until it hits the bottom or another piece. Then pass the turn to the next person.
The first player to place four pieces in a row in a horizontal, vertical, or diagonal row wins.
If the board is filled and there is still no winner, the two players are considered tied.
