Board game - 4 in a row

Challenge a friend to drop the disc in the classic game line up 4!
Drop red or yellow discs into the grid and be the first to get 4 in a row to win.
If your opponent is too close to 4 in a row, block them with your own disc!
Winners can remove the slider to release all the discs and start the fun again!
Only the four chess games, other accessories shown in the picture are not included!
