Try this twist on X's and O's gameplay, now with gravity! The rules are similar to Connect Four - you need to get four-in-a-row to win. The four pieces must be next to each other in a single numbered or lettered column.

Click on your disc and drag it to a slot along the bottom left or bottom right of the game grid. Once you have picked the right spot, release your mouse to push the disc onto the grid. If there is not a piece below it, your piece will fall down to the bottom of the grid. If there are discs already in the row or column, your disc will push them further into that row or column. If those discs don't have a piece below them anymore, they will fall too!

Choose to play against a friend or a bot with three different difficulties!
