Have you ever played Connect 4 for real? It’s a great game where you need to try and get 4 pieces in a row - that can be horizontal, vertical or even diagonal! It doesn’t matter...as long as they are all your colour!
There are always two teams though, so just make sure that the other person doesn’t beat you to id, otherwise you lose!
This is a great game because you can play with your friends! You can choose to play against the computer, or against a friend. If it’s against the computer you just wait your turn. If it’s with a friend just take it in turns to click on the row where you want your piece to drop!
Good luck, and remember you can "send to a friend" to get all your friends playing too!
