Four Square II

Four Square II takes the idea behind tic-tac-toe and gives it a fresh twist. Instead of a line of three, you are trying to form a square of four gems in your color, while your opponent races to do the same.

How to Play

Click an empty space to place one of your gems. Each completed four-block square earns you points. Your opponent is placing gems too, so you need to balance building your own squares with blocking theirs. Thinking a few moves ahead, much like in chess, is the key to winning.

Tips

• Watch for spots where your opponent needs just one more gem, and take them first.
• Place gems that could complete more than one square at once.
• Avoid spreading out too much early on.
