Math Mahjong

I have just found a new, highly addictive math game. It's Mahjong.... but with math terms. The goal is to click the tiles to make a mathematically true equation  (but remember your order of iperstions!!). Only the tiles on the ends of each row are lit up and avaliable. So if you run out of equal signs and need to get to one, you need to incorporate all the tiles on the edge of the tile's row before it is avaliable. Once you get the hang of it, it can be fun to make challenging combinations using multiple signs. It reminds me of the Number Challenge activity I have in my classroom. Check it out below (I think the link only works on Google Chrome).

If I remember correctly, my high score was about 72,000. Can you beat my score??
