Mahjong Connect HD is one of my favorite games. It's in HD, which really enhances the game experience! There is a big board full of square pieces. Each square has a picture on it. I must match two pictures at a time until I clear the board. The faster I clear the board the higher I score. I must clear the whole entire board before the timer runs out or I lose the game and I do not get to go to the next level.
If I ever get stumped, I can click on the help button at the bottom of the page. Then two matching squares will become highlighted. I only get six chances to hit the help button.
