I really enjoyed playing Super Mahjong 3D on bubbleshooter.net. After a brief but useful tutorial, which takes about 30 seconds to get through, the gameplay starts off with a mahjong board that is made of bubble cubes instead of tiles, and the matching is super simple to start with. That is where the challenge came in for me though because it doesn't stay simple for long. Easy matches give way to more complicated patterns, and the pace keeps on increasing while the timer does not. You will have a great time playing this fun and frantic matching game on bubbleshooter.net.
