I’ve been playing Mahjong Rivers for a long time. This game is really tough. The weird thing about it is it lies in the bedrock of rocky scoring. The timed game requires not only quickness, but also accuracy! Make a mistake and you gain 5 seconds. You can’t do that too many times. I thought the time of about a minute and a half was really good, however I only got 2 out of 3 stars. And, I didn’t make a mistake! Whew!! Most other games just do timing. I’ll keep my oars in the water and see where this goes. I hope I don’t run into any rapids...It is a challenging game. I’ll give it 4 stars for now. You gotta try this game!
