Ratings and reviews

Opinion after 1 game. PHENOMENAL. The tiles are very easy to see, you've enabled zooming popups when needed. Suggested hands help newbies and give me a quick reminder if I don't have my card on me. The animations are super cute (bird bam!). One future silly request: l'd like to rename the bot players so I can use my friend's names and screenshot when I win. LOL. But once multiplayer works it'll be my real friends anyway. Dragging tiles was tricky but worked (easier left than right.) NICE JOB!

As a complete novice, I really appreciated the New Player tutorial that is available. The game jargon is intimidating at first, but after reading through the rules and seeing the patterns shown clearly, I have a lot more confidence in trying the game out. Got my butt handed to me on my first game, but I had fun! Highly recommend!!

I play mah jongg in person and never had any desire to play online but I decided to give this app a try and I love it. I've never tried any other online mah jongg games so I can't make a comparison, but I don't need to look any farther. This app is easy to use and fun to play. Highly recommended!
