Mahjong Demon XL

This is the only true Japanese Mahjong App that I have discovered since the days of Shanghai Second Dynasty, that was purchased to work with Windows 98 and XP that had a choice of different types of the Mahjong board games. My Mahjong expert friend concedes that the game is good except for the addition of the red five as a Dora yaku. He insists that the true Japanese Mahjong does not use the red five tile for an additional yaku. Now, the old laptop with XP OS will be put to rest. Old Timer

Best I’ve seen in a long time

Whilst not the greatest digital version of mahjong I’ve seen, it’s far and away the best version using Japanese scoring in the American App Store. Not only that but it’s the simple things like actually using the correct Japanese terminology (pon, kan, chi, etc) instead of Chinese terms (pung, kong, chow, etc) which makes a real difference when playing. I would like to see an English version of the rules and scoring but if you already understand this is a good app for you.

Good Game, but bugs are annoying

It’s the best Japanese mahjong game around, but a recent update or something make the background a large pass button. So if you have big fingers and select Ron but half your finger also touched the background - it passes instead of winning.

Very frustrating.

Also is there a way to make the background a solid colour?

Something is wrong.

Big problem.

The game doesnt allow me to "pon" ... The other 3 players go quickly and dont stop till my turn. No point in playing if can't pon or chi.
