Lookup
Enter your tiles to find every matching hand on the NMJL card. Spot overlapping alternates and sections of the card you might have overlooked.
Defense
What hand are they playing? Guess what your opponent is building from their exposed tiles. A new way to train your defensive eye.
Builder
Practice building every hand on the 2026 NMJL card. Tap tiles to match the hand at the top. Track your progress.
Why we are different
Standard mahjong table layouts don't translate to a small phone. Ours does. Tiles are large, the card sits right under your hand, and the moves you reach for most are one tap away.
See it in motion: the quick demo shows the basics, and the player's guide walks through the advanced practice features.
