How to Play Mah-Jong 300
Quick start
Open the first layout and inspect the uncovered edge tiles. Select two matching free tiles, watch what they uncover and plan the next pair before clearing more. If a choice exposes two different layers, compare which removal opens more space.
Controls
Use the stylus to select free tile pairs in Standard and the other pair modes. In Match, select the single tile requested by the displayed target. Remember reveals symbols briefly, while Shuffle and Countdown have their own clocks; read the active mode before using the available hint.
Mah-Jong 300 — About this game
Mah-Jong 300 uses layered tile matching but changes what you watch through five modes. Standard rewards clearing pairs efficiently, Countdown adds a board timer, Remember briefly reveals symbols, Shuffle pressures you to find the next pair before the layout changes, and Match asks for a displayed target tile. Begin in Standard with an available layout and learn which edge tiles are free. Compare a pair's effect on the covered layers before removing it, then try one alternate mode and read its timer carefully. Tile designs and difficulty options change presentation and challenge while the central task remains identifying the permitted matching pieces. Begin with the opening instructions and practice the main interaction before pursuing optional rewards. Read the current objective, make one deliberate choice and watch its effect before repeating it. A short first session makes it easier to separate a missed instruction from a difficult challenge. Return to the available menu when you need to check progress or adjust your approach, then continue from the next clear objective.
