Why it helps

You'll experience the view from a real table, with support as you get used to it.

Practise this lesson

Let's try the view you'll have at a real table. Your opponents' hidden tiles add some uncertainty, but you still have clues to work with.

Play with your opponents' tiles hidden

At a real table, you see your own tiles, everyone's exposures and the discards. You don't see the tiles your opponents keep behind their racks.

You can get used to that view here, with the Coach and Undo still available when you want them.

Read what the table shows you

An exposure narrows the rows an opponent could be building. Compare it with the card before discarding a tile those rows may need. One exposure may fit several rows, so it does not reveal their exact hand.

Use the discards as a record of tiles already played. Keep checking your own row as well: caution is useful, but you still need a complete hand to win.

Hidden racks do not require you to choose a concealed row. C is a separate rule on the card: no exposures until mahjong.

Keep practising

Take the game one turn at a time. Finishing completes the lesson, and any hints or undos are simply recorded as Help used.

At a physical table, say “wait” if you need to consider a discard. Speak before the next player racks, discards or starts an exchange confirm.

Remember

Use exposures and discards as clues. Keep checking your own hand against the card.
