Basic rules of Dominoes

The 28 tiles go from 0-0 to 6-6. With two players each takes 7 tiles, with three or four players 5; the rest is the stock.
In the first round, whoever holds the highest double (or else the heaviest tile) puts it down to start.
In turn, play a tile that matches either open end of the line. If you cannot, draw from the stock one tile at a time; with an empty stock, pass.
Whoever plays their last tile scores the dots left in everybody else's hands. If nobody can play, the lightest hand scores the others' dots minus its own.
Rounds go on until someone reaches the target score (50, 100 or 150; 100 by default), and the highest score wins.

How to play on Asobi Lounge

On your turn, the tiles you can play stand up. Press one to put it on the end it matches.
If a tile matches both ends, choose where it goes with the left end or right end button.
If you cannot play, press Draw (山から引く), or Pass (パス) when the stock is empty.

Tips

Play heavy tiles first, so you lose fewer points if someone goes out before you.
Leave ends you hold tiles for, so you can keep playing on your next turn.
Doubles have fewer places to go, so playing them early is a good idea.
