Let's play one whole hand together. Four players, each for themselves: Abuela, you, Lucía and Rafa, taking turns in that order. Everyone has seven tiles.
Your seven tiles.
66
Abuela holds the double-six, so she leads with it. Both open ends are 6.
62
Your turn. You play your 6-2, with the 6 against the double. The ends are now 6 and 2.
64
Lucía plays 2-4 on the 2. The ends are 6 and 4.
Rafa has no 6 and no 4, so he says “paso.” Remember that: everyone at the table now knows he's out of sixes and fours.
14
Abuela plays 1-6 on the left. The ends are 1 and 4.
14
You could play your 5-1, 6-4 or 4-4. You choose the double-four, because doubles are easy to get stuck with. The end is still 4.
Play keeps going around the table the same way: match an end or pass. Many turns later…
3···0
Both ends have grown: the ··· stands for all the tiles played in between. Lucía plays her last tile, the 6-0. ¡Dominó! The hand is over.
= 26
Everyone else shows what's left: Abuela 5-3, you 0-5, Rafa 5-5 and 2-1. 8 + 5 + 13 = 26 points for Lucía.
