In dominoes what do you when no player can play?

When no player can play in dominoes, it's called a "block" or a "draw". Here's what happens:

1. The game ends. The round is over, and no one wins.

2. Scoring (if applicable):

* Some domino games have specific scoring rules for blocks. For example, the player with the lowest total value of dominoes left in their hand might win the round.

* Other games have no scoring for a block.

3. Starting the next round:

* The dominoes are shuffled and dealt again, and the game continues with a new starting player.

Important Note: There are many variations of dominoes, so the exact rules for blocks might differ depending on the specific game you are playing.
