Dominoes are simple to learn and a lot of fun. Below is a clear guide to the most common way to play a standard “domino” game, plus quick notes for variations. Direct answer

• Objective: Be the first to empty your hand or score the most points by making valid plays until the game ends.
• Setup: Use a standard double-six domino set (28 tiles). Shuffle face down and draw a人数 matching your game version (commonly 7 tiles each for 2 players, 5 for 3–4 players). Place the remaining tiles as a draw pile.
• Start: The player with the highest double (or, if none, the highest tile) starts by placing that domino in the center of the table.
• Play: Players alternate turns, placing a tile that matches a number on either end of the existing chain. Doubles are usually played perpendicular to the line and can sometimes be started or continued from multiple ends depending on the variation.
• Rules for matching: A played domino must share a matching number with at least one exposed end of the chain.
• Drawing: If a player cannot move, they must draw tiles from the draw pile until they can play (in some variants, drawing is only allowed when no moves are available).
• Ending: The hand is finished when a player has no tiles left, or when no players can make a move and the draw pile is exhausted.
• Scoring (optional variants): In many versions, points are scored per round by counting pips on a player’s remaining tiles (or the total pips of the winner’s hand subtracted from others’ hands). Other common scoring methods use the total pips on the remaining tiles of all players as a penalty for blocking.

Common variants you might encounter

• Block dominoes: If you’re blocked, you pass your turn (no drawing from the pile).
• Draw dominoes: If you can’t move, you draw from the pile until you can play or until the pile is exhausted.
• Mexican Train: A popular variant where the first player starts a “train,” and players must extend off of their own trains or the central train with multiples, often using a spinner (the first double played) to allow branching plays.

Quick tips for new players

• Plan ahead a couple of moves, especially when doubles are in play.
• Keep your high-value tiles to the end if possible, so you’re not left stuck with them.
• If you can, try to force opponents to draw by creating chains with scarce matching numbers.

If you’d like, I can tailor these rules to a specific version (two-player classic, Mexican Train, or a classroom-friendly variant) or give you a printable quick-start guide.
