How to Play Block Dominoes: Complete Rules for Beginners

Block dominoes is the game most people picture when they hear the word "dominoes" — no hands drawn mid-round, no wild tiles, just a line of matching numbers growing across the table until someone runs out of moves or runs out of tiles. It's also the ancestor of most other domino games, so learning it well makes every variant easier to pick up later. This guide covers block dominoes specifically — the version with a sealed boneyard and no mid-round drawing. Other domino games borrow its core mechanics but change the details, sometimes significantly, so treat this as one well-defined game rather than "the" universal rules of dominoes.

What you need

A standard double-six set has 28 tiles, covering every pair of numbers from 0-0 up to 6-6, with no number repeated between two-player games. Two, three, or four players can play; two players is the classic configuration for block dominoes specifically, though the same rules extend to more with a bigger set. Larger sets — double-nine (55 tiles) or double-twelve (91 tiles) — work the same way and are common choices once more than four people want a hand each; the full breakdown of every set size is in our Domino Set Reference.

A few terms worth knowing first

The vocabulary below shows up constantly once you start reading domino rules or playing with an experienced group, so it's worth having it down before the first tile gets shuffled:

• Bones or tiles. The individual pieces — either word is fine, and long-time players tend to use them interchangeably.
• Pips. The dots on a tile's face. A "3-4" tile has 3 pips on one half and 4 on the other, for 7 pips total.
• Ends. The two open numbers at either extreme of the layout that a legal tile has to match.
• Spinner. The first double played, once it's been built on from all four of its sides so the layout branches in more than one direction from that point.
• Boneyard (or stock). The face-down tiles nobody was dealt. In block dominoes it just sits there for the whole round; in draw dominoes, players pull from it whenever they're stuck.
• Domino (verb). To play your last tile and empty your hand, ending the round outright. "Going out" means the same thing.

Setting up

Turn all 28 tiles face down and shuffle them by sliding them around the table (this is often called "washing" the bones). For a two-player game, each player draws 7 tiles into their hand, keeping them hidden from the opponent. The remaining 14 tiles form the boneyard, left face down and set aside — in block dominoes, unlike draw dominoes, the boneyard stays untouched once play begins.

Seven tiles for two players is a deliberate choice, not a maximum: a double-six set could technically deal each of two players up to 14 tiles apiece with nothing left over (that's floor(28 ÷ 2), the mathematical ceiling covered on the set reference page), but dealing that many would leave no boneyard at all and make the opening hand unwieldy. Seven is the customary middle ground — enough tiles to have real choices on your turn, with half the set still held in reserve.

With three or four players, the same "deal enough for a real hand, keep some in reserve" logic applies, though exactly how many tiles each player gets is one of the details that varies most by house rule and region — some groups deal 7 to everyone regardless of player count (which uses all 28 tiles with 4 players and no boneyard at all), others deal fewer to keep a boneyard in play even at a full table. Agree on the hand size before shuffling if it isn't already your group's habit.

Who goes first

The traditional opener is whoever holds the highest double in their hand — the 6-6 if someone has it, otherwise the highest double that was actually dealt. That player lays it in the center of the table to start the line. If no one holds a double, the highest single tile (by combined pip count) leads instead. After the first game, the winner of the previous round typically leads next, which keeps the "highest double" hunt from happening every single round.

Making a move

Play proceeds clockwise. On your turn, you must place one tile from your hand so that one of its ends matches a number already open at either end of the layout — a 3 can only be placed against another 3. The layout can grow in either direction, and after the first double is played, later doubles are placed crosswise, opening up a branch that both ends of the line can then extend from.

If you have no tile that matches either open end, you simply pass your turn — there's no tile to draw from in block dominoes, since the boneyard is off-limits during play. Play continues clockwise to the next player. A pass costs you nothing directly, but it does hand information to the table: everyone now knows you're holding no tile for either currently open number, which is exactly the kind of clue our guide to reading the boneyard and tracking what's likely still unseen builds on.

How a round ends

A round ends one of two ways:

• Someone dominoes. A player plays their very last tile, winning the round outright.
• The game blocks. No player at the table has a legal move on their turn, and play cannot continue. Every remaining player's hand is revealed and totaled by pip count; whoever holds the fewest pips wins the round.

For how those two endings translate into points, see our companion guide on domino scoring and try the numbers in the Domino Scorekeeper.

A worked example

Say two players, Ana and Ben, are dealt 7 tiles each from a double-six set. Ana holds the 5-5 double and leads with it. Ben has a 5-3, so he plays it against one end of the 5-5, opening a "5-3" edge and leaving the other end of the double still open at 5. Ana now needs a tile with a 5 or a 3 on it; she plays a 3-1, extending the layout to 5-3-1, with the open ends now at 1 and (still) 5 on the other side of the double.

Ben has no 1 and no 5 left in hand, so he passes. Ana plays a 5-2 against the open 5 on the double's other side, and now the layout has three open ends in play — 1 at one tip, 2 at the far side of the spinner, and the original 5-3 edge is now closed off by nothing new, so it's really down to whichever ends are currently exposed at the two growing tips plus the spinner's remaining side. Ben draws no tiles (there's no drawing in block dominoes), and if his remaining hand has nothing matching 1, 2, or whatever the spinner's last open side shows, he passes again.

Play continues this way, both sides drawing down their hands, until either someone empties their hand first (a domino) or a turn comes around where neither open number — whatever they happen to be at that point — matches anything left in the active player's hand, and neither opponent can move either. At that point the round blocks, hands are revealed, and pip totals decide the winner.

Common beginner mistakes

• Forgetting doubles play crosswise. A double isn't just "a tile with matching numbers" — once placed, it typically turns 90 degrees to the line and can be built on from its other two open sides, not just extended in a straight run.
• Playing on the wrong end. Only the two currently open ends of the layout are legal targets; a tile can't be slotted into the middle of an existing line.
• Not passing when you should. If you truly have no legal tile, you must pass rather than play an unmatched tile "close enough."
• Treating a pass as "nothing happened." A pass tells the rest of the table exactly which two numbers you're empty on right now — strong players remember every pass, not just every play.
• Losing track of your own pip total. If the round blocks, the tiles still in your hand count against you. Glancing at your own remaining pip count as the hand thins out helps you judge whether forcing a block would actually work in your favor — the subject of our guide to defensive play and counting pips.

Playing with more than two

The core rules don't change with a bigger table — turns still move clockwise, and the same match-the-open-end requirement applies — but two things are worth planning for. First, agree on hand size up front, since it isn't as universally fixed as the two-player deal (see above). Second, remember that with more players, more information becomes public faster: three or four sets of passes accumulate information about which numbers are scarce far quicker than in a two-player game, which makes tracking passes even more valuable at a fuller table.

Where to go from here

Once block dominoes feels natural, draw dominoes is the next logical step — the same core rules, but players draw from the boneyard when they can't play instead of passing immediately, which changes the pacing and the odds considerably (our draw-odds guide covers exactly how those odds work). From there, regional games like Mexican Train and Chicken Foot layer on their own twists, covered in our comparison guide. Whatever variant you land on, the fundamentals here — matching ends, playing doubles crosswise, and totting up pips at the finish — carry through almost everywhere.
