🎯 About Dominoes
Dominoes is one of the world's oldest and most beloved board games, with origins tracing back to 12th century China. This Block Dominoes variant is the most popular form of the game worldwide, combining simple rules with deep strategic gameplay.
Using a standard set of 28 double-six dominoes (tiles numbered 0-0 through 6-6), two players compete to be the first to play all their tiles. Each domino has two ends with dots (called "pips") representing numbers from 0 to 6. The game requires pattern recognition, strategic thinking, and counting skills - making it perfect for both casual play and competitive matches.
🎮 How to Play Block Dominoes
Game Setup
- 28 Tiles Total: A complete set contains all combinations from 0-0 to 6-6 (28 unique tiles)
- Starting Hand: Each player draws 7 tiles face-down from the shuffled boneyard
- Opening Move: Player with the highest double (6-6, 5-5, etc.) starts, or draw highest tile if no doubles
- Remaining Tiles: The 14 unused tiles stay face-down as the boneyard (not used in Block Dominoes)
Basic Rules
- Matching Numbers: Place a tile so one of its ends matches a number on either end of the domino chain
- Chain Building: The chain grows from both ends as players add matching tiles
- Doubles Placement: Double tiles (e.g., 3-3) are placed perpendicular to the chain
- Must Play: If you have a matching tile, you can play it (though in Block Dominoes, passing is allowed)
- Passing: If you cannot or choose not to play, you must pass (no drawing from boneyard)
- Game End: Game ends when one player plays all tiles OR both players pass consecutively (blocked game)
Scoring System
Domino Out (Win by emptying hand): Score equals total pip count in opponent's remaining tiles
Blocked Game (No one can play): Player with lowest pip count wins and scores the difference between hands
Target Score: First player to reach 100 points (or 150 in longer games) wins the match!
🎯 Winning Strategies for Dominoes
1. Play Doubles Early
Doubles (0-0, 1-1, 2-2, etc.) are the hardest tiles to play since they only match one number. Play them early while you still have flexibility. Getting stuck with doubles at the end can cost you 10-12 points!
2. Count Suits & Track Played Tiles
There are exactly 7 tiles containing each number (e.g., seven tiles with "3": 0-3, 1-3, 2-3, 3-3, 4-3, 5-3, 6-3). Track which numbers have been played heavily - if 6 out of 7 "fives" are on the table, playing a 5 might block your opponent who likely has that last five!
3. Control the Chain Ends
Strategic players try to create chain ends with numbers their opponents lack. If the AI keeps passing on "twos," try to keep one end showing a 2 to force them to pass again. This is called "blocking" strategy.
4. Keep Versatile Tiles
Tiles like 3-4 or 2-5 that connect two different common numbers are extremely valuable. These "connector tiles" give you options when the chain ends change. Save them for crucial moments when you need flexibility.
5. Minimize High-Value Tiles
In Block Dominoes, you can't draw more tiles. Prioritize playing high-value tiles (6-6, 6-5, 5-5) early to reduce your pip count. If the game gets blocked, high pips in your hand cost you points!
6. Force Passes with Rare Numbers
Once you've seen most tiles with a certain number (say, five out of seven "fours"), placing a 4 on the chain end likely forces a pass. This advanced tactic gives you control and extra turns.
📊 Dominoes Math & Probabilities
Tile Distribution
- Total Tiles: 28 tiles in a double-six set
- Tiles per Number: Each number (0-6) appears on exactly 7 tiles
- Total Pips: Sum of all pips = 168 (average 6 pips per tile)
- Doubles: 7 double tiles (0-0 through 6-6) worth a total of 42 pips
Probability Insights
Chance opponent has a specific number: If you hold 3 tiles with "fives," there are 4 remaining fives among 21 unknown tiles (19% chance opponent has any specific five)
Blocking probability: If 6 out of 7 tiles containing "three" are visible, there's an 85% chance the last "three" is in opponent's hand, making it a strong blocking number
🆚 Dominoes Variants Comparison
| Variant | Drawing Rule | Difficulty | Best For |

| Draw Dominoes | Draw from boneyard if can't play | Easy-Medium | Beginners, casual play |
| Muggins/All Fives | Score when chain ends total multiples of 5 | Hard | Math-oriented players |
| Mexican Train | Multiple chains, draw from boneyard | Medium | Groups of 3+ players |
🏆 Advanced Dominoes Tactics
The "Branching" Strategy
When you have multiple tiles of the same number (e.g., three tiles with "fours"), you control that suit. Use this to your advantage by keeping both chain ends showing fours - your opponent likely can't match either end!
Pip Counting Endgame
In the final stages, mentally calculate your hand's pip count versus the opponent's (estimate based on their tile count and plays). If you're ahead, try to force a blocked game. If you're behind, risk going out even if it means giving opponent an extra turn.
Defensive Doubling
Sometimes playing a double (e.g., 2-2) limits the chain to only one number, making it harder for your opponent to play. This defensive tactic is useful when you suspect they lack that number.
Opening Move Strategy
The highest double (6-6) is traditionally the opening tile. However, in competitive play, some experts prefer playing a lower double (like 4-4) with the highest tile first, keeping high-value tiles in reserve for scoring.
❓ How do you play Dominoes?
Each player draws 7 tiles from a face-down boneyard. Players take turns placing tiles that match the numbers on either end of the domino chain (e.g., place a 3-5 tile next to an exposed 3 or 5). If you can't play, draw from the boneyard until you can play or it's empty. First player to play all tiles wins, or if blocked, the player with lowest pip count wins.
❓ What is Block Dominoes?
Block Dominoes is the most popular dominoes variant. Players cannot draw from the boneyard once the game starts - you must play from your initial 7 tiles. If you can't match either end of the chain, you must pass. This makes it more strategic than Draw Dominoes since you can't replenish your hand.
❓ What's the best strategy to win at Dominoes?
Key strategies: 1) Play doubles early to avoid getting stuck with high-value tiles. 2) Count suits - track which numbers have been played to predict opponents' hands. 3) Block opponents by playing numbers they seem to lack. 4) Save tiles with multiple suits (like 3-4 if both 3s and 4s are common) for flexibility. 5) In Block Dominoes, force passes by creating chains with rare numbers.
❓ How is Dominoes scored?
In Block Dominoes, the first player to play all tiles wins and scores points equal to the total pip count in opponents' remaining tiles. If the game is blocked (no one can play), the player with the lowest pip count wins and scores the difference between all hands. Games are typically played to 100 or 150 points.
❓ What is a double in Dominoes?
A double is a domino tile with the same number on both halves (0-0, 1-1, 2-2, up to 6-6). Doubles are typically placed perpendicular to the chain. The highest double (6-6) is often the starting tile in traditional rules. Doubles are strategic since they only match one number, making them harder to play later.
❓ Can I play Dominoes on mobile?
Yes! This Dominoes game works perfectly on phones and tablets. Tap tiles to select, then tap a valid chain end to place. The game auto-rotates tiles if needed and highlights valid moves. All features including AI opponents, hints, and scoring work seamlessly on touch screens.

📚 History of Dominoes
Dominoes originated in China around 1120 AD during the Song Dynasty. Early Chinese dominoes represented all possible throws of two dice, explaining why traditional sets have no blank tiles and go up to double-six (the maximum dice throw).
The game spread to Italy in the 18th century (possibly through Marco Polo's travels or via trade routes), where the modern 28-tile set was standardized. The word "domino" likely comes from the Latin "dominus" (master) or from black-and-white domino masks worn at Venetian carnivals.
By the 19th century, dominoes became popular across Europe and America. The game's simplicity and portability made it a favorite in taverns, homes, and military camps. Today, it remains one of the most-played games worldwide!
