Editing Dominoes (section)

===Blocking game===
The most basic domino variant is for two players and requires a double-six set. The 28 tiles are shuffled face down and form the ''stock'' or ''boneyard''. Each player draws seven tiles from the stock. Once the players begin drawing tiles, they are typically placed on-edge in front of the players, so players can see their own tiles, but not the value of their opponents' tiles. Players can thus see how many tiles remain in their opponents' hands at all times.

One player begins by downing (playing the first tile) one of their tiles. This tile starts the line of play, in which values of adjacent pairs of tile ends must match. The players alternately extend the line of play with one tile at one of its two ends; if a player is unable to place a valid tile, they must continue drawing tiles from the stock until they are able to place a tile. The game ends when one player wins by playing their last tile, or when the game is blocked because neither player can play. If that occurs, whoever caused the block receives all of the remaining player points not counting their own.<ref name="hoyle1950" />

====Middle Eastern version====

A common variant of the blocking game that is played in the Middle East features four players with slightly altered rules. The stock is divided equally on all players, each having seven tiles in hand. After drawing the tiles, the player with the double-six tile starts by downing that tile on the table and the game then proceeds counter-clockwise.

Since there is no boneyard, a player without a matching tile passes their turn. A player that is unable to play is called a downed or sitting player. A less common alternation of the middle eastern game requires the player to the left of the sitting player to transfer one of their tiles (not necessarily playable) tile to the downed player. In this variant, if the transferred tile can be played, they have to down it.

Similar to a normal blocking game, the game ends when a player empties their hand or the game is blocked. If the game is blocked, the player with the lightest hand receives points equal to the sum of all losing players' hands. A set of games ends when any player reaches a set amount of points, in which they win. If no player reached a winning score, the winning player from the previous round starts the next game with any tile in their hand and the game proceeds normally.

====Latin American version====
Another variant of the blocking game is the Latin American version and is played in teams of two. The stock is divided equally among all players, each having seven tiles in hand. Players sitting on opposite ends of the table are part of the same team.

The game ends when one of the players has no tiles left or when the game is blocked. In the first case, the team of the player without any tiles left earns the sum of the points left in the opposing teams' hands. When the game is blocked, the team with the least points in its hands earns the points left in the opposing teams' hands. If both teams have the same points, the team that started wins the round.
