With four bonus games by Néstor Romeral Andrés
INTRODUCTION
Dominoes is a traditional tile game played in many different cultures around the world; thestandard set being the 28-tile "Double Six" set.
Double-seven binary-coding hexdominoes includes 36 tiles (with numbers from 0 to 7)composed of two adjacent hexagons. Instead of the standard ‘pips’, this set uses a special
concentric binary representation. A central pip equals 1, a small circle equals 2 and a bigcircle equals 4.

Example: The 3-6 tile
Play dominoes as usual, but each player is dealt 9 tiles instead of 7.
This rulebook includes some games that can be played with the set, designed by yourstrully.

HEXDOMINUP
Hexdominup is a game for 2 to 4 players, derived from Dominup, by the same designer.
There are two types of placements in Hexdominup. In both cases the tile must be alignedwith an imaginary hexagonal grid:-‘Climb’ placement: The tile is placed atop two adjacent tiles of the same level, so thatthe numbers (symbols) of the placed tile match the symbols underneath (one of eachsupporting tile).

Example of a valid ‘climb’ placement-‘Expand’ placement: The tile is placed on the table and adjacent to at least one tile
already placed. The values of adjacent hexagons don’t need to match.

How to play
Randomly distribute the tiles face-down evenly among the players (as in dominoes).
The player with the double-7 starts by placing it in the middle of the playing surface.
Starting with the second player, players take turns in anticlockwise order doing all of thefollowing steps in order until the game end condition is reached:
1. If you can make a climb placement with at least one of your tiles, then you must
do so. You can choose which tile to place, as long as the placement is legal.
Repeat this action until you can’t make any more climb placements.

2. If you have at least one tile left, then make one expand placement.
If, at the end of your turn, you have no tiles left, then you’ve won and the game ends.
However, the other players can continue playing to determine 2nd, 3rd, and 4th place if theywish.
Variant: Misere Hexdominup. In this variant, the player who runs out of tiles first loses.

HEXDOMINOMEGAHexdominomega is a game for exactly 3 players derived from Dominomega, by the same
designer. It is the result of applying the multiplicative scoring of OMEGA to this dominoes
set.
Each player has an allocated symbol (pip, small circle or large circle). Before the gamestarts, shuffle all tiles face down. Each player draws one tile (don't show it to the otherplayers).
Starting with the 'pip' player, players take turns (pip - small circle - large circle) placing their
tile on the table and adjacent to at least one previously placed tile if any, so that the tiles fit
into an imaginary hexagonal grid, then drawing a new playing tile from the supply (ifpossible). The values of adjacent tiles don’t need to match.
Once all the 36 tiles have been placed, players calculate their score:
To calculate your score, multiply the sizes of all groups of hexagons (half tiles) containing
your symbol. Notice that some half tiles contain several symbols (example: the number 7
contains all three). Notice also that each symbol is present exactly 36 times. The player
with the highest score wins. The maximum possible score is 531441.

Endgame example. The ‘Small Circle’ player scores
25 x 4 x 1 x 1 x 1 x 4 = 400 points.
Variant for 2 players: The small circle is not allocated to any player (but still can win!).

HEXDOMINIMUM
Hexdominimum is a derivative of Mystique Energy and Dominimum (by the samedesigner) that can be played with this dominoes set. Hexdominimum is for 2 to 4 players.
To set up, shuffle the tiles face-down on the table. Each player then draws a tile without
showing it to the other players, looks at it, then places it standing up before them so theother players can’t see it. If both symbols are the same (i.e. it is a double tile) then discard
the tile to the supply and re-draw until you get a tile with two different symbols; thenreshuffle the supply. This is your "mission tile". Each player then draws a second tile; this is
your "playing tile".
The first player places her playing tile on the table face-up. Then, starting with the second
player, players take turns in anticlockwise order, placing their playing tile on the tableadjacent to at least one placed tile so that the tiles fit into an imaginary hexagonal grid,then drawing a new playing tile from the supply (if possible). The values of adjacent tiles
don’t need to match.
The game ends when the last tile has been placed on the table, and each player thencalculates her score. For each of the two symbols on your mission tile, find the largest
contiguous, connected group of that symbol. Count the number of hexagons in that group.
Once you have counted the largest group for each of your two symbols, multiply these twovalues to determine your score.
The player with the lowest score wins. In case of a tie, the tied player who played her final
tile first wins.

Example: The player with the 1-5 mission tile (green) scores 3×5=15 points

HEXTRAHextra is an upgrade on Dominoes for 2 to 4 players.
Shuffle the tiles facing down and deal all them evenly among the players. Each player
places her tiles standing up before her so the other players can’t see them (as inDominoes).
The player with the double blank starts by placing any tile in the middle of the playing
surface.
From now on, starting with the second player, players take turns in order placing a tile
adjacent to a previously placed tile so that at least one of its values matches the value of
its adjacent hexagon (this is, you must create a new pair of equal symbols). The tile can beadjacent to more than one placed tile. Consider the imaginary hexagonal grid as always. Ifnone of the player’s tiles can be legally played then she passes the turn (this is very rare).

Examples of valid placements (green):
At least two adjacent symbols match(even if touching other tiles).
Additionally, if each of the two symbols of the newly placed tile match with adjacentsymbols of different tiles, the player gets an extra turn. As a result of this, the player mightachieve a chain of extra turns.

Notice that if both symbols of the new tile match with the same hexagon of an alreadyplayed tile, no extra turn is awarded:
