The principal features of these dominoes type
games are the facts that digits are applied upon playing elements
(pieces, tiles, printed cards). Nevertheless, the dominoes principles can be realized
in different ways, and it means that these digits can be applied upon
playing elements in different ways. If dominoes tiles have four
sides, when digits are applied on four sides of each tile, these
elements can be named as quadradominoes (quadrilateral dominoes or quadraminoes,
or tetraminoes).
Standard quadradominoes set, which consist of 24 playing elements with
digit combination from 1 to 3, is the most optimal set for a human perception.
The proposed game package consists of two standard sets, which differ from
each other by presence/absence of dark circles placed on back sides of
quadradominoes tiles. They also differ from each other by circles of
different color and by contrast orienting arrows, which are located on
face surfaces of these quadrilateral playing elements.
The quantity of digits on playing element sides in each set is proportional
in relation to orienting arrows. It means that, if quadradominoes tiles are oriented
by arrows in the same one direction, elements are directed by proportional quantities of digits
in each of four directions.
Two colors of each element set mean proportional groups in
these set contents, which digits are oriented proportionally too.
It means, that these proposed quadradominoes sets have following design
feature: playing elements have proportional orientation of digits, and
at the same time quantity and orientation of red elements’ digits are
proportional to quantity and orientation of yellow elements’ digits in
the first set, and in the second set quantity and orientation of green
elements’ digits are proportional to quantity and orientation of blue
elements’ digits. Due to this arrangement each player can play with his
own set’s elements or with playing elements of his own proportional
group, which belongs to a content of any one set. In this case, if these
quadradominoes tiles are placed on the game board in accordance with
orienting arrows’ direction, players have equal odds to win and game
interaction is optimal. This is important, as a game that stands unbalanced
from the start, whether you're playing Monopoly or playing bingo online, is a fruitless
exercise for the player or players at the disadvantage.
The fact that these quadrilateral playing elements belong to proportional groups in content of
sets is designated by presence/absence of crosses on back sides of these
quadrilateral dominoes tiles.
The necessary game board is consisting of the 10 horizontal and the 8
vertical square rows. This game board gives possibility to place these
two sets’ quadrilateral elements in the initial playing positions in the manner which
is shown in figure 1, and also to place elements of two proportional
groups, which belongs to a content of any one set, in the manner which
is shown in figure 2.
These proposed playing positions are assigned only to demonstrate
possible element allocations. As a fact, they can have another
allocation. The quadradominoes digits are shown with help of Arabic
figures inside of schematic frames of the game board squares. Playing
elements orientation is shown with help of schematic arrows.
The board squares have numerical and letter designation. The light and
dark squares are alternated as in a chess. The game board central part is
marked by a contrasting color. It includes 48 squares, which quantity is
equal to quantity of playing elements in two sets.
Thus, the quadradominoes package includes two playing element sets, which
are arranged and designated in the special manner, and also has special
game board. And the board square structure is matched up with shape and
quantity of quadrilateral dominoes playing tiles.

I hope that
the offered gaming with quadrilateral dominoes will seem to you interesting!
