The information on playing cards.

The “three-suited” version of game has the original set of playing cards and exist independently of playing cards which are grouped in four suits, because the set consist of three suits as well.
In principle card sets can also use five or six suits, but the abundance of suits makes card games difficult.
The three suits correspond to three different colors, i.e. the playing cards are marked as red, yellow, green.
The three-suited version has three decks of playing cards each of them being comprised of three suits and each suit is comprised of 6 values from 1 to 6; in other words each deck has 3x6=18 playing cards and three decks are comprised of 18x3=54 playing cards in total.
Players can distinguish playing cards of different decks by the presence or absence of various circles on the backs and faces.
The values are multiplied by ten in the second deck, i.e. numbers are followed by a zero; and the values are multiplied by hundred in the third deck, i.e. numbers are followed by a double zero. This allows the players to use playing cards as if they have either equal or different values.
Proportional groups of playing cards in each deck are marked with points on the backs and faces. Each deck is comprised of three proportional groups, namely each proportional group being comprised of 6 playing cards.
The three-suited playing cards can be used if the number of players is a multiple of three according to the combinatorial construction. Each player can play with own deck or with playing cards forming a proportional group in one deck.
Also the playing cards are marked with arrows showing their orientation, so players can orient cards on the game board.
It is desirable to use the game board which has 9 columns and 6 rows. The rows are notated by numbers which correspond to values of playing cards. Columns are marked with different colors corresponding to suits of playing cards.
The game board is comprised of 6x9=54 squares and in the three decks there are also 54 playing cards, i.e. each playing card can be placed on a correspondent square.
The game board is comprised of alternating dark and light squares, and 1/3 of the squares are highlighted, because this is necessary in rules of some games.
The three-suited playing cards are enjoyable if the number of players is a multiple of three, i.e. if there are 3 or 6 or 9 players who can have equal chances to win if playing cards are open on the game board.

The three-suited version of game holds the patent of invention RU2243800, and this version of game can be manufactured independently from four-suited playing cards if somebody is interested in manufacture.
