About Quattuor Reges, from BoardGameGeek:
Quattor Reges is a game of chess, which means that it is a head-on battle where each player has moving pieces of different values.
The pieces represent the cards in a deck of 32 cards. One player controls Red (Heart and Diamonds), the other controls Black (Spades and Clubs).
The special feature of the game is a set of circular sockets. There are three groups of cards
A = Facets = King, Queen and Jack
B = small cards = 10, 9, 8 and 7
C = Ace
The figures (group A) capture all the small cards (group B). All small cards (group B) capture the Ace (group C). The Ace captures all the tricks (group A).
Inside the group of figures (A) there is also a circular hold: the King captures the Queen; the Lady captures the Jack; the Jack captures the King
Within the group of small cards (B), the catches are not circular but hierarchical: the 10 captures the 9, 8 and 7; the 9th captured the 8th and 7th; The 8 captures only the 7.
But there is a compensation that makes each piece interesting: all pieces can move 2 squares, but the 9 can move 3 squares and the 8 can move 4 squares. The 7 moves 3 squares and has the particularity of capturing the Jack (and not being captured by him).
Victory is achieved by reaching the last line of the opponent's side with one of these three pieces: a King, a Queen, or an Ace.
