General
The five chess piece types are ranked from highest to lowest: King, Queen, Rook, Bishop, Knight.
Each card in the Mate deck depicts one of five chess piece types. These pieces are ranked from highest to lowest as follows: King (highest), Queen, Rook, Bishop, Knight (lowest). Rank determines which card wins a trick when both cards share the same color.
General
The four card colors are ranked from highest to lowest: Blue, Green, Yellow, Red.
Each card in the Mate deck is printed in one of four colors. Colors are ranked from highest to lowest as follows: Blue (highest), Green, Yellow, Red (lowest). Color rank determines which card wins a trick when a player cannot match the led color and plays a different color, and also resolves ties when rank is matched.
Setup
Mate uses a 20-card deck in either Single or Double Mate format, with five piece types in four colors.
The Mate deck contains twenty cards total, available in two formats: Single Mate and Double Mate. Each card shows one of five chess piece types (King, Queen, Rook, Bishop, Knight) in one of four colors (Blue, Green, Yellow, Red). Players choose which format to use before preparing and shuffling the deck.
Setup
Shuffle the 20-card deck, randomly select a dealer, and deal 10 cards to each player.
After preparing the deck in the chosen format, shuffle it thoroughly. Randomly determine which player will deal. The dealer deals ten cards to each player. All ten cards constitute that player's hand for the round. The dealer leads the first card to begin the round.
Turn structure
The player with the lead begins a trick by playing any card from their hand.
The player who holds the lead starts a trick by playing any card of their choice face up in front of them. The dealer has the lead at the start of the round. The lead is retained by the trick winner until the round ends or the lead is lost.
Turn structure
The second player must follow the color of the led card if able.
When the leading player plays a card, the opposing player must play a card of the same color if they have one in their hand. This is called 'following color' and takes priority over following rank. If the player has at least one card of the led color, they must play one of those cards.
Turn structure
If unable to follow color, the second player must follow rank (play a card of the same piece type).
If the non-leading player has no cards of the led color, they must instead play a card of the same piece type (rank) as the led card. For example, if a Rook is led and the player has no cards of the led color, they must play a Rook of a different color if they have one.
Turn structure
The highest rank within a color wins, or the highest color when ranks are matched; the winner takes the lead.
After both cards are played, the trick is resolved as follows: (1) The player who played the highest-ranked piece within the led color wins the trick. (2) If rank has been matched (both players played the same piece type), the player who played the highest-ranked color wins. The trick winner takes the lead for the next trick.
