Books
Nine books, always in view
Every book sits along the top. Books you hold a card in stay lit, and won books move to the winning team’s side.
How it plays · 01
52 cards.
Nine books.
The deck splits into nine books. Each suit gives two books of six, two to seven and nine to ace, and the four eights make the ninth. You never play a card; you collect books.
How it plays · 02
Two teams.
One table.
Four, six or eight players split into Sapphire and Garnet. Teammates sit apart, so both your neighbours are opponents. The whole deck is dealt out, so every card is somewhere at the table.
Your turn · Ask
Ask for
one card.
Choose an opponent and ask for one exact card. The catch: you must already hold a different card from that book. Hold the 9♦, and you can ask for the K♦. If they have it, it comes to you, and you ask again.
Your turn · Miss
Miss,
and they play.
If they don’t have it, nothing moves and the turn passes to the player you asked. But the miss isn’t wasted: every ask is public, so the whole table learns something. Remembering is the game.
Your turn · Claim
All six?
Claim the book.
A book is won by claiming it, not by holding it. Once your team holds all six, spread between you however, claim it and lock it in. The J♦ you missed was with nila, your teammate, all along.
Your turn · Wrong claim
Claim too soon,
and it’s theirs.
A claim is a commitment. If even one card of the book sits with the other team, the whole book goes to them. Count carefully before you tap.
The win
First to
five books.
Nine books, so five wins it. Every ask gives you information, and every claim asks one question: are you sure?
