Coinche

Coinche

The French auction card game. Bid your hand, pick your trump, make your contract — or watch your opponents double you into oblivion.

What is Coinche?

Coinche is a partnership trick-taking card game popular across France and Eastern Europe. It's a variant of Belote with auction bidding, players bid a point value and trump suit, and opponents can Double (Coinche) or even Redouble (Surcoinche) to raise the stakes.

How to Play

• 4 players, 2 teams — you and your partner (GHOST) vs two AI opponents (RAVEN & COBRA)
• 32-card deck — 7 through Ace in each suit
• Auction phase — bid 80–160 points + a trump suit, or go for CAPOT (all 8 tricks)
• Trick-taking — must follow suit, must trump if you can't follow, must overtrump if possible
• Trump card values — Jack (20), Nine (14), Ace (11), Ten (10), King (4), Queen (3)
• Scoring — make your contract to score card points + bid value. Fail and your opponents take everything.
• Double & Redouble — opponents can double your bid. You can redouble right back. High risk, high reward.
• First team to 1000 points wins.
