Why it’s addictive

Classic trick‑taking, reimagined

Every round is a poker‑style mind game wrapped in a traditional card table.

🕵️

Hidden Trump

Pick a secret trump card. Its suit stays invisible until an opponent dares to force the reveal.

🎯

Bid to Win

An auction sets the target from 10–13 tricks. Bold enough? Bid 13 to start the round instantly.

🤝

Smart Partner AI

CPUs count every card, signal voids, lead to support you and protect the pile like a real teammate.

♠️

Senior Twice Pile

After the reveal, win two tricks back‑to‑back to scoop the whole stacked pile of tricks.

🃏

The Ace Rule

A back‑to‑back Ace drops to power 2 — unless you’re defending the pile. Timing is everything.

Master the table in a single round.

Deal & Bid

5 cards are dealt, players auction the target, then 8 more cards complete each hand.

Force the Reveal

Lead your shortest suits to pressure the hider into exposing the trump.

Capture the Pile

Go “Senior Twice” after the reveal to claim stacked tricks and score Sets.

No jargon, promise

All 13 Rules — in plain words

The complete rulebook, rewritten so anyone can jump straight in.

1
🃏

The Deal

You get 5 cards first and place a bid. After the trump is chosen, 8 more cards are dealt. Bid 13 and the round starts right away.

2
🕵️

The Secret Trump

The top bidder hides one card as trump. Nobody sees its suit until an opponent forces a “Reveal”.

3

When Trump Works

Trump cards only beat other suits from the moment of the Reveal onward. Before that, they’re just normal cards.

4
🏆

Senior Twice (The Pile)

Won tricks stack into a “pile”. To grab the whole pile, your team must win two tricks in a row after the trump is shown.

5
🅰️

The Ace Rule

Play an Ace, then another Ace next trick? The second one becomes a weak 2. Play any non‑Ace in between to reset it. Trick 13 is always full power.

6
🛡️

Defense Exception

If an opponent is about to win and your 2nd Ace can stop them, it keeps full power to protect the pile.

7
🪜

Lead Low When Senior

When you won the last trick, lead small cards to pull out the opponents’ big ones — and keep your Aces for defense.

8
🤝

Help Your Partner Finish

Teammates work together to empty a suit. The AI leads the suits your partner is trying to clear.

9
🔍

Force the Reveal

Opponents lead their shortest suits (1–2 cards) to make the hider show the trump. Partners join the attack when they’re senior.

10
🔥

Attack After Reveal

Once trump is out, everyone plays hard — top cards and trumps come out to win tricks and the pile.

11
🚫

Don’t Cut Your Partner

If your partner is already winning the trick with a high card, don’t waste your power. Save it for a trick you’re losing.

12
1️⃣

No Reveal on Trick 1

On the very first trick, no one can force a reveal. If you can’t follow suit, just discard any card.

13
🧮

Scoring & Resigning

Make your bid = your team scores it. Hiding team quits → others get double; others quit → hider gets the normal bid. Every 100 points = 1 Set.
