Hidden Trump
A 4‑player partnership card game with a twist — the trump suit stays secret until an opponent forces the reveal. Out‑bid, out‑bluff and out‑play the AI.
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.

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

Capture the Pile
Go “Senior Twice” after the reveal to claim stacked tricks and score Sets.
All 13 Rules — in plain words
The complete rulebook, rewritten so anyone can jump straight in.
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.
The Secret Trump
The top bidder hides one card as trump. Nobody sees its suit until an opponent forces a “Reveal”.
When Trump Works
Trump cards only beat other suits from the moment of the Reveal onward. Before that, they’re just normal cards.
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.
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.
Defense Exception
If an opponent is about to win and your 2nd Ace can stop them, it keeps full power to protect the pile.
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.
Help Your Partner Finish
Teammates work together to empty a suit. The AI leads the suits your partner is trying to clear.
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.
Attack After Reveal
Once trump is out, everyone plays hard — top cards and trumps come out to win tricks and the pile.
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.
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.
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.
