🃏 Palace (aka Shed, Karma, or "OG") – Official Rules (Version 3.1.6)

Last Updated: August 7, 2024 | SDK-Compliant | Multiplayer Ready

🎯 Overview

Palace is a fast-paced, strategic shedding card game loved by students, backpackers, and casual gamers for decades. With simple rules and deep tactical depth, it's perfect for 2–6 players. Now with new gameplay mechanics, friend multiplayer, and smart AI opponents, it's more exciting than ever.

🃏 Setup (2–6 Players)

1. Shuffle a standard 52-card deck (Jokers optional; if used, remove them for classic play).
2. Deal 3 face-down cards to each player (these are your "hidden stash").
3. Place 3 face-up cards in the center (the "pile" or "discard pile").
4. Deal 3 cards face-up to each player’s hand.
5. Optional: Use the new “Pick Up the Pile Anytime” rule (see New Features below).

🎲 Starting the Game

• The player with the lowest rank card (3, 2, or 10 count as wilds) starts.
• If multiple players have a 3, the lowest suit (Spades breaks the tie.
• If no 3 exists, any player with the lowest non-wild card may begin.

⚠️ New in 3.1.6: The player who starts may declare a "challenge" to any opponent who plays a 7. See "7 Forcing Rule" below.

🃏 Basic Gameplay (Turn Order)

On your turn, you must:

1. Discard one or more cards from your hand equal to or higher than the top card of the pile.
   • Example: If the top card is a 7, you can play a 7, 8, 9, 10, J, Q, K, A, or a wild (2 or 10).
2. You may play multiple cards of the same rank (e.g., two 8s).
3. After discarding, draw from the deck to maintain at least 3 cards in your hand (unless deck is empty or you already have 3 or more).
4. If you can’t play, you must pick up the entire pile.

🌪️ Special Cards & Wilds (Key Rule Changes in 3.1.6)

✅ New in 3.1.6 – "Pick Up the Pile Anytime" Rule

• If you cannot play, you may optionally choose to pick up the pile immediately, even if you're not forced to.
• This lets you strategically take control of the pile to block others or draw better cards.
• Only one player can pick up per turn — the first to act wins.

✅ New in 3.1.6 – 7 Forcing Rule

• If a player plays a 7, any opponent may challenge them immediately.
• The challenger says: "I challenge you on that 7!"
• The challenged player must show their hand — if they have a card lower than 7, they must pick up the pile.
• If they have no card lower than 7, they win the challenge and may keep the 7.
• Purpose: Prevents bluffing and adds psychological depth. Great for live play with friends.

📦 Card Management: The Three Stacks

Players manage three stacks:

1. Face-up cards (3 cards) – These are visible and can be swapped with your hand at any time.
2. Face-down cards (3 cards) – Hidden. Cannot be looked at until your hand and face-up cards are gone.
3. Hand (3 cards, drawn from deck) – Standard play area.

Switching Rules (New in 3.1.6):

• You may swap any card from your hand with any face-up card at the start of your turn, before playing.
• You can only do this once per turn, and only once per stack (e.g., swap one hand card with one face-up card).
• You must keep at least 3 cards in your hand after swapping.

🔄 Example: You have a 6 in your hand, but a 9 in face-up cards. You swap them to get a 9 in hand and a 6 face-up.

🎯 Winning the Game

• You must get rid of all your cards.
• Play order:
  1. Hand (3 cards) → 2. Face-up cards → 3. Face-down cards
• Once your hand and face-up cards are empty, you must play from your face-down stack, one at a time.
• You cannot shuffle or reorder your face-down cards.
• The first player to play their last card wins.

💡 Pro Tip: Save wild cards (2s, 10s) and 7s for when you're close to winning — they’re your ace in the hole.

🎮 Game Modes (New in 3.1.6)

🔄 Single Player Mode – Face Off Against 8 Unique AI Opponents

🧠 Strategic Tips (Version 3.1.6 Pro Play)

• Save 2s and 10s — they’re game-changers.
• Use 7s to pressure others — they’re the only card that can trigger a challenge.
• Watch your opponents' face-up cards — if they’re about to go empty, they might swap to hide a low card.
• Don’t waste 4-of-a-kind unless you’re winning — it clears the pile and gives your opponent a fresh start.
• Use "Pick Up Anytime" to disrupt momentum — it's a tactical move, not just a safety net.
