This card game blends memory and strategic thinking. Gameplay revolves around minimizing the value of your hand.

A round begins with each player receiving four face-down cards. Initially, each player can view their two rightmost cards. All cards remain face-down throughout the game.

On your turn, you have three choices:

1. Replace the center card: Exchange a card from your hand with the center card.
2. Replicate a card: Duplicate an existing card in your hand.
3. Draw a card: Draw a card from the deck. You may then replace one of your cards with the drawn card or discard the drawn card.

Special cards add layers of complexity:

• 7 and 8: Allow you to view one of your own hidden cards.
• 9 and 10: Allow you to view one card from another player's hand.
• Eye Master: Lets you see one card from each opponent's hand, or view two of your own cards.
• Swap: Allows you to exchange one of your cards with another player's card without revealing the cards.
• Replica: Enables you to discard any card from your hand.

The round continues until a player calls "Skru." This player forfeits their turn, and the round ends after all other players take one more turn. Calling "Skru" is prohibited within the first three turns.

At the round's conclusion, all cards are revealed. The player(s) with the lowest total card value receive(s) a score of zero. If multiple players tie for the lowest score, they all score zero. Crucially, if a player calls "Skru" but does not have the lowest score, their score is doubled.
