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

Each round begins with four face-down cards dealt to each player. Initially, each player can only 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 central card.
2. Replicate a card: Duplicate one of your cards.
3. Draw a card: Draw a card from the deck. You can then either replace one of your cards with the drawn card or discard the drawn card.

Certain cards possess special abilities:

• 7 and 8: Allow you to view one of your own 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, or two of your own cards.
• Swap: Enables you to exchange one of your cards with another player without revealing the cards.
• Replica: Allows you to discard any card from your hand.

The round continues until a player calls "Skru." This player forfeits their turn, and the round concludes after each remaining player takes one more turn. Calling "Skru" is prohibited within the first three turns.

At the round's end, all cards are revealed. The player(s) with the lowest total card value receive a score of zero. If a player calls "Skru" but doesn't have the lowest score, their score is doubled.
