How to Play Koops

The goal

Your aim is to finish with a lower card value than every other player. Most cards remain face down, so good memory is as useful as good luck. Low cards help, removing a card makes its position worth zero, and power cards can reveal or exchange hidden cards.

Round setup

1. Two to eight players join a room. Computer opponents may fill seats in computer mode.
2. Each player pays the displayed entry fee into the round pot.
3. Every player receives four face-down cards.
4. Before normal turns begin, each player privately peeks at any two of their own cards once.
5. Remember the values and positions. The cards turn face down again.

Card values

Aces are worth 1. Number cards keep their printed value. Jacks are 11, Queens are 12, and Kings are 13. A successfully removed card position counts as 0.

What happens on your turn

A replaced table card leaves your hand and becomes the match card. If you discard the card you just drew, that drawn card becomes the match card instead.

Match and remove a card

When a match card appears, a player who knows they have a card of the same rank may try to remove it. You can select only a card you have previously seen. A correct match removes that card from your layout, and its position counts as zero for the rest of the round.

Memory matters: selecting the wrong position wastes the opportunity and may carry an in-game consequence shown by the interface. Watch cards revealed by power moves and remember cards that have been exchanged.

Power cards

Power effects are optional and apply when the relevant drawn card is discarded rather than kept. The game presents the available choice when a power can be used.

• 7 or 8: privately look at one of your own hidden cards.
• 9 or 10: privately look at one hidden card belonging to another player.
• Jack or Queen: exchange one of your cards with another player’s card without looking at the target card first.
• King: look at another player’s card and then choose whether to exchange it with one of your own.

Power cards create information as well as movement. A card you understood earlier may no longer be in the same position after an exchange.

Calling Koops

The Koops action becomes available when your current known total meets the limit shown by the game, normally 5 or less. Call Koops when you believe your hand can win.

After you call, your cards freeze. Every other active player receives one final turn. The round then ends, all remaining cards are revealed, and totals are compared. Calling Koops does not guarantee victory: another player may already be lower or may improve during the final turns.

Winning, scoring and coins

• The player or players with the lowest final card total win according to the result shown by the game.
• The round pot is funded by the displayed entry fee and paid out by the game result.
• New profiles currently begin with 500 virtual coins.
• A qualifying score that is a multiple of 25 may receive the bonus displayed by the game.
• You may spend the displayed amount to check your current hidden value when that feature is available.

Coins are virtual gameplay items with no cash value. Optional rewarded-ad offers may provide coins after a completed ad, subject to availability, consent, security checks, cooldowns, and daily limits.

Ways to play

Computer mode

Create a game with computer opponents for a quick practice round. Bots follow the same basic turn structure as human players.

Invite friends

Create a private room and share its five-digit room code. Friends enter the code and a player name to join the same lobby. Treat active room codes as temporary invitations.

Online play

Join available online players through the matchmaking option. Connection interruptions may require reloading or rejoining. Keep display names appropriate for a general audience.

Auto-play

The host can enable Auto-Play in Settings. By default, the game makes a safe move after 60 seconds of inactivity, up to 5 times per player in a round.

Quick strategy tips

• Use your opening peek on positions you can remember reliably.
• Replacing a known high card is usually safer than replacing an unknown card.
• Track exchanges: information becomes outdated when cards move.
• A power card can be more valuable for information than for its printed number.
• Before calling Koops, consider what each opponent can still change on their final turn.
