Series Mattis Rules / How to Play

Quick start: Serie Mattis has two phases. First you collect cards by winning tricks and underkjemping battles. Then the cards you won become your hand, and you try to shed them by playing legal singles or same-suit series.
1. Goal of the game
Win the collection phase in a useful way, then be one of the first players to empty your Phase 2 hand. The last player stuck with cards loses the round.
2. Phase 1: Collection
  • Everyone starts with 3 cards.
  • Play one card, then draw back up if the stock has cards.
  • You may blind-play from the stock, except the final hidden trump card.
  • Highest value wins the trick. Ace is high.
  • The winner takes the trick cards into their Phase 2 stock.
3. Underkjemping / battle
  • If equal values appear in a collection trick, the lowest duplicated value triggers underkjemping after everyone has played.
  • Only the tied players battle.
  • If battle cards tie again, those battle cards stay on the table and a new battle round starts.
  • If nobody can continue, players take their own cards back into their Phase 2 stock.
4. Phase 2: Shedding
  • The cards you won in Phase 1 become your Phase 2 hand.
  • The hidden final card reveals trump and joins the hand of the player who drew it.
  • Play singles or same-suit ascending series.
  • You must beat the active suit, or use trump if the active suit is not already trump.
  • You may take the first unresolved set instead of playing.
  • First player to empty their hand ranks first; last player with cards loses.

Gurka Rules / How to Play

Quick start: Gurka is about avoiding the dangerous final trick. Everyone gets 6 cards. Suits do not matter; only rank matters. You must beat or match the current highest card if you can, otherwise you dump your lowest card.
1. Goal of the game
Stay alive by avoiding points from the last trick. The last player not eliminated wins the match.
2. Players and cards
  • Gurka supports 2–8 players.
  • Each active player receives 6 cards each round.
  • Suits do not matter in Gurka.
  • Ranks are 2 low up to Ace high. J = 11, Q = 12, K = 13, A = 14.
3. Playing a trick
  • The leader plays any card.
  • After that, you must play equal to or higher than the current highest rank if you can.
  • If you cannot beat or match the current highest rank, you must play the lowest card in your hand.
  • The highest card wins the trick. If several players tie for highest, the last highest card wins.
  • The trick winner leads the next trick.
4. Scoring and elimination
  • Only the final trick of the round scores.
  • Every player who played the highest rank in that final trick takes that many points.
  • At the score limit the first time, you are warned and reset to the highest safe score among the other players.
  • At the score limit a second time, you are eliminated.
  • The game continues until only one player remains.

Rules / How to Play

Quick start: Amerikaner is a 4-player trick-taking card game. Bid how many tricks your side can win, take the kitty if you win the bid, choose trump by leading the first card, call a partner card, then try to make your contract. The kitty counts as 1 trick for the bidder's side.
1. Goal of the game
Win points over several rounds. A full match ends when a player reaches the winning score from Settings. You can also play a single round from the menu.
2. Players, cards, and the kitty
  • The game has 4 seats: You, Left, Top, and Right.
  • A standard 52-card deck is used.
  • Each player receives 12 cards.
  • The remaining 4 cards are the kitty.
  • The bid winner takes the kitty, then discards exactly 4 cards.
3. Bidding
  • Players bid in turn or pass.
  • A number bid means your side promises to take at least that many tricks.
  • The minimum bid can be changed in Settings.
  • In this version, number bids go up to 13. Bid 13 means taking every trick with a partner; Amerikaner is the special solo all-tricks bid.
  • When everyone else has passed, the highest bidder wins the kitty.
4. Trump and partner call
  • After discarding, the bidder leads the first card.
  • The suit of that first card becomes trump.
  • Then the bidder calls one trump card they do not have.
  • The player holding that card becomes the bidder's partner.
  • If no live callable trump card exists, the bidder plays alone.
  • The partner may be hidden until the called card is revealed through play.
5. Playing tricks
  • The leader plays one card.
  • Other players must follow the led suit if they can.
  • If they cannot follow suit, they may play any card.
  • Trump beats non-trump.
  • If no trump is played, the highest card of the led suit wins.
  • The trick winner leads the next trick.
6. Scoring in this game
  • The kitty always counts as 1 trick for the bidder's side.
  • For normal bids, the bidder's side succeeds if kitty trick + played tricks is at least the bid.
  • If the bidder's side succeeds, each bidder-side player gets points equal to the bid.
  • If the bidder's side fails, each bidder-side player loses points equal to the bid.
  • Defenders score 1 point for each trick they personally win.
  • Bid 13 means the bidder side must take the kitty trick plus all 12 played tricks, with a partner.
  • Amerikaner means the bidder plays alone and must win all 12 played tricks.
  • Successful Amerikaner gives +52 to the bidder. Failed Amerikaner gives -52 to the bidder.
7. Online multiplayer notes
  • The host browser runs the game logic and bots.
  • Other players join the room and take open seats.
  • Empty seats stay as bots when the host starts.
  • If the host leaves, the room closes.
  • This is intended for casual play with people you trust.

Scoring
  • Most cards: 1
  • Most spades: 1
  • Each Ace: 1
  • 10♦: 2
  • 2♠: 1
  • Last take: 1, and also collects remaining table cards after the final capture.
  • Clear table: shown as clears during the game, then scored as net clears at the end.
Builds
  • Builds show every card inside the build, but never show a build value.
  • You may only create a build when the rules can prove you hold a card that can later take it.
  • If you own a build, you may add another group to it only if the original hidden target stays possible. You may not change your own build target.
  • The opponent may rebuild your build freely, as long as all cards from the build are included and they hold a card that can take the new build.
  • If you own a build, you cannot simply trail a loose card; you must capture something or create/build again.
  • A, 2♠, and 10♦ have special hand values: A=14, 2♠=15, 10♦=16. On the table they count normally: A=1, 2♠=2, 10♦=10.
