Hello:

My Friend Konner from Austria has Gave Me a cool Game

It's called Konigrufen

Here are The rules

Players and Cards
There're four players and The Game is dealt, bid and played clockwise.
A French- or German-suited 24-Card pack is used. The Cards in each suit normally rank from High to Low A-K-Q-J-10-9 or A-K-O-U-10-9, but there are some bids in which The Ten ranks between The Ace and The King.
The Deal and Bidding
Any player may deal first, and thereafter the turn to deal passes clockwise. The dealer shuffles and The player to dealer's right cuts. The dealer then deals out All of The Cards in packets of Three, so that each player has Six Cards.
The player to dealer's left begins The bidding. There are Nine possible bids, listed with Their objectives and scores in The Contracts section below. Each player in clockwise order must either pass ( saying "Gut") or bid higher than The previous bidder (Bettler is an exception - see below). If All Four players pass, The Special contract Schurln is played, to punish The player who passed with The best Hand. If someone bids, The bidding continues for as many circuits as necessary until Three players have passed. A player who has passed can't bid at a subsequent turn.
Play and Scoring - General Rules
The highest bidder leads to The first trick. Players must follow suit to The led Card if Possible, and when following suit must if possible beat The highest Card of that suit so far played to The trick. A player Who can't follow suit may play any Card. The trick is won by The highest Card of The suit led. The winner of each trick leads to The next.
Usually The players settle up in chips after each Hand, and The payments are given in chips. If No chip is available, the game is played for Tokens. When Two players play against Two, one loser pays one winner and the other pays the other. When one player plays alone against three, The lone player pays or receives The appropriate amount to or from each Opponent. In Bettler and Schurln, there are other possible situations, which will be described under those contracts.
The Contracts
The possible bids, in ascending order, are as follows.

1. Bettler
The bidder undertakes to lose every trick, playing alone. The King is The Second highest Card. It's bid by placing The Card One intends to lead to The first trick face down on The Table. If Bettler has been bid and No One has bid higher, it's possible for another player also to bid Bettler rather than passing. The Mitbettler (The second Bettler) also lays down a Card to be played to The first trick. As soon as Someone makes a higher bid, The Bettlers're cancelled and The players must take Their Cards back. If No One bids higher, The first player who bid Bettler leads to The first trick, and in this first trick and The Mitbettler must play The card that He or She put face down: The requirement to follow suit doesn't apply to this Card. It may be possible to get rid of an Ace this Way, discarding it on a lead of a different suit, but if unluckily The first Bettler player leads The suit of The Ace You put face down, You'll have top play it and Your contract fails. The score for Bettler played by One player is 30 chips. If there's a Mitbettler The payment is increased to 50 Chips and The players settle up as follows.
• If both Bettlers succeed, each of The other Two players pays 50 Chips and each Bettler receives 50 Chips.
• If One Bettler succeeds and The other loses, the winner pays 150 chips to The loser, and The other Two neither pay nor receive anything.
• If both Bettlers lose, They each pay 100 Chips and each of The other Two players receives 100 Chips.

2. Durchmarsch mit einer anderen
The bidder undertakes to win every trick with The help of a His or Her Team Member. Before leading to The first trick, The bidder names a Card whose holder will be The bidder's Team Member. This player mustn't announce who They're, and will become known only in The course of play. The King is The Second highest Card unless The bidder calls a Ten, in which case All suits rank with The Ten Second highest, between Ace and King. The score for this contract is 40 Chips.

3. Durchmarsch am letzten
The King is The Second highest Card, and The bidder undertakes to win The first five tricks. Whoever wins The sixth trick will then be The bidder's Team Member and They win 40 Chips. If The bidder wins The Sixth trick, All Three of The other players pay The bidder 40 Chips. If The bidder loses any of The first Five tricks, The bidder loses alone and has to pay 40 Chips to each of The other Three players.

4. Plauderer
The bidder must lose every trick, playing alone. The King is The Second highest Card. As in a Bettler, The bidder places The Card to be led to The first trick face down on The Table. If No higher bid intervenes, it's possible for another player also to bid Plauderer. This's known as mitplaudern. The Mitplauderer also places a Card face down, which'll be played to The first trick if The Plauderers are played: The requirement to follow suit doesn't apply to this Card. After The first trick, The Opponents of The Plauderer place All Their Cards face up on The Table and can discuss How to play. If there's also a Mitplauderer, only The Two players who'ven't bid Plauderer expose Their Hands and can discuss The play. The player of a Plauderer wins 50 Chips from each Opponent, or pays them each 50 Chips. If there're Two Plauderers The payment is 100 Chips and is settled in a similar way to Bettler. If both Plauderers win, each receives 100 from One of The other players; if just One wins the winner is paid 300 by The loser and The other Two players pay nothing; and if both lose They each pay 200 and each of Their Opponents collects 200.

5. Durchmarsch Hundert mit einer anderen
The bidder, who must hold The King and Queen (Over) of some suit, undertakes to win every trick with The help of a Team member. Before leading to The first trick, The bidder names a Card whose holder'll be The bidder's Team member, hidden until The called Card is played. The Ten is always The second highest card of each suit, no matter What card's called. Score: 60 Chips .

6. Durchmarsch Hundert am letzten
The bidder, who must hold The King and Queen (Over) of some suit, undertakes to win The first five tricks. The Ten is the Second highest Card of each suit. Whoever wins The sixth trick will then be The bidder's Team Member and They win 60 Chips. If The bidder wins The sixth trick, all Three of The other players pay The bidder 60 Chips. If The bidder loses any of The first five tricks, The bidder loses alone and has to pay 60 Chips to each of The other three players.

7. Zehnermord
The bidder undertakes to win all six tricks, playing alone. The Ten is the Second highest Card of each suit. Score: 60 Chips.

8. Königmord
The bidder undertakes to win all Six tricks, playing alone. The King is The Second highest Card of each suit. Score: 70 Chips.

9. Hundertermord
The bidder, who must hold The King and Queen (Over) of some suit, undertakes to win all six tricks, playing alone. The Ten is the second highest card of each suit. This's The highest contract, scoring 80 Chips.
Special contract: Schurln
This contract can't be bid. It's played only if All Four players pass. The player to dealer's left leads to The first trick and The Ten is The second highest Card of each suit. The aim is to avoid winning Aces and Tens in tricks and to avoid winning The last trick. When All Six Tricks have been played The players count The value of Cards in The tricks They've won, counting 10 Card points for each Ace or Ten. The winner of The last trick gets an extra 10 Card points, so The total for all four players will be 90 Card points. The player with most Card points pays 10 Chips to each of The other players. If Two players tie for most Card points, each pays 10 Chips and The others win 10 Chips, and if Three players tie (with 30 Card points each), They each pay 10 Chips to the player who has none.
