"Cruce" is a game similar to Whist. The game has the following elements:

The deck

The card deck consists of 24 different cards:

4 suits whose names vary with the region you are playing. I know them as Bell, Leaf (or green), Acorn and Heart (or red). For now, none of this colors is superior to another.
Well Known Deck representation: Clubs for Bell, Spades for (Green) Leaf, Diamonds for Acorn, Hearts remains unchanged.
6 values of each suit: II, III, IV, IX, X and A (ace).

The game board

The number of players in a game is not fixed. It can be carried with 2, 3 or 4 players. In the first 2 cases, the game is an individual one (we will say that the players form one member teams) while in the last case, it will be played in 2 teams of 2 players (the opposite positioned players will form a team).

The game

A game consists of more rounds and it ends when one of the teams reaches a certain score. The score's value is fixed at the start of the game, being usually 11, 15 or 21. To end a game, it is necessary that there must be a gap of 2 game points between the player who crossed the point limit and opponent. Otherwise, the game will continue until this constraint is fulfilled.

The round

A round has the following stages:

Cards distrubtion will take place by dealer.
1. In a game with 4 players (it will be called game of four), every player will get 6 cards.
2. In a game with 3 players, every player will get 8 cards.
3. In a game with 2 players, every player will get 8 cards and 8 cards remain on the table (Cards face down).
Every player, counting clockwise from the first who recived the cards, will place a bid. The dealer should be the last to place the bid. The bidding process will be described later.
After the bidding ends, the game starts. The winner of the bidding is the one who chooses the trump and will deal the first card (it must be a trump).
The winner of a round is the one who starts the next round, by placing a card on the table.
When the players have no more cards (note that all the players will always have the same number of cards), each player's score is computed.
The game proceeds to the next round, until the ending constraints are fulfilled.

The bidding

Every player says "how many bid points" he thinks will make (this is called a bid). The one who has the largest bid wins the bidding. Now, let's what means to make one, two etc. For every "one" it is necessary to gain 33 points. So, to make one you will need 33 points, to make two - 66 points, three - 99, four - 132, five - 165, six - 198(I doubt you will ever make 6). If the team which won the bidding does not gain enough points compared to its bid, the points will be subtracted from its score. Let's see an example: We are playing a game of four, and the score is 6 - 8. The bidding is won by a player of the first team, who said two. At the end of the round, the first team gains only 64 card points and the second one, the rest of 56 card points. The score after this round will be 4 - 9. The game goes on and the first team wins the bidding with two. If at the end of the round the first team has 102 card points and the second one 18 card points, the score will be 7 - 9. Note the difference from whist, where if you do not fulfill the bid, your score decreases. Also, here is only one bet for every round. It is possible not to bid (or to bid 0).

The points

II is worth 2 card points
III, 3 card points
IV, 4 card points
IX, 0 card points
X, 10 card points
ACE, 11 card points
Bid points - Chosen by player at the start of every round
Score points - Tells the current score point of player, (Game Points - Score Points) tells how much more Score points are required to win the game.
Game points - Chosen by player to win the game

There are also some card combinations that may bring bonus points. If a player has in hand a III and a IV of the same suit, they form a call. This is worth 20 or 40 card points, if the suit is trump. To make a call, it is necessary that the player who owns it to be the first in that round and to put on the table one of the two elements (the III or the IV).

The hand

The game of two will be treated separately. Now, the game of 3 and 4 will be described. When a player puts a card of value V and suit S, all other players must put cards of same suit. If a player does not have a card of suit S, it must put a trump. If he has not any trump either, he can put whatever he likes. Also, a player must put a card with a value V' > V, if he has one. Otherwise, he can put anything. If a trump was played, the rules are a little bit more complicated.

Let's suppose I am the third player. The first player has put a bell of IV (the trump is leaf). I have in hand the ace and II of bell. Normally, I should put the ace, but the second player has no bell and he must put a leaf (the trump). He puts the III of leaf. Now, the value rule for bells stops and I can put the II of bell. If the fourth player has a IV of leaf and a II of bell, he must place the IV of leaf.

Another formulation of the value rule is: at every moment, a player must put a card that will win the round, if possible.

Who wins the round?

If the trump was not played, the round is won by the player who put the card with the highest value and the suit of the first card. If the trump was played, the round is won by the player who put the trump with the higest value. The player who wins the round will start the next one.

The game of two

In a game of two there is no value or color rule as long as there are cards facing down on the table. Also, after putting a card, each player will take another on from the table, while possible.

Now, it is time for a resume: In a game of "cross" will be played as many rounds as necessary for a team to win. In every round, each player gets a number of cards, depending on the number of players. After all players saw their cards, a bidding takes place, which is won by the player who bids the most. The winner chooses the trump and starts the first round. There will be a fixed number of hands, equal with the number of cards each player gets. At the end of all hands, the points are counted and the score is updated.
