Idea of the game and goal
The players are playing cards from their hands and thereby occupy numbered fields on the board. A player wins as soon as he owns four fields in a row (horizontally, vertically or diagonally). But a player owns a field only if he has the majority of stones on that field. If no player wins within 20 rounds, the player with the most valuable fields wins.
Examples:


Those are three correct winning situations. 
No winning situations: The fields are neighbouring but not in a row. 
Note that the pictures show fields where each player has a majority of two stones on each field (the stone is in the center in that case). It would also be enough if each player had only a majority of one stone!

Game preparation
 The board consists of 36 numbered fields.
 Each player gets his stones.
 The game cards are shuffled and each player gets 4 cards, which he takes into his hand. The remaining cards are placed beside the board as talon.
Playing the game
The player on turn may play one or more of his cards to place a stone on the field which has a number equivalent to the sum of the values of the played cards. He then draws cards until he again has four cards in hand.
1. Playing one or more cards
 The player has to play at least 1 card, but may also play up to four cards.
 If more than one card is played, the sum of the cards is calculated to determine the field where to place the stone.
2. Placing a stone
Each player places exactly one stone during his turn.
Example: Player yellow plays the cards 5, 11, and 13. He places then a stone onto the field 29 (= 5 + 11 + 13).
3. Drawing cards
 After a player placed a stone he draws as many cards as he played.
Additional rules
 You may not place a stone onto a field where the opponent already has a majority of two stones.
Example:
Player Yellow already placed two stones on field 12, Red has only one. Player Pink would like to place one there but may not do so, since Yellow has a majority of two relative to Pink. Only Red and Yellow may put stones there. 

 If a player has two more stones than any other player on one field, the field is locked, nobody may place stones there anymore.
No possible move
In the rare case that a player cannot perform any valid move during his turn he exchanges his cards for four new cards but may not do anything else during his turn.
End of game
The game ends if a player has a majority in four fields in a row. Majority means that the player has at least one more stone than anybody else in the fields. If nobody else has a stone in a field, one stone is enough to have a majority.
If no player is able to win after 20 rounds, the player with the most points wins. In this case, each player gets the numbers of the fields where he has a majority as points. If two players have the same number of points, the player who owns the field with the higher number wins.
Example 1: Player Yellow has three stones on field 23; Red and White have two stones. Yellow gets 23 points for this field.
Example 2: Both players Red and White have two stones on field 7. Nobody has a majority, nobody gets points for field 7.
