SUDOKU CHALLENGE AMONG FRIENDS AND RELATIVES

GENERAL RULES:

• 2 to 5 players.
• Play on a 9x9 sudoku grid (81 spaces).
• Each space must contain a number from 1 to 9.
• All the numbers from 1 to 9 must be present in each column, each line and each 3x3 block.
• Numbers can not repeat in a same column, line or 3x3 block.
• The objective of the game is to obtain the highest score at the end of the final round.

CHALLENGE OPTION:

• Regular challenge (by default) : How many numbers each player enters in a round follows the sequence 1, 2, 3, 1, 2, 3…
• Shortened challenge : How many numbers each player enters in a round follows the sequence 1, 2, 3, 3, 3, 3…
• Express challenge : How many numbers each player enters in a round follows the sequence 3, 3, 3, 3, 3, 3…

HANDICAP OPTION:

• With handicap (by default): Players #2 to #5 get respectively a +4, +6, +8 and +10 handicap in the first round.
• No handicap: Players have no handicap.

CHRONO OPTION:

• No chrono (by default) : No time limit to respect.
• With chrono : A time limit is determined. Only the numbers entered within that time limit will count.

TWO AGAINST TWO OPTION:

• It is possible to form two teams of two if four players take part in the challenge. The two players from the same team must not play one after the other. The winning team is the one with the most points.

FINAL ROUND OPTION:

  Final round (definition): Round at the end of which it is anticipated the sudoku grid will be completed.

• Increasing (by default): The order of play is determined by the score, from the lowest to the highest.
• Status quo: The initial order of play is maintained.
• In the event of a tie, the initial order of play is maintained among those players showing an identical score.

ORDER OF PLAY AND OPTIONS:

• The order of play and options are determined at the very start.

ENTRIES:

• Each player enters his numbers in the sudoku grid then counts his points.
• Always verify the numbers and the score of the previous player before playing one’s own round.
• Any player can ask for an explanation if he doubts the validity of another player's entry.
• If in error, a player must correct its entry. That entry even once corrected does not score points.

SCORE:

• A number entered in the sudoku grid is worth its nominal value in points.
• 10 points if a player completes a column, a line or a 3x3 block (maximum 10 points per round).
• 10 points if a player does not participate in the final round.

BASIC STRATEGIES:

• Try entering the bigger numbers first while also attempting to complete a column, a line or a 3x3 block.
• Prevent if possible the next player from completing a column, a line or a 3x3 block.
