Shendoku is a true multi player game based on the Sudoku puzzle

Shendoku is a game developed in 2006 by DR Shenton and involves taking two completed SuDoku grids, or solution grids, and making two blank grids of identical layout.

Each player takes a completed grid and a blank grid and begins by adding grid references, 1-9 and A-I on each grid in an identical fashion. Each player should not see the others grid.

Game play involves requesting the content of a square in the grid from ones opponent. This can initially be quite fast, until the minimum number of squares is achieved for further solving the grid using SuDoku rules. At this point the game play becomes more involved.

Each player will try to attempt to resolve their grid first, the winner being the first to complete their grid, correctly, and shouting "SHENDOKU". The game becomes a war of nerves as each player resolves more squares.

To make the game more challenging, optional rules include the use of timing (setting limits between asking fo squares) or allowing any player to refuse to answer a request while they are able to continue filling squares themselves.

When more than two players wish to participate, the only difference is that the direction of play should be decided upon and each player requests a square from the next person in the direction of play, while the one on their opposite side will eventually ask the question of them.

Where a group challenge is required, try using one defended grid, as it is termed, and multiple players with blank grids who ask for a square in turn in order to resolve their grid first. As all grids will be identical, there is more devious play to be had, with players asking for squares that will do little to help their opponents, while resolving squares themselves to gain an advantage.

The game is already available in book form and can easily be drawn or adapted from SuDoku books, newspapers etc.

Shendoku is a trademark and the game format is copyright, so you can only make this for play yourselves, not to sell or distribute.
