Patterns must only connect to one other tile already on the board. Existing patterns CAN NOT be extended. You score all the tiles in your pattern, including the tile already on the board. Any pattern will do as long as there is one single rule that governs the pattern and the rule is used at least twice. Rules are only accepted if validated by the computer rule program.
Players can pass, refreshing their tiles but their turn is forfeited.
Tiles must be played in a straight, horizontal or vertical line. Place your mouse on the green score bar to view scores. To manually check your score, simply find the sum of the digits and multiply by the number of tiles in the pattern. This is purposely done in order to ensure a level playing field for all players regardless of ability. Your pattern will be validated after the rule is entered into the window at the top of the vault and then the enter key or the GO button is clicked.
