Rules
Opening move
The first word must cover the centre star and use at least two tiles.
Connecting
Every later play must touch at least one tile already on the board.
One line
All tiles you place in a turn go in a single row or column with no gaps.
Premium squares
Letter and word bonuses count only on the turn they are first covered, and word multipliers apply to every word formed on that turn.
Cross-words
Every new word formed, including perpendicular ones, is scored.
Blanks
A blank can be any letter but always scores zero.
Bingo
Using all seven rack tiles in one turn adds 50 points.
Exchange
You may swap any number of tiles when at least seven remain in the bag. It costs your turn.
Ending
The game ends when the bag is empty and one player uses their last tile, or after six consecutive scoreless turns.
Final scoring
Each player loses the value of their unplayed tiles; the player who went out gains the total of everyone else's.
