Cells and premium squares

A board is a square grid of cells. Most are plain; the rest are premium squares, which change what a play scores. There are 18 kinds of premium square.

• Plain cell: scores a tile at face value.

Classic squares

The four classic squares can appear on every board.

• 2L Double letter: Doubles the tile placed here.
• 2W Double word: Doubles every word through it.
• 3L Triple letter: Triples the tile placed here.
• 3W Triple word: Triples every word through it.

Exotic squares

Each board offers only a few exotic types: 2 on easy, 3 on medium, 4 on hard, 5 on brutal.

• ⌇ Bridge: Plus 80 if the play connects two different words already on the board.
• ⧉ Clone: Copies the tile played here back into your rack.
• ❄ Cold: Dead unless used on your last play, where it triples the word.
• 2C Cross: Doubles the crossing word only, never the main one.
• ↑ Escalator: Doubles a word on your first play, triples on your second, quadruples after.
• 5+ Gate: Triples the word, but only if it is five letters or longer.
• LO Humble: Plus 40 for a tile worth 6 or less.
• KEY Keystone: Plus 60 if the word uses two or more tiles already on the board.
• ≡ Match: Doubles the tile if that same letter appears elsewhere in the play.
• ⇄ Mirror: Plus 160 if the word also reads as a word backwards.
• HI Rich: Plus 40 for a tile worth 14 or more.
• ½ Toll: Halves every word running through it.
• ∅ Void: Any tile here scores nothing.
• Æ Vowel bonus: Plus 32 if the tile is a vowel.

Weights

Each square's page gives its weights. Placement weight is how often the square is drawn for a cell once a board can carry it; selection weight is how often an exotic type is chosen for a board at all. Both are relative to the other squares.
