Gutenberg's Sub icon Gutenberg's Sub: Quick Intro

You form new words by substituting one (and only one) letter already on the board; you may add additional letters.

Click your mouse's left button when positioned over a tile to pick it up; the cursor will change to the letter on the tile. Click your mouse's left button when positioned over a blank square to drop a tile; the cursor will change to the default arrow cursor.

You do NOT have to hold the left mouse button down to drag a tile: just click to pick a tile up and click to put a tile down.

The letter pool is composed of 100 tiles -- 98 tiles with letters and 2 blank tiles which are "wild" and can be used as any letter. Tiles are randomly drawn from the pool to fill the trays at the beginning of a game and to refill the trays after each play.

You use the letters in your tray to form horizontal and vertical words crossword-fashion on a 15 x 15 board.

The first word must consist of two or more tiles placed across the center square horizontally or vertically.


After the first word is checked, you substitute one new tile for a tile already on the board when forming a new word. You must substitute one and only one letter.

For example, if PEG were on the board you could replace the first letter to form BEG or the second letter to form PIG or the third letter to form PEA. The letter on the board that is replaced disappears from the game.

You can place additional letters on the board to extend the new word or form a crossword as long as you also replace one letter in the word. For example, if PEG were on the board you could substitute B for the P and add S to form BEGS. Or you could form SPEND substituting N for the G and adding S and D.

You may replace a letter on the board with the same letter. So, if PEG were on the board you could form PEGGED by substituting a P for the P, or E for the E or G for the G and then adding GED.

All new letters will be in the same row or column as the substitute or they will be perpendicular to the new word formed by the substitute. For example, if PEG is on the board you could replace the T and add A above it and E below it to form the new word PET and the crossword ATE.


When a valid word is checked, the score for the word is the sum of (1) the letter-points of the primary word and all new cross-words, (2) the length of the primary word and new cross-words and (3) any bonus points.

When you use all seven tiles in your tray to form a word (sometimes called a bingo), the total points for the play are doubled.

After you form a word, if you choose the menu item "Help | Calculate Word's Points" the points for the play will be calculated for you.

At the end of the game penalty points equal to the letter-points of the tiles in each player's tray are subtracted from each player's score (if at least one scoring move has been made).

The player with the highest score at the end of a game is the winner.
