Setup

Players decide which board size will be used: small (5x5), medium (7x7) or large (9x9).

The starting word with the length equal to the board size is chosen randomly and each letter is written into every cell of the middle row.

Game Play

The player on turn takes the following actions:

1. Place a new letter

The player chooses an empty cell and places any letter there. The chosen cell must be horizontally or vertically (also diagonally if option "allow diagonal connections" is chosen when creating the game) adjacent to another cell containing letter.

2. Form a word and score points

The player starts with any letter on the board and then keeps joining horizontally or vertically (also diagonally if option "allow diagonal connections" is chosen when creating the game) adjacent letters until a desired word is formed. The player scores points equeal to the length of the new word.

For example:

Left image shows the situation before the first move. New letters can be placed into the green cells only. The first player places a new letter "T" and forms the word "TEA". The player scores 3 points.

The following rules must be met when forming the new word:

A) The new letter placed in step 1 must be used in the new word.

B) The letter of the board can be used only once. (No loops)

C) The new word must be not scored in the previous rounds or if there was identical word scored previously, then the new word should not share any letters with the old word. The starting word (see Setup) is considered scored, but no player receives points for it.

D) The new word must be from the list of possible words (see below).

In order to prevent the game from falling into a state where no legal word can be formed it is always allowed to score any newly placed single letter as a word (and gain 1 point).

Nouns should be entered without an article. As letters entered are capitalized, the word check is case insensitive. E.g. Entering the word "BAUEN" would match the words "Bauen" (noun) and "bauen" (verb). All nouns are in the singular nominative case. Proper nouns (person names, location names, etc), were removed from the list of possible words. Abbreviations also were removed. Only infinitive form of verbs is used. A hyphen ("-") is omitted when compiling the words, so "e-mail" should be entered as "email".
