Editing Upwords (section)

== Gameplay ==
To determine play sequence, each player draws a tile; the player with the letter nearest to A will be the first to play. The tiles are returned to the draw pile.

Each player draws seven tiles to start the game. The first player forms a word with one or more of their tiles, and must place it so that the tiles cover one or more of the four central squares. The player then draws more tiles to replace those played. Play continues clockwise.

Subsequent players may put tiles on the board adjacent to and/or on top of the tiles already played, as long as all words formed are found in the dictionary being used and the rules below are followed. All words must read horizontally from left to right, or vertically from top to bottom.

All tiles played on a turn must form part of one continuous straight line of tiles across or down.

For example, if the word CATER is on the board, a player could put a B and E in front of CATER and then put an L on top of the C and a D on top of the R to build BELATED. 

Restrictions on words are as follows:

* No [[proper noun]]s
* No hyphenated words
* No words requiring an apostrophe
* No abbreviations or symbols
* No prefixes or suffixes which cannot stand alone
* No foreign words unless they are in the dictionary
* The 2008 edition included a new rule: Players may not pluralize a word simply by adding an S at its end. However, such a play is allowed if the S is part of another complete word that is played onto the board in the same turn. This rule is intended to prevent players from capitalizing on one another's words without changing them or playing new ones.

Restrictions on stacking tiles are as follows:

* No stack may be more than five tiles high
* No tile may be stacked directly onto a duplicate of itself
* At least one tile or stack must be left unchanged; a player may not cover every letter in a word on a single turn.

A player may choose to pass at any time, or discard one tile and draw a replacement instead of playing. Once the draw pile is exhausted, the game ends when any player runs out of tiles, or every player passes in a single round. In some versions of the game it doesn't end when a player runs out of tiles, only when all pass or all the tiles are played.
