Word Zero is a crossword board game in the style of others you may have seen. Two players take turns placing tiles on a board to form words. Tiles have different point values, and some board spaces have bonuses (like double-word score), and so on. What makes this game different is the absence of ... annoyances. - Zero interruptions: We have no ads during game play. - Zero distractions: We don't have gems, rewards, stickers, or achievements. - Zero deception: We do offer computer players (Bots), but they never pretend to be real people. - Zero manipulation: We don't send you notifications nagging you to play a game. - Zero cheats: We don't have in-game assistance or power-ups. Instead, Word Zero has a simple model of requiring one "token" for each game you play. - Each new user gets a batch of free game tokens to start. More free tokens are provided periodically and as resources allow. - Users who want to play more often can purchase additional tokens through In-App Purchases. - Game tokens do not expire and can be used at whatever pace you like. Highlights: - Sign In With Apple - Games are "correspondence" style. Each player has up to 3 days for their turn, but it is considered good form to play as quickly as possible. If a player does not make a turn within that time period, a pass is automatically assumed and it becomes the other player's turn. If a player "auto-passes" twice in a row, and if their opponent makes a turn in between, the game is declared a forfeit and the opponent wins. Note that it is considered bad form to abandon a game. - Languages currently supported for game play include English and Spanish - For games in English, we use the NASPA Word List, which is the official word reference for SCRABBLE play in the United States and Canada. - Push notifications to let you know when it is your turn - Players who use this app are expected to play without outside assistance. Using dictionaries, word lists, or other helps during a game is considered cheating. All players are on the honor system. - An Elo rating system is used to give an approximate indication of the strength of each player. - Although the primary focus of Word Zero is to facilitate games between people, the ability to play against computer players ("Bots") is provided as well. The Bot-related features are intentionally kept separated from other areas of the app, so there can be no confusion about whether you are playing a Bot or a real person.
