BotWR, developed by The Azure Flame, is an item randomizer app for the game Breath of the Wild (BotW). The app offers randomization algorithms and users can set their own rules to play the game. The game begins after obtaining the paraglider from the Great Plateau, and the player is not allowed to have any items or equipment in their inventory at the start of the game.

To unlock item types, players need to complete shrines and enter their names into the app. Korok seeds, Towers, and Divine Beasts can also be completed to unlock useful hints for the location of certain items. Players can collect their newly found items to unlock even more, until they can beat the game by defeating the final boss, Beast Ganon.
