Flash Stacks is a Chrome extension designed specifically for magicians who utilize memorized decks in their performances. This tool employs flash card-style memory techniques to help users learn and refresh their memorized card stacks effectively. By simply clicking on the extension, a pop-up displays either the face of a card or a number, allowing users to test their memory by guessing the corresponding side before revealing the answer.

In addition to its core functionality, Flash Stacks includes a Settings panel that enables users to customize the order of their card decks and the format of the questions and answers. This flexibility enhances the learning experience, making it easier for users to tailor the tool to their specific memorization needs and preferences.
