Rules: - Grab 25 cards laid out on the field. - Three specific characteristics of a chemical structure will be read aloud to identify the card. - You can take a card even while a hint is being read. - Making 3 or more mistakes results in a game over. - You may continue to try for the correct card even after making a mistake. Target Users: - Students: Ideal for previewing or reviewing chemistry and pharmacology coursework. - Teachers: Can be utilized as a teaching tool or integrated into classroom activities. - Chemistry Enthusiasts: Perfect for anyone looking to deepen their chemical knowledge. Request for Users: Upon launching the app for the first time, we kindly ask for your cooperation in completing a brief survey (4 questions, approximately 1 minute). Note: Survey results may be used for academic research papers. Message: This "Structure Karuta" began as a project to help everyone—whether they excel at organic chemistry or struggle with it—enjoy the learning process. During development, we received valuable advice from Professor Seiji Esaki of the School of Pharmacy at Osaka Ohtani University. This app is part of an educational research project and is supported by JSPS KAKENHI Grant Number 23K02725. I hope that through this app, many people will become familiar with chemical structures and find a bridge to further learning.
