Welcome to Sumo Card.


What is it?

Sumo card is an interactive Japanese vocabulary learning environment which aims to promote vocabulary learning in conjunction with widely available content such as readings, songs and short stories.

How does it work?

You can either create your own or use others vocabulary lists which will be used to quiz on the words in that list. They are added into a vocabulary pool that you are subsequently quizzed on. it is prefered that the packages to be based around a short story, news article, song or video that is freely available.

What are the specifics?

You add a list of words to your current pool and the word begins with a rank of 十両 じゅうりょうwhich in sumo is the rank below the Rank and File 前頭 まえがしら. We use this rank to begin in Sumo Card for the sake of simplicity. Similar to real sumo, there are specific promotion criteria detailed below. These criteria are not exactly the same as real sumo for simplicities sake.

Rank Base Time between questions Question Type Promotion Criteria
十両 18 Hours Single Choice Get >= 5 questions correct per run
前頭 48 hours Multiple Choice Get >= 5 questions correct per run
小結 3 days Free Response Get >= 5 questions correct per run
関脇 7 days Free Response Get >= 5 questions in two successive runs
大関 14 days Free Response Get >= 7 questions in two successive runs
横綱 28 days Free Response No Promotion Available

There is also a buffer time which is randomly created and added to the base time to attempt to spread out the words so the same quiz groups do not contain the same words all the time.
