Sumo Kaboom



Bingo cards for the January tournament are available!

We play online BINGO every sumo tournament with about 500 people! You could win a prize by getting a kachi-koshi or make-koshi BINGO. Past prizes have included bookmarks, tshirts, tegata, pins, trading cards, star charts, cookies, calendars and banzuke, but one winner always wins a jar of homemade jam from Sumo Kaboom and a spotlight on our podcast!

Our sponsor joins us again for January and is providing a 2022 sumo calendar and a Hakuho fan magazine. Big thank you to bigSUMOfan!

The cards go quickly and the game gets bigger every tournament, so if you don't get a card this time, get on our email list for the next tournament. Sign up here. We NEVER share your email address and hate spam.



  1. Claim a card.
  2. Mark a wrestler when he gets 8 wins (kachi-koshi) and/or 8 losses (make-koshi).
  3. 5 across/down/diagonal of the same type is a BINGO (all kachi-koshi or all make-koshi).
  4. Send us a photo of your completed winning card by email ([email protected]) ASAP and feel free to share your good fortune with the world over social media.
  5. The 1st to kachi-koshi or make-koshi BINGO wins a prize. If you BINGO later (any kind), your name goes into a drawing for a prize at the end of the basho. SO KEEP PLAYING.


  1. It's the honor system. Be cool.

  2. Squares are filled with wrestlers who are listed on the current banzuke. If a wrestler never wrestles in this tournament, it's NOT a make-koshi or kachi-koshi. It's a dead square. Sorry. Sometimes, it’s just the way the cookie crumbles.

  3. Even if it LOOKS like someone else won, keep playing. Remember, every BINGO puts your name into the drawing for a prize.

  4. If your wrestler wrestles at least 1 day, his record still counts. He might be make-koshi, but he could be JUST the loser you need to win BINGO.

  5. Have fun and good luck! Ganbatte!
