Fukutarou says that English rules will be available by the end of November 2020, but here's a summary of the gameplay for now:
At the end of the game, whoever has the most points — or more frequently the fewest negative points — wins!
Nine Tiles: Sanrio Characters will include rules in Japanese and English, but will be sold in Japan only, presumably due to licensing restrictions.
• Oink will also debut a new game at the show — Hey Yo: The Card Game to the Beat, a design for 2-10 players by Takashi Saito. Here's a short description that's somewhat minimal on gameplay details:
Hey Yo includes two identical decks of cards, so instead of playing a co-operative game with 2-5 players, you can have 4-10 players split into teams to compete against one another.
Your goal is to co-operate to achieve a high score. On the beat, you play one of your four cards in hand to the end of the line, then draw a new card. If you miss playing on the beat, you'll play one fewer card total and probably miss out on points. Each card has five lines on it, so when placed together, they look like a music score. Sometimes a line is blank, sometimes it has 1-2 colored symbols on it, sometimes it has an X over the colored symbol, and sometimes the symbol has a scoring halo around it.
Once the music ends, you advance from the first card onward with a pawn, stopping whenever you hit a scoring halo. You then count backwards to see how many symbols of that color (shape) there are before you hit an X, with the symbol inside the halo also counting. Sometimes a halo has an "x2" mark to indicate that you double the score for that halo. Some cards consist of nothing more than a "cancel" symbol, which tells you to ignore Xs on either side of that card. Combine your cards to score lots of points, with anything higher than 100 being excellent!
