Four colored playing cards are provided for each suit, so that the suit can be seen even from the reverse side. Repokes (missed plays) can be seen in real time by other players, and must-follows can be corrected.
It is as simple as that, but when it came time to look for “playing cards with the entire surface filled with color,” it was hard to find, and we have not been able to make it for a long time. I also searched for the bycicle-playing-cards sold on the above page, but no hits as of 2025.
In the midst of all this… I found a good one in my daily search for a deck of cards.
Found in Shein !

It’s glaring 😅
The design is what it is, but the price is pretty safe, as you can buy 4 of them for about 2000 yen. And the even better part is that they are bridge size. In a trick-taking game, you basically have 13 cards in your hand, so it’s nice to be able to make it with bridge-sized playing cards.
I’ll actually make it.

And so on, divided by suites…

Made 4 sets so that the colors don’t cover each other. Completed 💡
Games you can play
The following page introduces a variety of games that are classified as trick-taking games, which we believe are basically enjoyable.
- Nerima Oyako Board Game Association, Must-Follow Practice Game (Japanese page)
- Gokurakizm,Trick-taking for 1 person: Gosankyo (Japanese page)

I have a feeling that it will be solely for one person for Gosankyo and for Oneonta Whist, but I would also like to use it to play Naps and Hearts with my children.
