I was wondering if there exist any physical stones that have markings often seen in game reviews such as triangles, circles, X's, or squares. In the absence of a computer for review, I could see these as kind of nice for teaching purposes. Has anyone seen such stones anywhere? Maybe a set of 10 apiece with a circle for instance.

Hi Sivak,

In the absence of a computer, may I suggest using the organic pointing devices that are attached at the periphery of your hand.

I think sets for the blind have stones with humps and dips in them.

Well, the symbol stones could be used to play out a sequence without having to fully memorize the position prior to said sequence.

You can't manifacture slate & shell stone like these, yunzi or glass would probably be very tricky, and plastic would be the easiest to manifacture, but far from easy. So I doubt there's a market for it to be worth the hassle and cost.


Why not using stickers of color instead?

So, take an unused set of stones, a set of small color dot stickers, and you can make your own color coded stones !

Hi Sivak,

Yes... it's an unusual situation.
The markers have their advantages when using a computer;
but if you're using a real set, with your hands, the situation is different.
Somehow markers on real stones feel like the cart before the horse, to me, but YMMV.

I've never seen anything like that, but perhaps you could try some different colored stones. Mr. Kuroki has clameshell stones dyed pink and green, and I've seen a number of colored glass sets online. There's also semi-precious stones in a variety of colors (I have access to those if you're interested).

What might work best though is a cheap but functional alternative like some glass gaming markers; the kind that are popular in role playing or tabletop gaming. Chessex sells a variety. They're flat on one side with a rounded top. The major disadvantage to these, however, is that their diameter is much smaller than standard stones.

Can be achieve by using single-convex Chinese yunzi stones. Flip over to the flat size to play out trial sequences and leave the actual play with the right side up.
