Since the theme of his zanpakto is children's games, also Jushiro said it would be a bad idea if other people would witness his bankai. I don't know anything for sure, but my theory is that his bankai is based on the game hide and seek. My idea was that maybe anyone in the range of his bankai would go blind for a period of time allowing Shunsui to move or "hide" and then vision returning for a short period of time before everyone goes blind again. Shunsui could use this to position himself behind opponents as well as being able to prevent his opponents from getting a good shot at him.

This is just a theory but from the two things we know about Shunsui's bankai and his zanpakto it seemed like a decent theory to me, idk...
