I have been using this model for research and interface since 2004:
Islam is signal, symbol and code.
Words spoken reside under clouds of thoughts pregnant with meaning.
The beads laid out between the players are Qutbian with civilizational stones
I play a red. You counter with a red.
I move the opaque to the center of the table. You counter with the same.
The black stone. It is the stone which must be played last.
