So if the highest number on a domino side is 6, then it looks, by the pattern used, that they added 6 more dots to a 5. See pic.
So original domino had a 5 over 6.
They added : * * *
* * to *
* * * *
Sorry if dots don’t line up. Phonefagging this.
The domino could also mean 11…6 = Q116.
Fits with the FAST them also in Q3111 (visible scrabble points).
