Curiously, Nilay Lawson on her Facebook timeline in one instance uses the phrase 'playing dominoes' in a context that makes it seem to me as though not meant literally. It appears along with several photos that I can't make sense of.

Thoroughly enmeshed in the more intimate Alefantis circle, Lawson may conceivably have used the conspicuous trope in the same as-yet-undeciphered but decidedly non-literal sense as John Podesta in the Wikileaks emails, further indicating that it may be an established jargon within like circles.

Nilay Lawson is, so far, most famous for having commented on Alefantis' 'killroom' picture.

Beyond that, some of Lawson's artwork is reproduced here in case of interest, taken from her Facebook account:

(Without providing concrete refutations, please don't clutter with redundant objections to the effect that this obviously doesn't 'prove' anything and she could theoretically have used the phrase for any legitimate reason. At the moment this is about recording and investigating. Thanks.)
