solved it with 3 complete guesses! Just got lucky I guess...

Nah, not lucky. There may often be things you have to make educated guesses at... but these are 'educated' guesses. You know enough to anticipate a set from 2 or, better yet ,3 constituents, and then figure out the other(s). That's often the way the game goes! ;)

So... well done, algsjd.

A wonky clock adds to the flavour.

O, yeah, thanks for the heads up, Dave C! This was meant too to go under the Antarctic flag... fix please? Antarctica is the land of wonky clocks.

SCTV? who's ever heard of that
