Righto. Going to call this in.
We had 12 compilers this time with a myriad of ways to approach SPARE. Lots of good ones, but the ones that made my shortlist were :
tyke51 @30
pedagogue @18 and
paul @5
But our winner this week is pedagogue's @20 :
" Odds are slim "
Simple, yes, but I do like a nice succinct surface, and this one fitted the bill nicely.
Congrats pedagogue and the runners-up !
The prize this week is a tickle on the ivories :
