One of my qualms about getting myself some Perplex City cards was that I’d either never look at them or I’d become obsessed. But I seem to be finding a middle ground, taking the occasional look at my unsolved cards, and not itching too badly to get more.
The thumbnail (click it for full size image) shows my favorite puzzle so far. I’ve just solved pictogram 2 to complete the card, and been to the Perplex city site to enter my solutions and verify that it was correct.
