I played Scrabble by soy-based candlelight with hubby. I think I won, but it was really hard to see the letters.
It's mostly just a symbolic gesture to participate. We normally go for a walk around the neighbourhood to see who else is joining in and I always love to see the houses with candles glowing, people playing cards in the front window, or out walking the dog. It tends to be the biggest and richest houses that have every light on, with TVs blaring even though nobody's watching.
