It's not for me. I quite enjoyed the first handful of times I tried it, but then got distracted and didn't go back. Failed the crucial 'can't wait to get back to it' test, alas. But then I started to see people posting their 'successes' all over social media, and was glad. I didn't know what they were before - now that I do, it makes not doing the same so much more satisfying than actually playing the game. Please tell me you're not doing that, Diane?
I remember enjoying the little game with coloured pegs that probably inspired it. That was fun....
