Stressless KenKen: 200 Mind-stimulating Logic Puzzles That Make You Smarter: Volume 1 Paperback – 5 April 2016

Variety of puzzles, enjoying working my way through them.

Really like this as it does what it says - no stress puzzles for those times when you just need relaxation.

I am thoroughly enjoying doing these puzzles, it is good to have different difficulty levels which I swap between depending on my mood.

Too many easy puzzles
