Stressless Kenken: 200 Mind-Stimulating Logic Puzzles That Make You Smarter

Nice

Awesome book helps in improving skill .......With answers

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.

A great way to pass the time and challenge yourself. Really fun to do. Quite addictive.

My fav puzzle books!!
