There’s a fabulous variety from all around the world, so you can challenge yourself with something different every day. And all it takes to solve these self-contained conundrums is a healthy dose of logical thinking plus a touch of simple arithmetic—no dictionary or other reference required, which makes them perfect for working on anywhere.
