The Turing Tests Series
The varied puzzles in this collection all feature numbers, and are designed to provide a stiff test for those that like to be stretched. There are three levels of increasing difficulty, with the third level being for the "expert" solver.
Some nice puzzles that are fun for the reader to do, and also nice for the teacher looking for warm ups or end of class/term activities with varying degrees of difficulty.
