Logic Puzzles: Unfair Puzzles

All 60 logic grid puzzles put every devious clue type to work at once — conditionals, a planted lie, and statements you have to count — and then break the promise every other book here keeps: deduction alone will not finish them. Somewhere in each one you must pick a possibility, follow it, and find out. One solution each, and exactly one — but you will have to gamble to reach it. Clear clues, roomy grids, and a friendly how-to-solve guide.

Coming soon to Amazon.
