Logic Puzzles For Children: Easy as ABC Puzzles - Best Logic Puzzle Collection - Paperback

by Ted Warner (Author)

Easy as ABC ("ABC End View", "Last Man Standing") is a square grid, whose cells are to be filled by a range of letters (e.g. A through E), with each different letter occurring exactly once in each row and column, and the other cells remaining empty. The letters outside the grid show which letter will come across first from that direction.
