Buchstabensalat (logic puzzle)
Buchstabensalat, commonly referred to as "End View" or "Easy as ABC", is a logic puzzle.
A Buchstabensalat puzzle consists of a set of letters or " alphabet" (for instance, "A-E") and one or more empty cells in the form of a grid, where either end of some columns and rows are labeled with a letter in the alphabet. To solve the puzzle, one must place the letters of the alphabet in the grid such that
- every row and column contains each letter of the alphabet once and only once
- "looking in" from the end of a labeled row or column, the first letter "seen" (skipping blank spaces) is the letter specified.
