## Alpha-Grid

Logic puzzles require you to think. You will have to be logical in your reasoning.

 Puzzle ID: #44313 Fun: (2.52) Difficulty: (2.61) Category: Logic Submitted By: cnmne

20 cells are arranged in a 5x4 grid. The cells are occupied by 20 birds (10 different birds, a pair (2) of each).

The cells are labeled as follows:
ABCDE
FGHIK
LMNOP
RSTUW

The birds are: albatross, bunting, cardinal, chickadee, finch, flamingo, hawk, magpie, penguin, and swan.

A bird can only occupy a cell if the cell is labeled with a letter that is in the bird's name. For example, a hawk can only be in cell: H, A, W, or K.

Each pair of birds must be in the same row or the same column.

Where are the birds located?

1) Determine the locations of the swans. The only cells that are in the same row/column are in row 4.
2) Determine the locations of the hawks. One of the cells is eliminated because it is occupied by a swan. The only remaining cells that are in the same row/column are in row 2.
3) Determine the bird that is in row 1 column 2. Placing the bunting in that cell will lead to a dead end. Therefore, an albatross must be in that cell.
4) The remaining cells can be easily filled with the remaining birds.

Row 2: finch, magpie, hawk, finch, hawk
Row 3: cardinal, magpie, flamingo, flamingo, penguin
Row 4: cardinal, swan, bunting, bunting, swan
