To apply your skills in the solving of a logic puzzle.

What you'll likely encounter is that there will be more indirect clues (ie knocking something out directly from a clue in one area, which can have secondary elimination moves elsewhere on the grid). Some of the existing puzzles have aspects like this, but may not have as heavily utilized them as central means to solving the puzzle.

Remember, keeping track of what has been eliminated is just as important as tracking what has been identified. A lot of trouble or dead ends emerged when people were not keeping full inventory on grid box eliminations.

The Springfield County Bird Club met today, and several of its members brought their newest acquisitions. Match each person to their newest bird - determine its species and the town and month in which it was purchased.

1. Of the bird purchased in Camden and the parakeet, one was bought in January and the other is Celia's.
2. Molly's pet isn't the lovebird.
3. The finch was bought 2 months before the bird purchased in Upton.
4. The bird purchased in Linda Mar is either the bird bought in February or the bird bought in March.
5. Of Alberta's pet and the bird purchased in Truesdale, one was bought in June and the other is the lorikeet.
6. Molly's pet wasn't purchased in Truesdale.
7. Of Kellie's pet and Alberta's pet, one is the finch and the other was bought in June.
8. The six birds are the bird bought in March, the bird purchased in Truesdale, the bird purchased in Upton, the finch, Celia's pet and the macaw.
9. Kellie's pet wasn't purchased in Julian.
10. The lorikeet was bought 1 month after Sara's pet.

Logic grids are not the only form of logic puzzle; here is another one that relies heavily on logic and reasoning in order to sift through.

A word math puzzle is one where the numbers 0-9 have been replaced with various letters of the alphabet; it is your task to determine what number each letter maps to, and report that to me in the project submission.

For this sort of problem, you will likely want to take notes; all the various little tests you concoct to prove or disprove some relationship. This may also take a bit longer and seem more overwhelming, but really, it is just longhand math :) Remember to attack the problem in pieces, and not head-on all-at-once.

Practice some similar math problems to derive patterns so that the seemingly unfamiliar letters performing math can start to make more sense.

With the logic grids you put your logic skills to the test, with the word math you math skills. Here, we will explore various other types of puzzles, often combining both logic and math skills to solve, but also exercising different aspects of your deduction/induction skills.

Enter numbers into the blank spaces so that each row, column and 3×3 box contains the full sequence of numbers 1 to 9.
