If you find a true or false statement within the clues, type in the graph either the number "1" (one),which means the statement/clue is true, or the number "0" (zero), which means the statement/clue is false *(please see below). If a horizontal or vertical "section"  has a check mark in it, the rest of that row and column must be false and therefor should have all "0"s (zeros). Likewise, if a row or column has all but one block in a false state, then the last block must be a number "1"(one).  Note that a "section" is inside of the   --  or  |  lines, usually in blocks of 4 or 5.

Example:

• We need to match peoples first names with their last and from which country they originated.
• Clue:  Robert  met Mrs. Smith in George's country of Greece.
• From the clue, we know that Robert's last name is not Smith.  So where Smith and Robert cross in the graph, we would place a "0" (zero).
• From the clue, we know that George lives in Greece.  So where George and Greece intersect in the graph, we would place a "1" (one).
• Since we know that George is from Greece, we can safely put a "0" (zero) in all other countries under George.
• And so on...

Once you are confident that your solutions are correct, click the "Check Your Answer" button towards the bottom of the page. This will give you an immediate response if you are correct or need to try again.  All of the puzzles on this web page calculate the positioning of the "1"s to make sure that they are in the right slot within the graph.  You can have empty spaces where a cross-section is false (zero), but not where a "1" (one) should be located.
