In celebration of the arrival of our new Knight’s Atari t-shirts, we are offering a free t-shirt to the first person who sends us in completed solutions to BOTH of the puzzles below. Sadly, we do not yet have the functionality to enable you to fill in the puzzles online – that would be pretty cool, and is something that we have planned for when we finally get knightsatari.com off the ground – so entrants will have to rely on their own ingenuity to send in their solutions to knightsatari[at]gmail[dot]com. That will probably be more challenging than completing the puzzles, to be fair…


 Tic tac logic

The object of this puzzle is to fill in the remaining squares with Xs or Os, such that:

  • There are no more than two consecutive Xs or Os in a row or a column.
  • The number of Os is the same as the number of Xs in each row and column.
  • All rows and all columns are unique.


A Skyscraper puzzle consists of an NxN grid, where each row and column must contain all of the numbers 1 to N, each representing the number of floors in that skyscraper. In addition, the number of visible skyscrapers, as viewed from the direction of each clue provided along the edge of the grid, is equal to the value of that clue. Note that higher skyscrapers block one’s view of lower skyscrapers located behind them.


As you can see, these puzzles should pose no difficulty for Knight’s Atari’s intelligent audience, so get your entries in quickly!
