Use numbers from a clock (1 to 12).
A number’s ‘neighbor’ (above, below, left or right, except if separated
by a maze wall) must be one of the two numbers nearest on a clock face.
As in Sudoku, some numbers are left in place in the Hour
Mazes to give players ‘Hints’ as to the solutions.
In the Flash presentation, the Hints are indicated by a small, white box in the upper-right corner of their square. The Hints are fixed and can not be removed using the Blank Button.
The Hour Mazes are arranged by grid size, smallest to largest.
However, within each of those groupings, the puzzles are not arranged according
to any category of challenge.
