RULES Place any number, from 1 to 12, in each square of the maze. Numbers must run in some sequence from 1 to 12 or 12 to 1, like on a clock face. Each number’s ‘neighbor’ — any square above or below, to left or to right, NOT separated by a maze wall (diagonals are not neighbors) — must be one of the two numbers nearest on a clock. For instance, a 6 can only be next to a 7 or a 5. The number 12 can have either an 11 or a 1 as neighbors, and a 1 can only have a 12 or a 2 next to it. In a 12x12 maze, you must use twelve of each of the numbers to complete the puzzle. In other words, you must us a total count of twelve ‘sets ' of 1 through 12. However, they do not have to be in twelve continuous ‘runs' of 1 through 12. In each maze, the grid size determines the solution requirements, as all mazes are multiples of twelve. For instance, in a 6x6 maze (36 squares), you would have to use three of each of the twelve numbers of 1 through 12 (12x3=36) to solve that puzzle. Again, they do not have to be in three continuous ‘runs’ of 1 through 12. (See 'NonContinuous Solution Illustrated' on Path Strategy page for an example.) ___End of Rules___ The mazes emerge from
grids built from multiples of twelve. For instance, but not limited to, 6x6, 6x8,
6x12, 8x9, 6x24, or 12x12, etc. See also our 'Poker Maze' puzzle. We suggest you read: and before you start.  Interactive Instructions Below: Click on this link to go to: Opening Screenshot

Insert a number by clicking on any square which does not have a preset Hint number. The Green Number Button indicates which number will be inserted. Choose any number you want to insert. After inserting a number, the Green Highlight will advance to the next number. To change any number inserted, just click over its square. Or just click continuously on a square until you get the number you want. The Blank Button clears any square. Hints, which are preset and indicated with a small white square, can not be changed. The Statement above the Number Buttons shows the total count of each number required to solve the current puzzle. For instance, in Puzzle No.1, “You need two of each number” means that two each of the twelve numbers – one through twelve – are required for the solution. The Small Black Numbers beneath any Number Button indicates the total count already inserted. For instance, in the opening screenshot for Puzzle No.1, the number buttons One, Five, Seven, and Nine each have a small black number ‘1’ beneath them. These indicate the Hints already inserted and that each of these numbers has already been used once.
The Blue Up & Down Arrows are used to scroll and choose any of the 97 puzzles. A Big Red Number shows the puzzle chosen and displays New Game above it. The mazes get larger the higher the number. You can also use these Blue Arrows to ‘reset’ a puzzle. If you want to clear all the previous numbers you have inserted just go arrow up and then arrow back down. ‘Check!’ Button displays Three Error Zones: Click on the ‘Check!’ Button if you have filled the entire maze with numbers but the ‘Well Done’ sign Does Not Flash! Flashing Red Highlights surround Insert Buttons at top and indicate any incorrect number count. Red Arrows indicate mismatched number sequences between two or more squares. Flashing Yellow Squares reveal empty squares. These error indicators will fade away in a few seconds. ‘Solution’ Button
reveals the solution and
displays ‘Computer Solved’ at the top. (Note: You can't go back. So, if
you want to compare what you have to solution, either write it down or
open two browser windows.) ‘Rules’ Button will open a frame with a condensed description of the rules and a link to our Home Page. Click the arrow on the right hand edge of this window to close it. Screen displays ‘WELL DONE’ when you solve a puzzle! NOTE: Puzzle No.14 is the only one with No Hints. Puzzle No.5 and Puzzle No. 81 have only One Hint each. Puzzles No. 5 and No. 7 are maybe the easiest to solve.
