Step-over sequence mazes
Repeat after me red-white-blue, red-white-blue... and so on. Enter the maze centre-bottom, step over the next colour in sequence to an adjacent cell, repeat until you can finally exit centre-top (always finishing with blue). That's all there is to it. This is a simple sequence based multi-state maze, which works delightfully well, and I have spent many happy hours trying to squeeze the longest possible path out of the grid, while still providing a good maze.

Enter centre-bottom, exit centre-top, step over the lines in order red-white-blue, red-white-blue (and repeat). The stepper icon will change colour as you move to indicate the colour of your next step (in the example on the left the next step has to be across a blue line). If you get stuck you can either back-track or restart.
Use the puzzle drop-list to select a puzzle.
Use restart (action) or the space key to reset.
Use cursor keys to move (or click on the screen).
Your last three moves are highlighted as a guide.
A move can be undone by clicking on a highlighted square, or by pressing 'u' or by back-stepping using the cursor keys.
The first prototype (red-white-blue) maze, in action at Moulsford village green at one of our local village parties (June 2005).
The maze was inspired by the purchase of a cheap ribbon 'door' made of lightweight plastic strips. It was cut to pieces and stapled together again in an afternoon, and only survived a couple of outings.
The second prototype (red-blue-yellow) at final manufacturing stage (Oct 2005). This version is far more durable being made of heavy-duty polypropylene webbing, riveted together.
Four of these webbing mazes (two 4x4 designs and two 5x5 designs) were built for the Techniek Museum Delft, for use during their national Science Day in October 2006.
The second prototype in action at Gathering for Gardner VII in Atlanta (March 2006). Being road tested here by great logic-maze master himself Robert Abbott (www.logicmazes.com).
