TJ-wriggle puzzles ☕

The TJ-wriggle puzzles followed on from the original wriggle puzzles and quickly established themselves as the most popular variant. They are named in honour of Tom Jolly who devised the original mechanic and who helped co-develop many new challenges. The set featured below is based on the 6x6 grid and up to four wrigglers. The goal is the same in all cases, to release the blue wriggler through the gap at the bottom of the grid. Note that in these puzzles the grey squares are blockers, so the wrigglers effectively reside in a mini-maze.

Applet-runner plugin required

Drag the wriggly worms around the maze until you can release the blue wriggler through the light-blue gateway. You can drag by head or tail and it does not matter which end exits first.

Added to the collection in 2009 we also have the big-wriggle bonus challenge which celebrated the launch of the first Wriggle iOS app The app was later released for MacOS as Wriggle-3D in 2013.

Both apps were developed by Conlan Rios and perhaps one day will be refreshed and relaunched. In the meantime you can explore many other apps based on the wriggle mechanic by delving into Joel's Snake puzzle games blog. So much more to explore!

Hint: you can resize the puzzle frame after launch
