Tile puzzles
The tile puzzles are tiny, elegant, jigsaw-esque puzzles, that completely defy their innocent appearance. Each puzzle consists of a small number (typically less than 12) monomino and domino tiles each depicting a network-like pathway terminating in up to 6 edge connectors. The challenge is to arrange the tiles so that the pathways all join up to form a closed network. All the tiles must be used but the final solution can be any shape.
New October 2022: The latest iteration of the tile-puzzle genre is now available in a print-and-play format. Read more about its long evolution below or teleport straight to the end result: Space-station MMXXII.
Tile puzzle history (added October 2022)
The tile-puzzles have a long history.
First conceived in 1981, a single 12-piece puzzle made its public debut in the local village newsletter as a print-and-play puzzle. A mass distribution that reached about 100 households.
In late 1997 the classic four tile-puzzles were designed and launched here at clickmazes, as interactive puzzles in applet form. They were accessible right up until 2016 when the last few browsers finally pulled the plug on applet support. The image on the left is an illustration of the applet running locally, on MacOS, using the java appletviewer utility.
After a period of downtime the original applet is now accessible again thanks to the cheerpj applet-runner browser plug-in.

In 2002 we branched out and decided to construct several sets of physical tile-puzzles using printed paper stuck onto MDF. The original four puzzles from 1997, plus a small yellow puzzle.
Twenty years later these puzzles are still in regular use and have made outings to many national and international puzzle-gatherings.
In 2020 clickmazes was relaunched with a swathe of old and new material. To celebrate this event two new puzzles were released called the duplex-dilemma ☕.
After a period of downtime the duplex-dilemma challenge is now accessible again thanks to the cheerpj applet-runner browser plug-in.
Over the years I've corresponded with several people who have written tile-puzzle solvers. The first would have been Graham Rogers circa 1990, then Timothy Bahls (2004) and Matthieu Haller (2006). Plus one or two others that I have since lost all record of.
Timothy Bahls' solver was written as an applet with a visual UI, which made it my tool of choice. Over the years I refined and rewrote large chunks of it to satisfy my occasional craving to explore more puzzle sets.
In 2019 I set myself the challenge of finding a pack of core tiles that could offer a variety of puzzles across the difficulty range. The goal was to maximise the number of uniquely solve-able challenges while minimising the total number of tiles in the pack.
Three years later my efforts eventually resulted in a pack of 15 tiles that offered at least 30 distinct puzzles. The solution on the left is one of many solutions for all 15 tiles (definitely not unique!).
