About Region Select

“Region Select” is a new puzzle game for Android discovered by
Osaka City University Advanced Mathematical Institute using advanced mathematical knot theory.
Although its rules are as simple as Sudoku and Rubik’s Cube, “Region Select” will challenge you to
think ahead like Japanese Go.

[Game explanation]
At the beginning there is a knot figure. The spaces between the lines are called “regions”,
and the places where the lines meet are called “crossings”.
Each crossing has a “lamp” which can be turned on or off by clicking on the region bordering it.
But when you click on a region, all of its crossing lamps change! If a lamp is already on,
it will be turned off, and if a lamp is off, it will be turned on.
The goal of the game is to light up all of the knot’s lamps by clicking on different regions.
Mathematical knot theory proves that each knot figure can be cleared.

[About knot theory]
Knot theory is a branch of mathematics studying tangled string knots to determine such things
as whether a knot is actually tied or untied,
how a knot can be untied, and what kinds of knots exist, etc. Nowadays knot theory is studied and used
around the world not only in mathematical research but also in physics, chemistry, and biology, etc.

A decent graph-theoretical challenge. However, purchases for access to the hard challenges won't work for me :-/

I've solved all the free levels. It's a good brain twister, but not worth $ for extra levels.

I haven't found a puzzle this good in a while. The app is also ad free and does not require any permissions it doesn't need to do its job. It definitely deserves to be among the top free games.
