Imagine that someone has drawn a large number of latitude and longitude lines on the earth. These lines are separated by 1/60 degrees, or 1 minute. The intersections of these lines are called KNOTs.
Your mission is to unknot as many knots as possible.

+++ How do you unknot a Knot? +++
You can unknot a knot by simply approaching within a radius of 50 m of a knot.

+++ Gordian Knots +++
Most knots have fractions in their coordinates. For example, the latitude and longitude of the knot close to Apple Inc. are (+37.33333, -122.03333). However, the coordinates of some knots do not have fractions. Such knots are called Gordian Knots. The Gordian Knot closest to Apple Inc. lies at (+37.00000, -122.00000). Gordian Knots are unknotted in the same manner as ordinary knots.

+++ Play Carefully +++
How many knots can you unknot? However, it should be noted that approaching some knots could be dangerous. So, play this game carefully at your own risk.

+++ IMPORTANT +++
This App uses GPS in the background. Continued use of GPS running in the background can dramatically decrease battery life.
