First of all, this is my first post here and I am really happy to contribute.
J-Fizo (Free) was developed by Adam Błaszkiewicz. A couple of weeks ago, Nicola tweeted about this game and compared it to my game Sky Scramble, so I had to try it! Indeed, there is some resemblance but there is a big difference: while my game is geometrical (the distances are important), in J-Fizo the game is topological (distances are not important).
Let's get into business, J-Fizo (Free) was developed by Adam Blaszkiewicz. The game presents us with a network (or graph in mathematics), and on each node of the network we have a black token or nothing at all. The links of the network are colored, and for each color there is a button.
