These are series of enigmas games.
Enjoy thinking about puzzles.

One series of puzzle is included for the moment : you will have the pleasure to try to complete some Eulerian Graphs (by passing through each of the edges only once, without lifting pencil).
After some practice, you can be confronted to the online time challenge, which permit to compare your records with other players in acheiving all the 8 graphs quickly.

More types of enigmas are coming soon…
