Final results will be available on Monday.

The puzzles are taken at random among the thousands present in the site.

Therefore the difficulty of them can vary from easy to hard.

Even if the average time to complete all the puzzles should be not more than 60 minutes, You have NO TIME LIMIT to complete the contest.

The time will be calculated as sum of each puzzle solution time (from the first opening to its solution).
That means that when you open a puzzle you must solve it: you can not browse all the variants and after decide where to start.
People that solve on paper should print a single puzzle, solve it and then open and print the next one.

IMPORTANT!!!

When you finish a puzzle you must wait for the resolution time to appear above the grid.
Sometime it will take a few seconds, depending on the load of the line / server.
If you choose another grid before you get the message from the server, the time is not recorded and the server does not retain record of the solution of the grid.
