Nope, but it's related to it (i.e., this is the DLC for the giveaway game).

I've set this to begin after the puzzle giveaway ends because it's fair to give the winner of that a chance at this as well.

There will be another puzzle giveaway you might be interested in soon, though.

The answers will be posted after the next puzzle is solved.

The giveaway for the full game (which ended earlier today) was in the form of a puzzle posted here. You can still try to solve it, but there will be no more hints than there are in that thread and this one for that particular giveaway. However, if you get to the end of it, you will get a head start on the next giveaway (which starts on March 20 at 00:00), because the format of that and two of the clues will be exclusive for those who made it to the first puzzle. The remaining three clues will be in the forum thread that I'll open at or around that time, so keep an eye on the forums as well. The forum thread will not contain the format, though, to decrease the chances of people getting in by brute force.

However, there will be some chance for those who don't have the time or the desire to solve that puzzle, but are still interested in the game that will be offered. More details on that as events unfold.
