So, a bunch of good things happened recently and I didn't have enough time to make a celebration train for those.
I pushed myself to level 6, I gave away more games than I have in my library (thanks to perrolijo for pointing that out recently, although I got a bit confused because of a number of wins and a number of purchases on the exploration sale, but this should be quite definitive now), I got my first paycheck on a now job, the firs official meeting with my boss and colleagues went pretty smooth, I'm able to solve some puzzles again, I won a wishlisted game today and maybe a few more things I can't remember now.

To celebrate this I'm running a bunch of simultaneous trains, a puzzle and a whitelist giveaway as usual.

Just to remind the rules:

• don't share the links/answers
  - first 3 solvers which haven't been yet whitelisted will be if they will comment in the post-puzzle giveaway
• ranting and frustration appreciated
• hints will be gradually provided
• commenting not required, but you can say something (I won't blacklist you in either case)
• 1 week running time
• trains are level 1+, post-puzzle giveaways have no level restrictions

The post-puzzle prises are a recently bundled AAA game and a non-bundled brand new indie game.

So, happy multitrack drifting.
