Little trains with Linux games [ended]

I <3 ambidot

Well, solved. Without trying Q4 even. :p

solved

Solved thanks :)

But I think writing the answer for Q4 in one word should also count ^^

hints for people who don't speak gibberish?

Bump for solved! Thank you!

I have all but the last one :(

Waiting for hints for Q3.
Also I recognized Q4 immediately as something very dangerous! :p

It seems that Q3 have some nickname that I don't know :)

Bump for solved ;)

Bump.
A second train has been added.

bump for solved & thanks for the trains

Solved, but Q3/4 had me stumped

Too bad I'm never going to finish it.

View attached image.

bump!

I immediately recognized Q3, but Q4... I am stumped with that one. Does it make any sense? It sort of looks like a regular expression...
EDIT: Found it. Took me lots of Googling, lol

Wee solved :3

solved by a windows user :D
Bump

Never saw anything like Q4.. Dont know where to start searching.

Finally an easy puzzle and it's Level 2 :(
Also, Q3 should have more variations as correct answer imho.

Bump for solved :)

Nice, thank you nuking.:)

Bump!

And a bump.
Train one ended, keys sent.
