Steam Code Drop Puzzle

letter or num would really help

Doesn't work

But it's invalid because last part has 4 instead of 5

Missing a key

its a puzzle, cant you guys read....

Of course it's invalid, it's a puzzle, solve it!

Even if it's a puzzle, it should be another "*" between the last 4 digits i guess

Key is not possible, even if it is a puzzle, tried them.

already try all number and ltter...all invalid

Well, either he did some shit wrong or he's trolling...

36 times 36 times 5=6480 possibilities.

Fixed Sorry. Derp.

thanks!
it was "2"
