 Hi, Willem here.

 In this part I will talk about my experience during the CTF and The
 collaboration between me and Loek.
 
-This was also my first CTF, just like Loek, because of this was quite
-uncertain about my skill level. For example, I have no experience using Linux
-systems, but from what I learned before the CTF it is quite essential. My fear of
-not being able to do any off the challenge disappear quickly after we had completely 
-the beginner challenges.
-With a simple sql injection I got my first real flag.

 So, we didn't really know who was doing which challenge, but because we're a
 team of two this wasn't a big problem.

+### misc/the-substitution-game
+
+One challenge I spend a lot of time on was __The substitution game__. In the
+substitution game you had to substitute certain parts of the input string to
+get the desired output string. I got to level for of 6. Level 1 and 2 to were
+really simple, but at level 3 you started to need to really understand the
+game.

 ```
 level 3:
 initial: aaaaaaaaaaaaaa (the amount of a's varied)
 target: a
 ```
-The solution is really simple, but it's pretty hard to get to it.
-You want to remove 'a's so I started with ```a => ``` , this turn all 'a's
-to None and left you with an empty string. The problem is you can't substitute anything in 
-an empty string. The solution was ```aa => a```, this removed an 'a' every time 
-the initial string got checked. To get this solution you had to realize,
-that the program would always substitute the first instance it would come 
-across, and the program was set to do way more than needed substitutions.
-This would come handy in the next level.

 level 4:
 initial: ggggggggggg (the amount of g's varied)
 target: ginkoid
 ```
+
 After completing level 3 this level looks very easy, just substitute the g's
-like before ```gg => g``` and turn the last g into ginkoid ```g => ginkoid```
-, but this didn't work because of the way the program worked, after getting to a
+like before `gg => g` and turn the last g into ginkoid `g => ginkoid` , but
+this didn't work because of the way the program worked, after getting to a
 valid solution I didn't stop and the single g in ginkoid would also change to
-ginkoid. You would get infinite ginkoid.
-The solution was:
-```gg => ginkoid; ginkoidginkoid => ginkoid; ginkoidg => ginkoid```
+ginkoid. You would get infinite ginkoid. The solution was:
+
+```
+gg => ginkoid; ginkoidginkoid => ginkoid; ginkoidg => ginkoid
+```
+
 I began with noticing you couldn't just change the g, because that would also
 change the g in ginkoid. so double gg becomes ginkoid. We have to use the same
-trick as in level 3 to gain only one ginkoid ```ginkoidginkoid => ginkoid```
-because of the way we changed the single g's to ginkoid it would only work
-with an even amount of g's. In the case there was an uneven amount of g's
-we would be left with ginkoidg, so we remove it ```ginkoidg => ginkoid```.

 I found this challenge really enjoyable and during this challenge I noticed
-that I most enjoy the puzzle aspect of computer science, puzzling for hours
-to fix a bug and then finally finding a solution.

-I didn't complete many challenges and wasn't really able to help Loek, but
-I really enjoyed the CTF. It's a really fun way to test your skills and 
-knowledge. In the end I'm really happy with the score we (mostly Loek) got
-and I think I’ll take part in other CTFs in the future.
