Ruckingenur II

Now available: Ruckingenur II, the latest game in my Games for Engineers series!

In the style of the first Ruckingenur, Ruckingenur II is a game of β€œrock and roll” reverse engineering of electrical circuits. Unlike the first Ruckingenur, Ruckingenur II is a full game, complete with multiple levels, a soundtrack, and live-action video sequences. Help can be found inside the game. Download link below!

It’s worth mentioning that this requires Windows (or something compatible) to play, along with the .NET 2.0 Framework. You should also have the sound on!

    It took me about 7 tries to beat the bomb at the end, not counting accidentally pulsing the detonator because my mouse jumped and grabbed the wrong point. So… Yeah, amazing game. I can’t wait for more.

    I actually finished this first then went to episode one. Both are great games and I’m eagerly awaiting episode 3. I did encounter one small bug in this one (R II) in the last mission. If I end up blowing myself up and then relaunch the mission, sometimes I am unable to move the probes and I need to relaunch the mission to reactivate them. The time to deactivate the bomb is a little bit tight if you are using a laptop joystick (wee button in centre of keyboard) as it is hard to move and select but it can be done with a normal external mouse ok. Sorry if that’s a little vague but I don’t want to give the game away and I hope those who have done it know what I mean. Thoroughly enjoyable game though. Many thanks for publishing it for us.

    This game was awesome, i can’t wait for more levels. I thought it would be kind of cool if you could some how incorporate soldering wires or other stuff like that, and a level editor would be awesome. I loved the videos before each mission, although a way to skip them would be nice *had to watch the bomb one a few times* This is a n00b question but i can’t help but ask, is there really something like the “hypermeter” though, where you can see the values of the registers on chips?

    There’s a protocol called JTAG that’s used for testing, debugging, and programming IC chips. That, along with protocols like I2C that allow you to read and write control registers, served as the inspiration for the debug interface.

    Really, this game was a blast. Out of curiosity, what inspired you to make this? How long did it take? Anything specifically difficult in making it?

  68. Zach's Gravatar Zach
    August 31, 2008 at 1:19 am | Permalink

    Zed: Inspiration? I’m not sure. One of what I consider to be the core mechanics of Ruckingenur, the debug register system, is something that I came up with a long time ago, probably from learning about something similar with electronics or computers. I vaguely remember coding up a game prototype in Visual Basic years ago that involved hacking an electronic sign and a microwave by writing to registers. Between another game prototype and Ruckingenur I, I was able to refine the mechanics a bit, resulting in Ruckingenur II. When I finally got down to working on Ruckingenur II, it took me about two months. I created a bit more content than you can see in R2E1, and meandered a little bit during the whole creation process. The hardest part of making R2 was figuring out how to end the game. As I’ve stated elsewhere, I planned for and designed more levels than are featured, but failed to make the last three what I wanted. After struggling with them for at least two weeks, I figured out the solution to my problem – release what I had finished up to that point as Episode One, see how it went over, and then if deemed a success (holy crap yes!) make more. I’m also not very good at art or acting, but those were slightly mitigated by using super-pixelated art and putting captions on the videos instead of talking.

    I’m not sure if this is a good thing, but I just finished it in under half an hour… with no knowledge of circuitry or really how any of the chips work xD Now, admittedly the town was blown up 4-7 times, but hey! They should have gotten a professional! The main reason I found it easy in the end was that I realized how to reset the timer on the bomb – that felt like a glitch. Like ZeXr0 I had it crash on level one when I clicked on the screen to edit the registers. I’m on 32 bit Vista Home Premium, .Net 3.0 I believe.

    Great game, can’t seem to do the bomb. Maybe I’m just not fast enough. Oh well, I still think it’s a great game. Can’t wait to see the next. Just one thing. Please, no time limit style challenges. They make for a good game, but can be Incredibly Infuriating. But still, can’t wait. Keep up the good work.

    If you liked this, check out the level editor. You can build your own levels. It requires some simple scripting, but that’s paltry to the satisfaction one gets from stumping your friends with your own levels. And even better then that, Zach plans on coming out with a community edition, with user built levels. Can’t wait.

    Love this game. Even if i do not know anything about electrics and this stuff i managed to beat the first level XD The only problem i got was that the game windows was to big for my 1024×768 notebook display. Didn’t found a option or anything similiar to make it little bit smaller.

    The messages are encrypted with a daily key. In other words, if I type in the same thing on two different days, they will come out totally different. The intercepted message wasn’t sent on the current day, so figure out how to make the thing _think_ it’s the day it was sent.

    I just finished the game. at first I didn’t get how the game works, but after I found out I rushed trough level 1 and 2. level 3 was a little bit harder because the machine changed the putten in date back to the normal date the whole time. And the bomb… that one was really hard. I blew my self up 7 times before finding out how to get the challenge code and after that I blew myself up 8 times, because of my slow computer. and the 16th time I was quick enough to save myself, luckilly.

    If you’re having trouble getting the game to run on 64-bit windows, try running the CorFlags utility on it with the /32BIT+ option. It seems that .NET is using the 64-bit CLR by default on the executable and throwing a BadImageFormatException when it runs into the 32-bit SdlDotNet library, probably because it uses P/Invoke and such.

    Looked over at the comments after finishing. This was fun, but it didn’t last very long. I thought I was going to have a lot of trouble on the bomb level, but I got that after two tries. I’m having way more trouble on KOHCTPYKTOP since I have NO electrical / hardware knowledge. I should go comment over there as well. Nonetheless. The window size caused a few minor problems but was fixable. A LOT easier to pick up then some of the other games. Nonetheless, well done. I’ll try and rate and/or constructively criticise as I complete each game, though I’ll probably get some hangups on those that require background knowledge, since I’m trying to avoid looking at the comments, as they spoil a LOT.

    Runs nice on Linux (wine + mono24 cca 500MB of wasted HDD space πŸ™ )
    There are some glitches, thought…
    a) canceling the 4th level with ESC, waΓ­ting >10 seconds and then clicking “exit” “wins” the round
    b) restarting 4th level sometimes fails (no probes and game is unresponsive to clicking, after final blow the game crashes)
    ps: having no keys on “numeric pad” sucks… I cannot type fast enough on those in line (and I’ve to hold SHIFT on czech keyboard layout)
    => i’ve installed package “xmacro” and wrote 1 macro (consists of “sleep 4” and “xmacroplay-keys”) per challenge and then simply executed it
    Can you please enable numpad AND/OR make linux version? Thanks…

    It works nearly flawlessly with mono+libmono-winforms (no Wine required to play)
    BUT because of the unwise keystrokes handling I cannot use *ANY* numeric keys
    numpad – no response, top row of keys – no response (even if combined with modifiers like alt, ralt, shift, control or winkey)

    When I try to run it (I’m in Windows Vistax64), It tells me there’s something wrong and shuts down without an error message. To fix it, I tried installing the NET framework, but it was already on my machine. Then I tried downloading ruckingenur 2 again but it still didn’t work. I also tried compatability mode…but for some reason Ruckingenur CE works?! Please tell me what is wrong!

    Leon: I’ve just uploaded a new installer that should work in x64 – the old one didn’t. You’ll need to run as Administrator if you don’t have write access to Program Files, as this game writes your save data to a file in the same directory as the game EXE.
    (I recently switched from 32-bit Windows XP to 64-bit Windows 7 and hit all the problems that everyone else hit. Whoops!)

  136. December 1, 2009 at 5:56 pm | Permalink

    Thanks a lot, loser.
    I accidentally installed your game to e:\Game, the root of my games directory. So I had to uninstall it. But your uninstaller DELETED EVERY FRIGGING THING IN THE DIRECTORY, except for some Steam files it apparently could not delete, as Steam was running. There goes my history of gaming. YOU REALLY CAN DO SOME PRETTY GOOD CODE, MAN! Now my games directory is practically empty. Thank your god I wasn’t just about to beat ADOM or I’d have ripped your guts out.
    Anyway, guess I won’t ever finish Indiana Jones and the Fate of Atlantis now. Almost finished it once, ten years ago, then got stuck, and was about to play all the way back to the point where I got stuck, but then you showed up. You really do suck.

    Hey, no problem. Perhaps I don’t tell anyone about this, so they will lose their files too. Good idea! And yes, I know of experience that many people keep their games in one directory.
    The bitching was deserved, as Zach’s irresponsibility damaged others. Had this been an application instead of a game, serious damage would have been done. (“Whine whine, who really installs all their programs under C:\Program Files anyway?”) However, the threat of violence was not serious and should be disregarded.

    Tuukka: I’m sorry that you had to be the first person to encounter this. I would suggest trying an undelete program to see if you can recover some of your save files. It looks like there’s a free one available at, although I’ve never used it before.
    Here’s the technical explanation of what happened:
    I use the NSIS installer engine to build my installers, using an installation script that I’ve had for a while (and found on the NSIS website). It turns out that the Uninstall selection is simply RMDir /r “$INSTDIR”, which would indeed cause the problem you’ve encountered.

  140. December 2, 2009 at 5:46 am | Permalink

    The files are too corrupted for the games to work anymore, but thanks for trying to help. Had I known that program exists, I might have been able to recover the games if I had used it instantly.

    Thank you for making such an excellent game! The little movie clips were cool; they really helped to build the plot. The reverse-engineering itself feels a lot like the real thing (without nearly as much complexity) and really catches the spirit of how it works and what’s involved. I only wish the game was longer. If you ever do start making games again, I suggest a longer version of this game. I would pay for more levels. πŸ™‚

    The device is currently decoding messages sent with the daily key for “today”. You need to figure out how to change the date to the date on the encoded message on the paper.
