Phreak36

by socks - Jam Entry

** THIS GAME REQUIRES A MICROPHONE TO PLAY **

...or other functional audio input device
If the default device does not work, you may need to change the input device with V before attempting to play.

Phreak36 is a game about phreaking, and getting long-distance telephone calls for free. The goal is to produce a sustained tone at 2600 Hz. The keypad does not work, sorry. :(

You can read more at https://en.wikipedia.org/wiki/Phreaking



CONTROLS:
v = Change input device
z/page down = Lower goal frequency
x/page up = Raise goal frequency



Most people (almost everyone) will be unlikely to hit 2600 Hz. Try lowering the goal to ~1600 for a comfortable whistle.

nerds: If you happen to try a blue box or similar out on this, let me know the results (I don't expect it to be good). I understand this is not an authentic representation.


I planned to have a moodier setting, with drizzling rain, an actual background, functioning phone numbers, and maybe some music... but between ambition and excessive relaxation that didn't happen.
I appreciate the feedback. Thanks for playing!

Good idea ! I didn't have any problems with the microphone. I seemed to be very dumb while playing your game :'). Graphics are simple and effective. I like the concept of using our voice in a game. This was surely an awesome challenge for you. It was impossible for me to produce a sustained tone at 2600 Hz, I lower the goal to 1600 as you adviced ;) Keep creating games !

Great idea! After a bit of practice I got to 2600. I woke up my wife trying to get to 4khz, but never got it to be stable. One feature it definitely needs a way to get restart after you get the free call.

I've never tried anything like this, finally got a "FREE CALL" by whistling hard. :D

Is there anything else after that?

Nice idea. It was funny to play with the echo it creates on my machine. I tried to whistle, but 1700 was the max I reached.

So...
beep -f 2600
:p

Mini Submission FAQ

TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

CAN I ENTER BOTH EVENTS?: You should pick 1 event, whichever you think it’ll do better in. If the idea is strong, and everything plays well enough, you can go Compo. If you’re a perfectionist, and would prefer people to play a more polished game, do the Jam. Many solo participants enter the Jam.

If you made 2 games, unfortunately, the website doesn’t support multiple submissions per user. To submit your 2nd game, you will have to make a 2nd account. Only do this if you made 2 games. Alternatively, if one game is better than the other, then consider just entering the better game.

CAN I KEEP WORKING UNTIL THE DEADLINE?: Yes! Immediately after the 48 or 72 hours, we do something called Submission Hour. As the name suggests, it’s an extra hour for you to package, upload, and submit your games. If there were catastrophic issues trying submitting your game, or you misunderstood how submissions work, that’s okay. It happens. We’re flexible. If you need advice, check with the folks on IRC. If you need an admin, get in touch.

CAN I KEEP WORKING ON MY GAME?: Oh definitely! You should! But for the sake of judging, keep the Compo or Jam version around. You can include a link to the Post-Compo/Post-Jam version of your game on your games page, but sure your main links are the original version.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate at least 20 games to improve your visibility (Coolness).

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crashes, win condition, or tiny bugs after the deadline. In a sense, this is like “porting” to support more players. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just fixing mistakes you should have caught had you been better rested.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs (http://mysite.com/mygame.zip) and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.
