Ludum Dare 32 — April 17th-20th, 2015 — Theme: An Unconventional Weapon

chromenopePSA: As of Chrome 42 (Released April 14th), NPAPI plugins are disabled by default! That means Unity Player, Java, and Silverlight games will not work in the Chrome browser! That said, Flash in the Chrome browser continues to work fine (PPAPI).

To Developers: Consider using HTML5 and WebGL instead. Having troubles with the export? Don’t worry. See Ports below.

To Players: A workaround is to enable NPAPI plugins in your Chrome settings. Click or Copy+Paste this URL in to a tab:


As of September 2015 however, this option will no longer be available.

Other browsers (Firefox, Internet Explorer, Safari) and Flash are unaffected, but FWIW there is no Unity Player or Silverlight for Linux.X

A strategic Bingo game you can play through in about ~10m. Please read the rules below so you know how damage works. The action key is Z or N.

I have also written up rules for playing against another person with a deck of normal cards, pencil, and paper, as well as a little on strategy:

The balance of the world has been disrupted. All is in danger, and chaos looms. It's then that one brave soul comes forth... that is you! And now, using the power of BINGO, you must save the world.

Because moving backgrounds may cause motion sickness or other problems I have provided a non-blinky version, though if you have a particular sensitivity it may be best to give it a pass.

Made using pico-8 from Lexaloffle.


- Play BINGO by taking turns with the CPU playing cards from your hand
- You both start with 15hp, and lose at 0 or less
- You have a BINGO BOARD (3x3) and a HAND of 3 cards beneath it
- Play a card from your hand to light up the square on your board or the CPU's
- Cards not on either board go in the DEAD PILE
- if the DEAD PILE fills up (5 cards), whoever played the last card takes 5 damage and a new round starts
- if someone gets a BINGO, they do 5 damage per BINGO plus 1 per card in the DEAD PILE

There are four stages, no background music and there's probably a few bugs, but basic play should work fine. Enjoy!


If the web player doesn't pop up right away, give it a second. Should work fine in FF/Chrome. If it doesn't work in those or other modern browsers please tell me.

Pico-8 is a Fantasy Console by Lexaloffle. It has a built-in editing environment and uses Lua for program code, less standard libraries. Information on Pico-8 is here:


EDIT 2015-04-21T15:54:23

I found the bugs in the original version and fixed them:

- pushing x caused an error (leftover debugging command)
- sometimes not-short games had errors (off-by-one error exhausted deck early)
- restarting did not work (tried to render stage -1, failed)

I think this is within the bounds of permitted after-time fixes so I've updated the embed URL, but just in case I'm keeping the links to the originals around.

Neat idea, didn't get the purpose of the deadpool at first but it's a nice addition. It seemed quite easy to get dealt an impossible hand, but that's the nature of the game I guess. Got quite a few index errors though, so had to refresh after each game. Neat idea, little more polish would do it well. Liked the sound, it really added to it. (Also don't press X, it doesn't seem to like it)

Is this a common variant of bingo or did you make it up? Either way I'm impressed, nice implementation or nice idea. It has the whole 'wait for your number to come up' luck, but still gives you some strategy options. Actually very fun. Pretty graphics too.

Any reason why it had to be z instead of space or something? I couldn't see the bottom bit with the instructions so spend ages trying to figure out how to press select.

Very creative, and very fun. I'm not sure if this was on purpose, but my game ended on a wonderful custom error screen (attempt to index nil on line 310 if it wasn't :P), and it left me with a smile!

@drakekin: Thanks for pointing out the errors! I'd had a pretty bad misunderstanding regarding my "take" function and it was eating half the deck, which explained all the index errors.

@Foofanoo42: Thanks! This is a bingo variant I made up for the compo. I'd been frustrated by bingo before since it's more of a slow lottery than a game and had thought up some variants, though none that worked with two players.

@Chris Delta: Thanks for playing! Was that error in the bugfixed version? I thought I'd fixed everything :/ If it wasn't the bugfixed version, what happened was it tried to restart and blew up, which is one of the things I fixed :P

This is rather unique. I like it that there can be multiple way of strategy to win the game.

Pretty neat! Most importantly, thanks for bringing Pico-8 to my knowledge. The concept of a tiny fake console is cool to say the least.

Very interesting game. It needs good tutorial and music, and it will be perfect game.

Gives 'Runtime error. Line 310: Attempt to index field '?''

Apr 23, 2015 @ 4:29am

stoarch: Was that the bugfixed version? Did it happen right at the start or after playing a bit? (That sometimes happend right at start in the original version, but shouldn't happen in the bugfix... in either case it should go away on a reload, at least temporarily)

I beat it on my first try! A lot of games would try to make bingo more interesting by adding sex, violence or characters, but this one just has tradition and good graphics. Also, the AI feels like a real person.

This is actually quite a smart game :) Like how the game is minimalist but yet still has some depth. Well done!

Once I read the rules I really enjoyed it. Well made, smart and innovative, maybe could've used a background song but otherwise I really digged it.

I love the mechanics and the graphics. It took me a little time to figure out the controls as I'm using an azerty but it was very nice to play. Great game!

Took a few goes to get into the swing of it (is there a particular strategy or is it luck based?), but enjoyed myself once I started winning :)

This is really fun! Though the only real relation to the theme was a bit of storyline fluff in the description...

yeah! I've saved the world!! \o/
Pretty cool game with nice graphics and an interesting approach of the theme. Nice entry :D

May 8, 2015 @ 6:19pm

Great little game. It's a very nice take on bingo. Until I read the comments, I thought this must be a common variant that you just pushed out there, but if you made it up, good on you. It made the whole "bingo" thing seem much less random. Also, as was mentioned above, now I've seen what this PICO-8 thing is, so I must explore it.

Quite enjoyed this fun little game, pretty tense sometimes, i liked it :D.

Nice graphics and sfx, maybe the CPU Chose sfx have a bit to much bass and made my desk tremble a bit.

Pretty nice. Pico-8 seems like a charming little thing.

One gripe though. Whenever I restart the game (refresh the page) the numbers are all the same. The random generator seed number doesn't seem to change at all.

I have no idea if changing that is out of your hands.

At first I thought it was waaay too difficult. Once I figured out how all the rules worked, I found a strategy that never lost. Finished the game! Strategy: Prioritize anything on your board, then play anything into the dead hand if it isn't full, then play anything in their board.

Visuals are neat for a bingo game i guess :D !
Pico8 stuff seems interesting btw...

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. Historically, more games are entered in the Compo, but with more people and more time, Jam games have the potential to be better (that doesn’t mean they are). Many solo participants do 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 ( 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.
