Comments and Ratings for YOU DON’T KNOW JACK

What a blast! (1.2.1)
8/17/2014 1:41:00 AM 5/5 By lsinger9404
Great game!

Glad it's back, but WTH with the interface? (1.2.1)
8/16/2014 7:57:00 AM 2/5 By aplacidlife
I'm one of those Mac YDKJ fans from way back. Still have all my jewel cases even though it won't run on any current Mac. Was so excited to see there's now an iOS version, until I tried playing. Facebook integration is one downside, but the most frustrating for me is that it's just plain not nutritive how to actually get into a game without the weird coin system and the real (not the funny ones we all love) ads mucking up the works. As far as I can tell, I have to watch a long Spanish Sprint commercial before being able to play. The Jack that I knew would know better. Please simplify and provide clearer instruction. Thanks!

Love trivia (1.2.1)

Woooo (1.2.1)

I love this app it's the best and it's fun as hell! Woo hoo Betty boo

Lost my score total! (1.2.1)
8/1/2014 3:47:00 PM 5/5 By tdm123
Enjoy playing the game for over a year, I login this morning and my score is back to zero! I have lost everything as well as when I paid for premium! I hope this can be resolved. If not just play for enjoyment but not to get to the magical 100,000,000 score and level 31. I made it to 64,000,000 and it seems my life's work is ruined! Guess I need to go get a job or something! Btw, you get to level 30 at 8,750,000, for those wondering. Update: They fixed the bug mentioned above a couple of days later and I was able to continue, now I just made 100,000,000 points to get to level 31, but there is no level 31. It just tells you, you made it to level 30 and says you won 200 points but no points are awarded and no level 31. Every game over 100,000,000 it goes through the same sequence, says you made it to level 30 and so on. Fun game, guess it is over now. Quick hint: If a game gets stuck just start your camera feature and then go back to the game and it will resume.

It's YDKJ! What's to criticize? (1.2.1)
7/29/2014 8:14:00 AM 5/5 By Michael Sibrava
YDKJ is fun, hilarious, and trivially educational. I've loved this game since I was a teenager almost decades ago, now. I still would like a pause button on the new format, but with 5 questions the world (and my wife) will have to wait.

Impossible to play (1.2.1)
7/28/2014 9:45:00 PM 1/5 By Paul Solt
I can't figure out go to even start this game. Nothing happens except for an ad for a new tmnt movie.

Fun game (1.2.1)
7/27/2014 6:56:00 PM 5/5 By Meeehty
I've loved this game for years. Wish it had an offline single player game

Waste of time (1.2.1)
7/27/2014 12:15:00 AM 1/5 By AllyK.
Can't even play the game without watching six thousand ads first. Absolute waste of time

Classic (1.2.1)
7/25/2014 2:20:00 AM 4/5 By TheDrizzle007
I had YDKJ for the PC around 15 years ago and always had fond memories, but I never thought to look for it on my iPhone! I stumbled across it the other day and tried it out, and I love it! Just as funny as the classics, and just as challenging. The game flows so smoothly, you'll almost forget you're listening to prerecorded dialogue. The one beef I have is the same complaint I have with 75% of mobile games.. I don't have a Facebook. I think Facebook is stupid.. And YDKJ requires you to have a Facebook page or else you have to play as a guest! 😪 Overall though, fantastic game. Great addition to the series.

Great game, lags a lot though. They ask a lot of stupid questions, but it's better than most games.

Don't download (1.2.1)
7/18/2014 4:05:00 AM 1/5 By Jred86L
Unless you want to watch a ton of ads, don't waste your time..

Love this game! (1.2.1)
7/12/2014 7:45:00 PM 5/5 By SexyOrangeGirl
AMAZING HILARIOUS PERFECTION!!! So glad that an iPhone version finally came out. I love how they keep the questions really current. So much fun!

Funny Fun! (1.2.1)

Really enjoyed playing as a family on the PC & later on our PS3, so great to have it on the iPad :)

I do know jack . 2 of them (1.2.1)

Since i started playing ydkj my teeth have been whiter, im staying out of prison on a regular basis and my herpes seem to be surpressed. Thanks jack

Awesome (1.2.1)
7/8/2014 2:59:00 AM 5/5 By caramela17
Very interactive game, that makes you think and feels like a game show. Love that the creators update it frequently with new questions and fun intros.

Where is everyone? (1.2.1)
7/6/2014 11:30:00 PM 3/5 By 3dsDarkDood
After a break from playing this game I came back and noticed that all the competitors are gone on guest mode. If you're going to shut down the servers at least add the abilty to play against AI. still funny

It's all fun and games... (1.2.1)
7/6/2014 10:49:00 PM 2/5 By PowerToTheSocks
...until a megalomaniac Hollywood schmuck decides to put up an ad that would freeze the game. The Planet of the Apes ad makes it impossible for me to play!!! Do they need an advertisement anyway?!

the tf2 team (1.2.1)

mann . co of ydkj spy likes it and scout likes it ydkj of jackbox games

??? (1.2.1)
6/27/2014 1:03:00 PM 1/5 By Meeseee
If you are looking out for a quick minute of fun forget this game.. On first install could never reach the game, due to advertisements, etcetera.

Too invasive (1.2.1)
6/27/2014 6:16:00 AM 1/5 By Slam Dunkz
The game requires a Facebook login (hi some people don't use Facebook ) and other interface buttons kept bringing in whole screen ads. I used to love this game on the PC back in the day. Give me a version where I can just buy episodes and play with friends and I'd keep it. I uninstalled it because for now it's just an excuse yo serve you ads.

Better than most games with Ads (1.2.1)
6/23/2014 9:08:00 AM 4/5 By RyanFromtheBlock
I liked it better when it wasn't ad-ridden, but it's still a lot of fun to play!

Ydkj (1.2.1)
6/21/2014 7:10:00 AM 5/5 By Ohhocho
As fun as it was in the 90s.

Mom game (1.2.1)
6/17/2014 8:38:00 AM 4/5 By Trgray70
It's totally a mom game and that's right up my alley. It has a bit of a slow start, but not that big of a deal. Still love it.

Too much talking (1.2.1)
6/4/2014 7:00:00 PM 2/5 By Awkwarday
I wish the host would quit trying to be funny and get to the questions. You answer a question then wait for the guy to joke around for a minute. Boring. Quit trying to access my Facebook account also. I deleted the app after about ten minutes.

Seriously needs an update (1.2.1)
6/2/2014 3:44:00 PM 3/5 By Erikaanddiego
The game is super buggy and hasn't had an update since November. Love this game but it needs an update desperately !

awful (1.2.1)
6/1/2014 10:42:00 PM 1/5 By completely_unsatisfied
takes forever to load

Great if you play on Facebook (1.2.1)

Score lowered for adds that tend to get stuck.

Fun Stuff (1.2.1)
5/29/2014 4:33:00 AM 4/5 By Curl craze
Love the game, like the app. Froze a lot so I'd prefer the computer version, but still good for on the go.

The game is great! I have been playing since the 90s. However, there is a problem with your server. I have Kindle fire and it works great. I bought an iPad and most of the time when I try to play I get a server error message. All of my other devices work great. I have really good high speed internet service it seems like your server has problems with my iPad.
