It's the latest game sweeping the App stores: Trivia Crack features a winning combination of social media, anonymity, asynchronous play, a fun, bright interface and, of course, addictive trivia. It also pushes ads, sharing scores on social media, user-generated content and limited play time with in-app purchases necessary for players to keep going or gain extra advantages -- also a winning combination, but for the publishers, not the players.

That sums up the push-pull of Trivia Crack, a game that's become viral on both Android and iOS, delighting many and infuriating others, and our pick for this week's Tap That App Tuesday.

The Basics

The most popular hit games for smartphones and tablets generally tend to have the easiest learning curve for average users. Trivia Crack is no different; the least technically savvy person you know will be up and running in minutes.

It's easy to sign up through Facebook, but to its credit, Trivia Crack gives you a hassle-free method of signing up with your email account as well. Once you're in, you get right to playing your first game -- either against friends you know or randomly assigned, variously anonymous opponents.

The gameplay is basic: answer as many questions correctly as you can in a row. Like Trivial Pursuit, questions come in categories. Trivia Crack offers Art, Entertainment, Geography, Science, and Sports trivia. Once you miss a question, your opponent has a chance to take their turn. They have up to two days to respond, so be prepared to wait for a while.

Again, like Trivial Pursuit, the game is over when one player has dominated all categories, gaining characters that represent each in the app.

Anything involving trivia, plus the sound and visual rewards for answering correctly, is addicting. Winning against opponents just adds more habit-forming reinforcement to the whole system.

The Annoying Parts 

But there are some flaws in Trivia Crack -- both by design and an unfortunate result of design -- that might frustrate you, leading to a quick uninstall before you have the chance to play more than a couple of rounds.

First, the difficulty level (or lack thereof). Trivia Crack is based on trivia questions crowd sourced from users and intended to rope in the average smartphone user. As the saying goes, you catch more flies with honey than vinegar, and Etermax (the game's publisher) knows that rewarding new users for answering questions correctly -- no matter how brain-numbingly easy they are -- is the best way to retain them.

And so the first few dozen trivia questions I was faced with as a new user were incredibly, stupidly easy. But that's not the only problem with the difficulty level. As the game progressed, I got a sense that the pool of questions might have been ratcheting up, but the difficulty level of the trivia questions remained frustratingly uneven.

In my last match (ever, probably), I was presented three questions in a row that begged the old game of "one of these things is not like the other." See if you can spot the one that doesn't belong:

"Joyce Carol Oates' Novel 'Blonde' was about which of these people?"

"Idaho is famous for which of the following foods?"

"What is the abbreviation on the periodic table for Meitnerium?"

Marilyn Monroe, potatoes, Mt. That's just one example of scatterbrain nature of Trivia Crack's difficulty settings. The user-generated questions might be free content for Etermax, but the system leads to questions that are far too esoteric and, dare I say, "trivial" -- "Which artist created the poster art for Minecraft?" Who, besides a certain small group of enthusiasts, would know or even care? -- along with questions that are too easy and some that are just badly written.

Second, the advertising, sharing and in-your-face in-app purchases. Trivia Crack has to make money, so they advertise in between correct questions, alternating those full screen ads with "share" options to help publicize the game.

Both tactics are fine and expected for free content. Everyone uses ads and wants you to help their visibility online (follow us on Twitter @LatinPostTech!). But Etermax has the timing of its splash screens down to a science, forcing you to hit the "share" button or advertisement when you're looking to continue playing.

It's a bit much, considering you actually have to pay a dollar to continue playing if you've used up too many "wrong" answers or finished too many of the allotted matches for the hour. And you will -- I had to wait for 48 minutes after a whopping 12 minutes of gameplay, because I won't pay to continue playing a game with advertisements. You can buy the "premium" ad-free version of Trivia Crack, but you'll still run into those in-app purchase-pushing walls.

The Extras + Suggestions

There is one way for a trivia fiend to continue answering questions, and it's hidden in the side (burger) menu in the appropriately named "Question Factory" section.

There, you can rate questions, suggest improvements (the "too specific" and "grammatical error" ratings are constant go-to labels) and simply answer as many trivia questions as you'd like, with no limit. It's this content creation part of Trivia Crack, plus it's social media-infused nature, that simultaneously holds so much promise and is frustratingly disregarded by Etermax.

For example, whenever you get a question in the game, a player's profile will flash on the screen, crediting them for that particular piece of content. This seems a little outlandish, but if those players were as easy to get in touch with as your opponents are through Trivia Crack's (basic but essential and awesome) social media chat and profile system, users might be able to create a culture around Trivia Crack that's more than just the game.

(Photo : Google Play) If only Trivia Crack used its profile and rewards system to foster better content, rather than only to encourage more buying.

They could set up trivia collectives, learn from each other, and Trivia Crack could become an off-hand Wiki for learning about new things, expanding users' knowledge -- like a mix of Trivial Pursuit, Words with Friends, StumbleUpon and Wikipedia. I'd certainly like to talk to whoever created the Joyce Carol Oates question and perhaps get suggestions for further reading.

In such a system, profiles could be part of a larger game in Trivia Crack -- a game of expanding and demonstrating your trivia mastery through creating and improving content, and players could be rewarded by both Trivia Crack's publicity machine highlighting their profile, and Etermax essentially gamifying the whole creative process behind Trivia Crack, in the "Question Factory" feature. 

But there's no gaming aspect to it, no rewards, no opponents and no connection or incentive built into the backend of Trivia Crack. In fact, "Question Factory" feature comes off to experienced eyes as no more than "work at Etermax's content farm for free."

Even without making the trivia creation and improvement system into a big social gamified knowledge factory, the "Question Factory" could at least do above-average users the favor of incentivizing their improving the game's content by offering rewards.

More time, more bonuses, more in-game currency or "lives" -- or whatever Trivia Crack wants you to purchase in order to continue playing the game for more than 10 minutes every hour -- would at least show some respect towards the trivia masters in the audience who keep the whole system going with their volunteered input, and such a system would help fix Trivia Crack's aforementioned content problems.

But there are no incentives: It's clear Trivia Crack just wants users to buy more stuff. It isn't particularly interested in using real crowdsourcing tools to improve the quality of its content.

Tap That App?

Frustration with Trivia Crack's inconsistencies and clear cash-grab priorities aside, the app is fun, entertaining, and you might learn a thing or two. At least enough to merit giving it a download and a try.

However, when you hit the in-app purchase wall after a few rounds, just think about how much another 15 minutes of gameplay in the next hour is really worth, before considering going to the game's in-app store.

Maybe, instead, spend some truly "free" time beefing up your trivia bonefides by cruising an app like Wikipedia after your 10 to 15 free minutes of Trivia Crack inevitably ends.

Trivia Crack is available on iOS and Android
