Development studio 22 Cans will open the game up to applicants for approximately an hour each a day up until Friday.
"As we get nearer to releasing our first App Curiosity: What's inside the Cube, we are looking for some feedback. So we are asking for a few kind people to participate in trying out our first experiment.
"Hopefully these people will give honest feedback on what Curiosity is like, and spot some of the flaws in this totally unique experience. If you are interested, and you have a spare hour at about 16:00 GMT Tuesday-Friday then please apply below," reads the ad.
Curiosity: What's Inside the Cube sees every player chipping away at the same virtual cube in an attempt to discover what's inside. However, only the player who performs the final tap will be able to view its contents.
The experiment will be able to see whether the final player reveals the game's contents and how they do so. 22 Cans will monitor how news of the cube's contents spreads on social media, and use the findings in a future release.
The game will also offer users a selection of enhanced chisels as paid DLC. The cheapest costs 59p, while the most expensive is priced at £50,000.
Curiosity will be available on iOS, Android and PC next month. No release date or platforms have been announced for Cooperation at this time.
