Before OnePlus launches, its next flagship, the OnePlus 6T, the company will kick off a puzzle game competition that has a grand prize worth $30,000. Called Crackables, the game is played online on mobile devices only and represents a partnership between Google and OnePlus.

You don’t need to install any apps, and you don’t need to buy a OnePlus phone to enter the competition. All you need to do is to point your mobile device to this link at 8pm today (GMT +8) and try to solve the game as fast as possible.

The puzzle has six parts, arranged as the sides of a cube. You need to be among the first 1,000 to solve three parts to qualify for the main event. which involves having OnePlus send a microcontroller to them. Then you’ll have to beat the other 999 players to grab the $30,000 ultimate gaming setup prize. If you place second or third, there will be “mysterious prizes”.

We have no idea what to expect from Crackables. Apparently, the object of the game is to help someone escape. OnePlus describes it as a series of “Android-based crypto-puzzles” made for “tech-savvy users.” Sleep Deprivation Lab wrote the whole thing, and the puzzles need a combination of skill and speed to complete, as the puzzles are both digital and physical. The head writer of the challenge was Davidson Cole, who has worked on Shadowrun, F.E.A.R. and Eclipse Phase. We have no idea what that means other than that you’ll have to use a mobile phone to win the game.

OnePlus also worked closely with the APAC division of the Google Zoo team to develop Crackables. Your best bet, of course, is to tune in on Tuesday morning and try to beat the puzzles as fast as you can.
