Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Turing Tumble VR is fully playable right now, and promises numerous hours of play. So we wanted to propose it to the community at this point, to both offer some fun to the players and get as many feedbacks as possible to help us decide where to put our energy and time for future improvements and additions. TTVR is by nature a matrix allowing pretty unlimited uses and possible games : we thought better to enrole the community in choosing where to go in this maze of possibilities at the earliest possible stage.”

Approximately how long will this game be in Early Access?

“9 months to a year. Some features are under development already, just not polished enough to be released right now, but they will appear in Q4 2018. Some others are planed but will take a little longer to implement. And we need time enough to let community feedbacks draw consitent development axes.”

How is the full version planned to differ from the Early Access version?

“The main feature we want to add is an in-game puzzle editor that allows to turn a machine you invented into a challenge you can propose to all TTVR players without removing your Head Mounted Display. With all the network functionalities allowing to upload your puzzles, dowloads other's and rate their difficulty. This one is our absolute priority.
We're also working on other game modes, more centered on speed and reflexes, and also competitive game modes that could be played by 2 to 10 connected players.
Of course community feedback will be crucial to shape those new game modes. Your suggestions are more than welcome !”

What is the current state of the Early Access version?

“This early acces release offers :
- All tutorials needed to understand both gameplay, controllers use and the mechanic of each component of the game.
- Save slots management, so that many players can play the game on the same computer and save their progression at their own pace.
- Puzzle mode offering 59 challenges that will take hours to solve. Actually dozens of hours if your IQ is below 300.
- Features unlocked as long as you progress in the puzzle mode.
- Free play mode that allows a theorical zillion of machines to be invented and used at will. You can also save and reload any machine you've build in the game.”

Will the game be priced differently during and after Early Access?

“Depending on the amount of time that will be spent on bringing TTVR from early access to final release, we will raise the price a bit. Right now a 25 to 33 % raise is envisaged.”

How are you planning on involving the Community in your development process?

“Let's be clear : llistening to community is the key to make great games in our opinion. So constructive comments are welcome, destructive comments will be listened carefully, and as soon as the early access version is live, feedbacks from you guys become the main input in our development process !”

About This Game

Turing Tumble is a mechanical computer driven by marbles. Invented by Prof. Paul Boswell, who used to teach at the University of Minnesota, this great idea is designed to expose what's hidden in the silicon core of microprocessors, making it possible to witness at a big scale and slow pace what electrons do a billion times each second in the micrometric junctions of a computer chip.

Playing with it, you'll understand all the underlying basis of computer programming, how just connecting switches in clever ways can do amazingly smart things, and above all, you'll see it happen, and will get a feel of it.

What do you mean by mechanical computer?

Turing Tumble materially consists in a board, blue and red marbles, and 6 types of mechanical parts you can add onto the board to build computing machines. The set of parts is Turing complete, which means that Turing Tumble can do anything a computer can do - or at least it could if the board were big enough. But even at it actual size, it already allows to add, divide, exponentiate, compare, count, do logic, produce patterns and a lot more.

Recreated in VR, the board is as big as a small building, and 59 challenges have been implemented for the puzzle mode. Solving them will make you recreate nearly all the functions of a microprocessor, and don't be fooled by the first ones : they start easy but become soon enough quite difficult and then extremely challenging. Last ones will be tough even for an expert programmer.

Can I play if I know NOTHING about computer engineering?

Sure! Puzzles become challenging as you progress, but the game can be played from the age of 8, and gives a strong notion of what computers and code are about to young kids, without having to previously teach them about complicated mathematical concepts. From experiencing with the actual game, kids 8-12 manage to solve the 20 to 30 first puzzles. Adults get addicted by puzzle 27, and their brain melt steadily after puzzle 35. Younger kids enjoy the first 10 challenges and building their own computers.
In short : if you learn something it will be by playing, there's nothing you have to know beforehand.

What kind of life expectancy has this game?

Definitely not a 10 minutes experience, TuringTumbleVR is already a dozens of hours long game if you only want to puzzle every challenge out. And note that there is no answer written anywhere : for each puzzle, any machine you build that produces the required behavior will be validated. Developing and testing the game, I found myself replaying already solved challenges for the sake of inventing a more beautiful or elegant solution!

As you'll make your way through puzzles, you'll unlock additional features to be used in both puzzle mode and free play, offering you even more possibilities.

As of free playing, you can invent and run millions of machines. Your creativity and willingness to implement more and more complex functions are the only measurable limit.

Please also keep in mind this is an Early Access release, and that, for entertaining and/or fun and/or challenging they are, the 59 puzzles provided are only the 59 first puzzles.

You're the next step!

Please give us feedbacks through the community page : further development are already on the making, but from now the future of TTVR is mainly what you'll shape it! Share your experience and suggestions!

Experiment, be creative, learn and above all have fun with TTVR!
