Update on The Vortex for Google Assistant

Recently, we announced that we will be discontinuing The Vortex on Google Assistant, but that it would be possible to transfer your game state over to Amazon Alexa for anyone who wanted to do so.

It’s rewarding to see how many players from around the globe enjoy and intend to continue playing The Vortex! In order to give people more time to transfer their game, we will delay The Vortex’s discontinuation on Google Assistant until August 31st.

Visit our support page, and send us the following data:

  • your unique name;

  • ship integrity;

  • amount of multi-gel;

  • memories of the past;

  • and other inventory (tools, etc.)

On both platforms. Once we have that data, we can start the transfer.

Here’s an example:

Google Assistant
Name: Jaime
Ship integrity: 64%
Multi-gel: 57
Memories of the Past: 99%
Tools: alpha has a level 2 repair tool, beta has a level 1 strong arms tool, and gamma has a level 2 temporal tool

Amazon Alexa
Name: Jaime
Ship integrity: 53%
Multi-gel: 16
Memories of the Past: 10%
Tools: beta has a level 1 repair tool and alpha has a level 1 laser tool

End of Service Announcement for The 3% Challenge

Thank you, Candidate.

You’ve been a great help to us all. You’ve gone above and beyond all expectations and overcame every challenge. You’ve been with us through thick and thin; you’ve competed in the global competition, shuffled through the maze's unruly waters, freed yourself from the cell, and went through the Winter Challenge. You’ve played every ending. You’re still in the top 3%.

You have ultimately earned your place in the Offshore; therefore, the “Process” is no longer necessary.

Therefore, we’re discontinuing The 3% Challenge on August 12th, 2022.  

As thanks for sticking with the game, we’re offering you every chapter of the game for free until Aug 12, 2022 so you can enjoy it until that date. It will not be possible to purchase any chapter as of today.

On October 8th, 2019, we launched the game with the help of talented people. Thank you, Netflix and Rio Games, for your work and dedication to the project, and thank you to everyone on The 3% Challenge team. We’d also like to thank the Google Assistant and Amazon Alexa teams and our supporters and investors for helping make this happen.

While this is the final stretch for this game, we’re building new and interesting things that we hope will excite you just as much.  

Once again: Thank you, Candidate.


Obrigado, Candidato.

Você tem sido uma grande ajuda para todos nós. Você superou todas as expectativas e superou todos os desafios. Você esteve conosco nos bons e maus momentos; você competiu na competição global, atravessou as águas turbulentas do labirinto, se libertou da cela e passou pelo Winter Challenge. Você jogou todos os finais. Você ainda está entre os 3% melhores.

Você finalmente conquistou seu lugar no Offshore; portanto, o “Processo” não é mais necessário.

Portanto, descontinuamos o Desafio 3% a 12 de agosto de 2022.

Como agradecimento por continuar com o jogo, oferecemos todos os capítulos do jogo gratuitamente até 12 de agosto de 2022 para que você possa aproveitá-lo até essa data. Não será possível adquirir nenhum capítulo a partir de hoje.

Em 8 de outubro de 2019, lançamos o jogo com a ajuda de pessoas talentosas. Obrigado, Netflix e Rio Games, por seu trabalho e dedicação ao projeto, e obrigado a todos da equipe The 3% Challenge. Também gostaríamos de agradecer às equipes do Google Assistente e Amazon Alexa e nossos apoiantes e investidores por ajudar a tornar esse projeto real.

Embora este seja o trecho final para o jogo, estamos construindo coisas novas e interessantes que esperamos que o empolguem muito.

Mais uma vez: Obrigado, Candidato.

End of Service Announcement for The Vortex on Google Assistant

Interplanetary explorers,

We highly appreciate your excitement and involvement with The Vortex. It is motivating to see you love this game as much as we loved to create it!

Google announced it will shut down its Conversational Actions platform next year, which will preclude the normal functionality of the game.

For this reason we’ve decided to discontinue The Vortex for Google Assistant on August 12, 2022. [We have delayed this date to August 31.]

For Amazon Alexa players, no changes apply as we will continue to operate The Vortex on that platform as usual.

For Google Assistant players who wish to continue their journey after the end of service, we can help transfer your game to Alexa. Just get in touch with us on our Support page.

Thank you for all of your support over the years, and stay tuned for exciting new updates from us in the future!


Exploradores interplanetários,

Apreciamos imenso seu entusiasmo e envolvimento com O Vortex. É motivador ver que você ama este jogo tanto quanto nós amamos criá-lo!

O Google anunciou que encerrará sua plataforma Conversational Actions no próximo ano, o que impedirá a funcionalidade normal do jogo.

Por esse motivo, decidimos descontinuar O Vortex para o Google Assistente em 12 de agosto de 2022. [Adiamos esta data para 31 de agosto.]

Para os jogadores do Amazon Alexa, nenhuma alteração se aplica, pois continuaremos operando O Vortex nessa plataforma normalmente.

Para jogadores do Google Assistente que desejam continuar sua jornada após o término do serviço, podemos ajudar a transferir seu jogo para o Alexa. Basta entrar em contato conosco em nossa página de suporte.

Obrigado por todo o seu apoio ao longo dos anos e fique atento para novas atualizações interessantes no futuro!

End of Service Announcement for Voice Quest

Dear Magicians,

You completed the Quest with imagination and flair. You’ve successfully saved King Arthur and grew up to be Merlin’s most likely successor.

Naturally, all adventures have a beginning and an end. Google announced it will shut down its Conversational Actions platform next year, which will preclude the normal functionality of the game.

For this reason we’ve decided to discontinue Voice Quest on August 12, 2022.

Thank you for playing and inspiring us to keep moving forward.

We’d also like to thank Google Assistant’s team for always working closely with us and our marvelous Voice Quest team.

Although this means farewell for now, we will have some cool things coming up in the future. Stay tuned!

Doppio at Alexa Live 2020

Amazon announced a slew of new and exciting features for the Alexa platform yesterday as part of Alexa Live, an all-online streaming developer conference. At Doppio, we’re really bullish about the future of the Alexa platform for games, and so we were thrilled to be a part of several of the event’s announcements.

Here’s a quick roundup on all things Doppio from the Alexa Live program!

The Web API for Games lets us take our games to the next level

The Web API for Games is an exciting leap forward for our ability to deliver voice-forward games that also have great visual experiences. It enables developers like us to build rich animations on the back of web-standard technologies; to provide more a more dynamic audio experience with background tracks, loops and effects; and to take greater control of the player’s experience by controlling how and when the device prompts for voice input. 

Back in April, we updated The 3% Challenge with a refreshed visual experience built on top of this exciting new technology, and we think it was a great improvement. You can try it out now on any Echo Show or Fire TV Cube device.

However, that’s not the most exciting thing we’re doing with the Web API for Games…

We’re bringing PAC-MAN to Alexa!

Yeah, you heard that right! As Jeferson announced during the conference, we’re working on a new game that will bring a voice-controlled PAC-MAN experience to your Alexa devices

We’re really excited about this new game and we can’t wait to share more about it with you soon. To be the first to hear more, you can sign up for our newsletter – you definitely won’t want to miss out on this one!

Using APL-A to upgrade the audio experience on The Vortex

APL-A is an exciting new platform feature that allows developers to do more advanced audio mixing in our skills’ audio experiences. All of this happens at runtime, meaning we don’t need to spend a lot of time in development tweaking every audio clip by hand. And, it’s done in a simple and straightforward way that doesn’t slow down the player’s experience with our games.

João Costa, our Sound Designer, spoke about our experience converting The Vortex’s audio content to APL-A. You can also try it out for yourself in the game right now!

Quick Links allow you to launch directly into our games from a link

The new Quick Links feature provides a way for you to launch directly into our games from a link on the web. As our Marketing Lead Carolina Rocha discussed during the conference, this provides a quick and easy way for you to try out new games on this exciting platform; now, instead of having to remember an invocation phrase, you can just click a link and send the skill directly to the device of your choice. 

In fact, you may have already seen these links throughout this post! But if not, here’s one for The 3% Challenge and one for The Vortex – try them out now!


That’s all for now! Stay tuned for more news about all these updates in the coming weeks!

Happy Birthday, Doppio!

Happy Birthday, Doppio!

Two years in, we’ve been fortunate to have some success with our first two titles, The Vortex and The 3% Challenge, both of which approach the challenge of designing fun and engaging voice games from slightly different angles.

I wouldn’t say, however, that we’ve found the “perfect formula” for success here yet. We believe that just falling into complacency with existing design patterns and limiting oneself to just building more of the same sort of games that already exist would be a terrible mistake to make in this space right now.

The Vortex is now available in Portuguese and Spanish!

Our first game, The Vortex, has received an important update. The game is now available in 2 new languages: Portuguese and Spanish! You can now play through the entire storyline and access all the content in either English, Portuguese or Spanish. The update is currently available for Amazon Alexa. Support for Google Assistant will follow soon.

Do you have any friends who speak Portuguese or Spanish? Be sure to let them know and also tell us what you think about the update!


Acabamos de fazer uma atualização importante no nosso primeiro jogo, The Vortex. Agora ele também pode ser jogado em Português (“Alexa, abra o Vortex”) e Espanhol (“Alexa, abre el vortex”) além da versão em Inglês original.

Esta atualização está disponível agora para a Alexa, e em breve também estará disponível no Google Assistente (“OK google, fale com o vortex” / “ok google, habla con el vortex”).

Espalhe a notícia para os seus amigos que falam Português e Espanhol, e compartilhe conosco o que achou destas novas versões!


Hicimos una actualización importante en nuestro primer juego, The Vortex. Ahora también se puede jugar en Español (“Alexa, abre el

Esta actualización ya está disponible para Amazon Alexa, y pronto estará también disponible en Google Assistent (“ok google, habla con el vortex” / “ok

The Vortex Highlighted in Amazon's Alexa Developer Spotlight

Jennifer King from Amazon published a new interview with us today on the Alexa Blog’s developer spotlight.

We discussed how we set about to make The Vortex, why we’re so excited to be working on voice-first games, and how we use in-skill purchasing to provide a premium experience for our players who want to experience all of the game’s story faster.

Give it a read today!

The Vortex is now available on Google Assistant!

We’re very excited to announce that The Vortex, Doppio’s debut, voice-first space adventure game, is available today to play on the Google Assistant!

You can play the game as a completely voice-driven, audio-only experience on smart speakers like Google Home, or pair it with a fully-interactive visual experience when you play on smart displays like the Google Home Hub. You can even play on Android phones and tablets, or on iOS devices with the Google Assistant app installed. With all of these new devices at your disposal, it’s easier than ever to jump into the game, build your robotic team, and explore the mysteries of The Vortex!

Just click this link to get started! (Tip: tap the link on your phone and you should be launched right into the Google Assistant app, if you’ve got it installed!)

This marks our first game for the Google Assistant, and we’re thrilled for all of you to try It out! Once you’ve played the game, feel free to send us any feedback you’ve got. And, as always, if you enjoy The Vortex, please leave us a review!

Happy February everyone!
