Game development

Negro Blanco Software builds games for iPhone, Android and the browser: real-time multiplayer games, demos playable in the browser and sites that promote the game. Game design, the app, the server and store release are handled by one person; the trivia game Trivium Arena, now being prepared for store release, was made this way. You talk directly to the person who writes the code.

What we do

  • iPhone and Android games: as in Trivium Arena, both platforms come from one codebase (React Native); new features arrive on both at the same time.
  • Real-time multiplayer: automatic matchmaking and private games opened with a room code for friends. Question order, timing and scoring are calculated on the server; a player who loses connection can return to the match where they left off. In games that match you with strangers, chat can be limited to ready-made phrases instead of free text.
  • A demo or web game playable in the browser: a short version that can be tried without downloading, or a game played directly in the browser.
  • Rankings and daily challenges: trophies, experience points and rankings; a daily challenge in which everyone plays the same questions or the same level under the same rules.
  • In-app purchases and store release: in-app purchase setup if needed; App Store and Google Play pages, screenshots and the review process.
  • A game landing site and a "notify me" list: a site that explains the game before it is released and collects the email addresses of interested people.

Who it is for

  • People who want to release their own game: individuals and teams with an idea who are looking for someone to take on the app, the server and the release.
  • Companies that want a promotional game for their brand: a short game or trivia quiz played in the browser or on the phone.
  • People who want to run in-house training and quiz competitions: contests that employees join from their phones with a room code.
  • People who want to gauge interest before releasing a game in the stores: you can start with a short demo playable in the browser and a "notify me" list.

For apps other than games, see mobile app development.

How we work

  1. Idea and rules: together we write down who the game is for, how long one game lasts, and the winning and scoring rules.
  2. Playable draft: before the graphics are finished, a plain version is prepared and played to see whether the rules work.
  3. Development and testing: you install the test build on your own phone (TestFlight on iPhone, a Google Play test track on Android); the multiplayer parts are tested on several devices at the same time.
  4. Release and after: store pages, review and launch; then bug fixes, new content and server monitoring.

What sets the price

  • Whether it is single-player or real-time multiplayer.
  • The amount of content: the number of questions, stages or levels, and who provides the content.
  • Who provides the graphics and animations.
  • The number of platforms: iPhone, Android, browser.
  • Server needs and maintenance after launch.

Store account fees (Apple's and Google's own fees) are separate from the development fee, and the accounts are opened in your name. The quote is free; we send the scope, timeline and price in writing within 2 business days.

Example project

Trivium Arena

A real-time trivia game where 1–4 players answer the same question at the same time: Arena with automatic matchmaking, one-on-one Duel, Private Game with a room code, and Daily Quiz, where everyone gets the same questions. Questions are in 6 categories; an Arena match is 10 questions and takes about 4 minutes. iPhone and Android come from one codebase (React Native); on the server side there is a Postgres database and real-time channels. The game is being prepared for store release; a short demo is playable in the browser.

FAQ

How is cheating prevented in a multiplayer game?

Every part of the game that has to be fair runs on the server: question order, timing and scoring are calculated there. The correct answer is kept on the server and is not sent to the phone until the moment it is revealed; so even someone poking around inside the app cannot see the answer in advance. Answer time is also measured on the server, not on the phone.

Do you make the graphics yourselves?

The interface and game design are ours. If custom character art, illustration or animation is needed, we decide together in the quote who provides it and how much is needed; if you already have artwork, we use it.

Can a demo be made that is played in the browser?

Yes. As on triviumarena.com, a short version that can be played without downloading can be added to a landing site. That way people curious about the game can try it before going to the store.

Can players play without signing up?

If you want, yes. In Trivium Arena you can start playing as a guest on first launch; those who want to sign in later do so with an email or Google account. So there is no form to fill in between downloading the game and the first match.

Who uploads the game to the store?

We do, using your developer account. The App Store and Google Play accounts are opened in your name; we handle the store page text, screenshots and the review process.
