BUFF founders wanted to create a gaming loyalty platform that would reward users simply for playing. So, we start with building a complex desktop app that could handle high loads and was fraud-secure.
As the platform grew, got its first investments, and became popular with millions of users worldwide, we went for a mobile application as well. Recently, we’ve run a massive UI/UX revamp of the platform to make it more consistent and user-fit while adding new crucial functionality.
For BUFF, we had to build a complex desktop application, more like a universal support system for all types of games that are supported by Owervolf. The app had to be secure enough to avoid cheating and verification fraud, while also having the capacity to manage lots of users at the same time. So, our goals were:
As BUFF evolved, its founders decided to create a mobile application with functionality identical to a desktop platform. So, in just 3 months, we had to:
Over time, BUFF’s design system started to lack consistency and grew outdated with overloaded screens and complicated UX. We also had to add some new social media features. So, during the redesign, we needed to:
The team managed to build a cross-platform loyalty program that enables gamers to earn coins in the background as they continue to play without interruption. Inside BUFF, there are:
We provided quick sign-up via e-mail, Google, or Discord. So that users can create & manage their own personal profiles.
We’ve created a smooth & engaging onboarding flow with educative pop-ups to help users get acquainted with the platform.
BUFF supports some of the most popular games so that users can play their favorite ones – like CS:GO, Fortnite, League of Legends – right in the app.
The platform has a complex system of daily tasks and challenges for its users to get weekly bonuses, rewards, and, finally, make in-app purchases.
BUFF live economy is provided by the AI- algorithm & based on real-time analysis of user’s performance – the best players earn the most coins.
Users can track the history of games played and access advanced stats to review performance, and earnings, compare averages with other users, etc.
The platform has its own in-platform marketplace with native currency – BUFFs – which can be redeemed for real-life Items. Later, during a redesign, new categories, tags, & more features were added.
From a technical perspective, we managed to build not just one React app but a system of applications working in synergy and communicating via the EventBus pattern. As a highly-scalable & secure solution, BUFF has lots of tech perks hidden inside:
achieved due to database optimization, autoscaling, and scalable microservices architecture
developed to integrate Steam items into BUFF so that users could get them as rewards
that prevents the use of any malicious properties, bot creation, or background mining & verifies users
BUFF passed rigorous tests of security and authenticity to partner with Overwolf
the team provided extra encryption for any transactions happening on the platform when users buy desired items
We’ve worked through open APIs to connect users’ PlayStation ID to their Buff accounts
we elaborated a system that collects data from advertisers, analyzes it and builds ad indices accordingly
In just 2 months, Fulcrum designers ran a complete overhaul of the platform – we elaborated a consistent design system, switched to a template design, updated the app’s UX, and added new features to drive social networking:
We’ve adjusted the new branding created by an external agency to web design basics and made BUFF’s interface consistent across all platforms
The team developed a custom unified dictionary for consistent communication with users
Fulcrum designers remastered the platform UX-wise & incorporated outcomes of the earlier conducted UX research
It allowed us to switch to a template design & unload designers, allowing the business team to work more efficiently:
It allows users to record, edit, post, comment, & share moments from their plays.
We’ve adapted the Premium subscription page to a new design system & made it user-friendly.
It’s a functionality – BUFF’s “battle pass” – that rewards gamers for time spent online.
