LTS QA

Overview

Game Genre

Gacha Turn-based RPG based on a famous South Korean Webtoon/Manhwa

Core Technology

Strategic team-building, elemental counters, and special character abilities (“Charyeok”)

Platforms

Published by Indonesia’s leading media group, targeting the Indonesian and wider Southeast Asian (SEA) mobile market.

Challenges & Solutions

Challenge 1: The “Legacy” Codebase Factor

The Problem:

The original game has been live globally for over a decade. Its source code contains 10 years of layered updates, making it highly likely that a newly localized version for Indonesia would inherit old technical debt, performance issues, or hidden legacy bugs.

Our Solution:

We conducted a deep Code & Feature Regression Sweep, prioritizing the core gameplay loop and oldest system modules to catch hidden bugs early.
We ran intensive long-session stability tests to monitor memory leaks, ensuring the older architecture runs smoothly on modern mobile OS versions.

Challenge 2: Market Suitability for Modern SEA Gamers

The Problem:

A game that succeeded globally 10 years ago might not appeal to modern Indonesian and SEA mobile players. The publisher needed real data on whether the progression speed, gacha drop rates, and difficulty curves would still resonate with today’s market.

Our Solution:

We formed a dedicated Playtest Focus Group consisting of experienced QA players who specialize in modern anime/manga gacha games in the SEA region.
Beside standard functional testing, our team playtested competing top-tier gacha games currently active in the market. We delivered a comprehensive Competitive Benchmark Report to the publisher, providing detailed feedback on what the game does well and actionable advice on adjusting drop rates, reward systems, and difficulty curves to improve player retention

Challenge 3: Extreme Sprint Timeline

The Problem:

The publisher required five specialized types of QA (Functional, LQA, Compatibility, Regression, and Market Playtesting) to be completely finished in under three weeks, which demanded an incredibly high level of efficiency.

Our Solution:

We used a Dynamic Resource Allocation strategy, splitting the QA team into concurrent sub-teams that worked in parallel.
While the functional team verified system logic, the LQA and Playtest teams worked simultaneously inside optimized test environments, allowing us to deliver all five testing phases successfully before the strict 3-week deadline

Overview

Game Genre

High-volatility, Reel Video Slot (iGaming)

Core Technology

Complex mathematical models blended with high-fidelity visual and particle effects.

Platforms

Mobile Web Browsers and Lower-End Devices.

Challenges & Solutions

Challenge 1: Complex Feature Interaction Logic

The Problem:

The game features three unique “Special Wild” characters that can appear and interact at the exact same time. Because each character triggers different multipliers and behaviors, it was highly critical to make sure these symbols did not cause math errors or game crashes (“logic collisions”) when they showed up together.

Our Solution:

We mapped out an Interaction Logic Matrix to document every possible combination of the three special characters appearing on the reels at once.
We used special backend test tools to force specific reel results. This allowed us to instantly test these rare character combinations over and over, verifying that the multipliers calculated perfectly every single time.

Challenge 2: Regulatory Risks with the “Buy Feature”

The Problem:

The game has a “Buy Free Spins” mechanic, which is under strict monitoring by gambling regulators. Any mistake in the cost-to-payout ratio (how much it costs to buy vs. how much it pays out) could cause immediate loss of the gaming license or massive financial damage.

Our Solution:

We ran High-Volume Simulation Testing (Parallel Automation Testing) to execute millions of spins through the “Buy Feature” system.
We checked the resulting payout data against the client’s target mathematical model to ensure the theoretical Return to Player (RTP) matched the actual gameplay exactly, ensuring 100% regulatory compliance.

Challenge 3: Performance & Animation Stability on Mobile Browsers

The Problem:

The game uses heavy steampunk animations and special particle effects. The big challenge was keeping the game running smoothly (maintaining a high frame rate) across many different mobile web browsers and older, cheap smartphones without lagging or overheating.

Our Solution:

We set up a Cross-Browser Testing Matrix, testing the game across popular mobile browsers (Safari, Chrome, Samsung Internet, Android Webview) on various low-end devices.
We monitored memory usage, battery consumption, and frame rates during long-session tests. When we found drops in performance, we worked with the developers to optimize asset loading and web-rendering sizes.

Scope of Work

• Functional test for all the game features
• Non-functional tests for currencies and languages
• Compatibility test for Android and IOS operating systems on 32 different mobile device types
• Cloud Mobile Testing to increase device types tested

Challenges & Solutions

Challenge 1: Proprietary Tooling & Language Barriers

The Problem:

The client used their own custom tools and test data setups, which were written completely in their native language. This made it very hard for our international team to set up the test environment and manage data, slowing down our start.

Our Solution:

We formed a special group of “Bridge QA” members who spoke both languages. They translated the tool interfaces and wrote easy, step-by-step guides to train the rest of the team.
We worked closely with the developers and used real-time screen translation tools so our team could learn the tools quickly without wasting time

Challenge 2: Extreme Hardware Fragmentation & Cross-Play Sync

The Problem:

The title demanded seamless, optimized performance across an immense hardware spectrum – ranging from high-end gaming PCs to budget smartphones. The core technical challenge lay in ensuring 100% real-time data synchronization between these vastly different platforms within a massive open world.

Our Solution:

Implemented a rigorous Device Compatibility Matrix, categorizing a massive device pool into distinct tiers based on SoC (Chipsets), RAM, and OS versions for both iOS and Android.
Designed advanced Cross-Play & Network Latency Simulation test scenarios (e.g., simulating packet loss, high ping, and seamless switching from Wi-Fi to 4G/5G) to strictly validate data synchronization of player positions, inventory states, and world interactions.

Challenge 3: Linguistic & UI Complexity (LQA)

The Problem:

Launching the game in many regions with many languages at once meant a high risk of text breaking or overlapping on the screen, words being translated out of context, or using terms that might offend local players.

Our Solution:

Pioneered a hybrid approach combining Semi-Automated LQA with Manual Verification. We developed internal scripts to capture bulk screenshots during dialogue flows, allowing rapid automated scanning for UI overlapping and text clipping.
Utilized Native-Speaking Linguistic Specialists to conduct deep contextual reviews, ensuring that survival-specific
terminology (crafting systems, items, lore) felt natural, consistent, and culturally respectful to local players.

Challenge 4: Massive Content Scope vs. Market Timing

The Problem:

The game world was huge, and there were too many stories and missions to test. Because the global release date was strict, we had a massive amount of things to check in a very short amount of time.

Our Solution:

We used a Risk-Based Strategy. We prioritized testing the most important parts first: the main gameplay, the cash shop/payment systems, and the main story missions.
We used Parallel Testing (Simultaneous Execution). Instead of testing one by one, we divided the massive map and
test cases into smaller, independent sections. Multiple QA sub-teams tested different parts of the game at the exact
same time using different test environments. This multiplied our testing speed and allowed us to cover the entire game within the strict deadline.
