✨ [Case Study] Achieving ROAS 358% with a Strategy That Activated RPG Users’ Cooperation and Competitive Spirit

RPG players tend to respond to cooperative systems
—where they achieve goals together—and competitive systems,
where they compare personal achievements and growth.
Playio crafted an operational strategy aligned with
these genre characteristics naturally increase user activity.
As a result, our Raising the Spirit King campaign
achieved an impressive ROAS of 358% in Japan.
🎮 Client Introduction
Eight Studio is a Korean developer known for various idle RPG titles.
<Spirit King Quest> is an idle RPG with a strong auto-battle progression loop and rich collection elements.
In this Korea/Japan/Taiwan campaign, we focused on two main objectives:
Increasing installs + boosting ROAS,
and designed Playio-exclusive strategies that stimulate user cooperation and competition.
🔧 Playio Strategy: Designing Natural Triggers for Cooperation & Competition
1) Time Quests & Hidden Quests — Helping Users Adapt to the Growth Loop
These quests are designed to keep players engaged in the early phase long enough to grasp the game’s core growth structure, such as leveling and advancement.
This helped users quickly adapt to the main loops and strengthened repeat logins.
2) Community Events — Creating Opportunities to Showcase Achievements
We built a flow where users actively share their growth and accomplishments with others. This naturally increased their attachment to the game and strengthened long-term engagement.
3) Playio Dungeon — A Shared Goal That Quickly Boosts User Activity
Playio Dungeon encourages multiple users to work together toward a shared objective. This cooperation effectively drove installs, accelerated entry into core content, and increased quest completion rates in a short period.
📊 Campaign Results
| Region | D1 Retention | D7 Retention | D14 Retention | Cumulative ROAS After D14 |

| Korea | 82% | 62% | 48% | 181% |
| Japan | 71% | 51% | 42% | 358% |
| Taiwan | 62% | 41% | 33% | 222% |
We confirmed that operational designs stimulating cooperation and competition effectively improved retention and ROAS across all regions.
