Turning rewarded installs into meaningful gameplay

For Train Miner, the objective wasn't simply to generate additional installs. The key challenge was acquiring players who would actually engage with the game's idle progression and railway-building loop.

The campaign needed to attract users who would:

• Spend meaningful time playing
• Progress through the mining and train systems
• Return to the game after acquisition
• Engage with deeper gameplay mechanics
• Generate sustainable long-term value

With a progression-heavy idle experience, quality of engagement was more important than raw install volume.

Rewarded acquisition built around player engagement

1Orbit leveraged its gaming-focused publisher network to introduce Train Miner to rewarded audiences with a strong affinity for casual and idle gaming.

Rather than optimizing purely for installs, the campaign was structured around post-install engagement and player value.

Rewarded Playtime Optimization

The campaign encouraged users to move beyond the initial install and spend meaningful time inside the game.

Traffic was evaluated based on rewarded playtime, progression and downstream retention, helping identify publishers capable of delivering genuinely engaged players.

Progression-led Optimization

Train Miner's core gameplay loop — mine → merge → upgrade → build → expand — provided multiple opportunities to identify higher-quality users.

1Orbit optimized traffic toward users demonstrating deeper engagement with these mechanics.

Publisher-Level Optimization

Performance was monitored across the publisher network using downstream signals such as:

• Rewarded playtime
• D30 retention
• LTV
• ROAS
• Cohort quality

Higher-performing sources received greater allocation as the campaign scaled.
