Train Sort Jam Puzzle

Train Sort Jam is a color-sorting puzzle where players route trains onto matching tracks, easy to read, deviously hard to master. Delivered full-cycle with a level pipeline built for post-launch content velocity.

Sorting puzzlers are a crowded genre where retention is decided by the difficulty curve: too flat and players churn from boredom, too spiky and they churn from frustration. The brief demanded a level pipeline that could be tuned from data, not designer intuition.

KEY REQUIREMENTS

• A level format designers could author and tune without engineering time
• Difficulty curve instrumented per level: attempts, time, quits, skips
• 60+ launch levels with post-launch batches sustainable at low cost
• Rewarded ads as the primary monetization without paywalling progress

• Data-driven level format (ScriptableObject-based) with an in-editor validator that catches unsolvable configurations before they ship.
• Per-level funnel analytics, attempts, completion time, quit points, skip usage, feeding a difficulty dashboard.
• Post-launch difficulty re-tuning: levels with outlier quit rates were rebalanced in the first update cycle, smoothing the retention curve.
• Rewarded ad economy centered on skips and hints, monetization that players opt into precisely at the difficulty spikes the data reveals.
• Color-blind safe palette verified across all track/train combinations.
