# A Solitaire Mystery

> ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title.

- Steam appid: 3743220
- Developer: Hempuli Oy
- Released: 2025 · Genre: Indie · List price: $9.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $212 to $318 per month (mid $265)
- Opportunity score: $331/month at x1.25 dormancy multiplier
- Est. lifetime owners: 8.8k · Est. lifetime net revenue: $29.4k
- Review sentiment: 92% positive across 284 reviews (274 from Steam purchases)
- Review velocity: 3.2 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 4 months ago
- Studio active elsewhere (2 titles tracked), so this one may welcome a partner
- Last build shipped 4 months ago
- Store page localized in only 1 language(s)
- Last discounted 8 months ago, 1 sales in the last 12 months

## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $481 |
| After VAT / sales tax (-13% blended) | $419 |
| After refunds (-9.5% median) | $379 |
| Net to developer (after Steam 30%) | $265 |

## Monthly review counts, oldest to newest (13 months)

166, 27, 7, 7, 16, 24, 13, 5, 5, 2, 2, 1, 4

## Missed seasonal-sale revenue (modeled)

Skipped 6 Steam seasonal sale window(s) in the last 13 months. Running a -50% discount in those windows is modeled at +$8.6k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- french: 1% (game NOT localized in this language)
- koreana: 6% (game NOT localized in this language)
- russian: 3% (game NOT localized in this language)
- spanish: 1% (game NOT localized in this language)
- japanese: 12% (game NOT localized in this language)
- brazilian: 0% (game NOT localized in this language)
- german: 1% (game NOT localized in this language)
- english: 68%
- schinese: 7% (game NOT localized in this language)

Localization gap: 32% of measured reviews are written in languages the game does not support (top: japanese). Localizing is likely immediate market expansion.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
