# Hundred Doors

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

- Steam appid: 3892240
- Developer: Ink Ribbon Studios
- Released: 2026 · Genre: Casual · List price: $4.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $194 to $291 per month (mid $243)
- Opportunity score: $243/month at x1.00 dormancy multiplier

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $440 |
| After VAT / sales tax (-13% blended) | $383 |
| After refunds (-9.5% median) | $347 |
| Net to developer (after Steam 30%) | $243 |

## Monthly review counts, oldest to newest (5 months)

## Missed seasonal-sale revenue (modeled)

Skipped 1 Steam seasonal sale window(s) in the last 5 months. Running a -50% discount in those windows is modeled at +$42 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## 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.
