- Steam appid: 4277310
- Developer: Dandy Games
- Released: 2026 · Genre: Casual · List price: $3.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $486 |

| After refunds (-9.5% median) | $382 |
| Net to developer (after Steam 30%) | $268 |

## Monthly review counts, oldest to newest (4 months)

## Missed seasonal-sale revenue (modeled)

Skipped 2 Steam seasonal sale window(s) in the last 4 months. Running a -50% discount in those windows is modeled at +$167 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.
