Executive Summary
Supercell, the Finnish mobile gaming studio behind some of the most recognizable titles on the planet, had a clear brief: mark the Clash of Clans anniversary with something that felt genuinely special, not a printed t-shirt, not a generic corporate gift, but a collection worthy of the IP. Sunday co-developed five fully custom products from scratch, managed the entire process from first sketch to European delivery, and landed 500 units across the continent in three months. The result was a limited-edition internal drop that the team called perfect.
About the Client
Supercell is a Helsinki-based mobile game developer with a portfolio that has shaped modern gaming culture. Clash of Clans, Clash Royale, Brawl Stars, these are titles with hundreds of millions of players and communities that take the brand seriously. That matters when you're making merch. Supercell employees and community members don't just work around these games; they're fans. Anything carrying the IP had to meet a standard that standard promotional merchandise never could.
The Challenge
The brief Supercell brought to Sunday wasn't about logistics. It was about quality.
Most merchandise vendors operate on a simple model: you pick from a catalog, add a logo, place an order. Fast. Predictable. And almost always underwhelming. For a company whose games are known for their art direction and attention to detail, "add a logo to a stock hoodie" was never going to cut it.
The challenge had two parts. First, finding a partner who could actually co-develop fully custom products from scratch, not adapt existing templates, but build from a blank page with Supercell's IP as the creative foundation. Second, owning the entire process end to end. Supercell needed one party to take the brief, run with it, handle sampling and iteration, manage production, and get 500 units to the right people across Europe. No handoffs. No gaps in ownership.
