Grand Games
Grand Games (Grand Games Oyun ve Yazılım) is an Istanbul-based hybrid-casual mobile game studio founded in early 2024 by Bekir Batuhan Çelebi, Mehmet Çalım, and Mustafa Fırtına, a team that previously built Zen Match at Moon Active. The studio develops genre-defining puzzle games for iOS and Android played by millions worldwide, including Magic Sort, Car Match, and Block Out, and has grown to six live titles with fivefold year-over-year revenue. It has raised roughly $103M across three rounds, most recently a $70M Series B led by Balderton Capital's Growth Fund in May 2026. Grand Games publishes consumer mobile games and does not currently expose a public developer API, SDK, or developer portal.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Grand Games is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Grand Games scores 11.0/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

The organization behind the API
Grand Games is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
