How Skirr is made

The tools behind the game, and what's left out

Built with Apple's own frameworks

Swift and SwiftUI for the app and its menus
SpriteKit for the board, the tiles and the effects
GameplayKit for the board generator and the Daily board's seed
GameKit for Game Center leaderboards and achievements
StoreKit for Skirr Pro

What isn't in it

Just as importantly, there are no third-party SDKs and no advertising SDKs in Skirr. Nothing in the game reports on you. See the privacy statement.

The look

Tiles, keys and titles are set in Fredoka, and everything else in Nunito, both under the SIL Open Font License. This website uses the same fonts and colours as the app, and the board on the home page follows the game's rules.
