Leaves of Blocks

Open-source, privacy-first SwiftUI iOS puzzle game with no ads, no tracking, and no in-app purchases

Leaves of Blocks is an open-source iOS puzzle game—no ads, no tracking, no in-app purchases. Players drag and drop block shapes onto an 8x8 grid to clear lines. Born out of frustration with ad-laden games like Block Blast, it prioritizes a clean, distraction-free experience and a Whitman-inspired aesthetic.

Built entirely in SwiftUI with zero external dependencies, the game features adaptive difficulty that adjusts piece selection based on player performance, advanced solvability validation algorithms, efficiency grades from A+ through D, and opt-in Game Center leaderboards. The full source is available on GitHub under the MIT license, and a browser-playable build lives on leavesofblocks.com.
