Leaves of Blocks

Free SwiftUI iOS puzzle game with no ads, no tracking, and no in-app purchases

Leaves of Blocks is a completely free 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.

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, and efficiency grades from A+ through D.

Tech: SwiftUI, Core Data, iOS 18, Xcode, Fastlane

Features

Smart tiered difficulty system that responds to player skill
Performance analytics with A+ through D efficiency ratings
Solvability guarantee using recursive backtracking algorithms
Smooth drag-and-drop with haptic feedback at 60fps
TestFlight and App Store deployment via Fastlane
