Picture Block Puzzle 2D is a complete Unity game template for building and customizing sliding picture-assembly puzzle games. Developed with the HyperCasual Game Engine, this asset provides the core systems, architecture, and tools needed to create a unique mobile-ready puzzle experience.

Players drag color-coded image pieces across a 2D grid to reconstruct original pictures before the timer runs out. With physics-based sliding, multi-cell shape footprints, and satisfying assembly mechanics, this template offers a polished hyper-casual gameplay loop inspired by popular mobile assembly puzzles.

This game template includes a full puzzle gameplay loop, a time-pressure countdown system, three boosters, and a fully featured Unity level editor with automatic level generation. Every system is modular, data-driven, and designed as a foundation for rapid extension and production-ready development.
