The game is easy to get started, with space puzzle tasks based on mortises and tenon being the core gameplay.

The mortises and tenons that you have cleared on the main levels are collected in the "Collections" section. Players can freely disassemble each structure here. AR-like visual effects show a 360-degree combination of mortises and tenons and also teach national history and culture.

※ Paradise of Imagination
