## Description

The site brings together playful activities and exploratory tools across mathematics, puzzles, geography, music, and visual learning. Visitors can experiment with formulas, solve mazes, play Go, arrange pieces in tangram puzzles, or explore the Rubik’s Cube. Other features introduce mathematical ideas such as prime numbers and map projections, including the Equal Earth projection. The collection also includes a film about scale, an interactive feature related to the shakuhachi flute, and a network activity that users can teach to recognize their own symbol. Rather than focusing on a single subject, hraj.si offers a varied set of compact browser-based experiences that invite users to try things out and discover concepts through interaction. Its straightforward format makes the activities easy to access, whether someone wants to play a familiar puzzle, explore a mathematical visualization, or engage with a more unusual creative tool.
