Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.，更多细节参见safew官方下载
For a game to legally be counted as "gambling" in most jurisdictions, it has to pass a three-part test: a player has to pay money (1) for an outcome that's materially determined by chance (2) in the hopes of receiving something of value (3).
