Adjustris brings a flexible falling-block puzzle to your Chrome toolbar. The default Original tab runs Dave VanEe's complete Game Boy homebrew. Move and rotate falling pieces to complete horizontal lines, advance a level every 10 cleared rows, and adapt as the pace increases. Four ready-made piece sets are available immediately, while the built-in editor lets you create custom shapes, choose rotation behavior, change tiles, and arrange your own sets.
