Blockrain
Play classic falling-block Tetris with arrow-key controls and an optional autoplay showcase.
Editor’s Notes
2026-10-16 first-hand review: the Blockrain page rendered its black-grid Tetris boards, score panel, themed example, and autoplay section. The example explicitly says Use only arrows. The page is a demo-style Tetris presentation rather than a single minimal board, so the details should not describe it as a generic click-and-drag puzzle.
