Blockfall

BLOCKFALL — a falling-block puzzle under the northern lights. Stack the seven four-block pieces, fill whole rows to clear them, and keep the well from filling up. Three modes: Marathon (endless, faster every 10 lines), Sprint 40 (clear 40 lines against the clock) and Ultra 2:00 (score as much as you can in two minutes). Modern rules: hold, a five-piece preview, ghost piece, wall kicks, T-spins, back-to-back bonuses, combos and perfect clears. Plays with a keyboard or a touch screen (buttons or swipes). Music: "Korobeiniki", the 19th-century Russian folk song, arranged and synthesized in code (WebAudio) — it speeds up as the levels rise. Everything is drawn and played by the game's own code: no images, no audio files. Best scores and settings are saved per device.
