Dance pad / gamepad

USB dance pads and controllers work through your browser's gamepad support. Press a button on the pad once so the browser notices it, then use Controls to map your arrows.

The arcade flow

Insert a coin, pick a difficulty, then choose songs from the wheel. A second player joins by pressing their START on the title or difficulty screen. On the song wheel, tap ↑↑ for an easier chart or ↓↓ for a harder one, press ← and → together to change the sort, and press START twice for options (speed, reverse, boost, hidden…). In arcade mode you get three stages, and an AA on HEAVY at the Final Stage unlocks the Extra Stage. Event mode has no stage limit; toggle it with ←/→ on the title screen. Rank in a difficulty's top five (arcade mode) or set a song record and you get to enter your initials, DDR style; then the ending rolls: the special ending for a final grade of AA or better, the music list otherwise. Leave the title screen alone and the machine dances a DEMO PLAY, then shows the best rankings; any button stops it. On the touch pad, OPT on the results screen shares a picture of your result.

Custom songs

Press Import songs under the screen and pick a .zip or .smzip: one song or a whole pack, with .sm or .ssc charts and their music. They stay in this browser only, and play from Play custom songs on the title screen, with their own high scores. Remove them from the song list below.

Install it and play offline

This page is an installable web app. Press Install app under the screen when your browser offers it (on iPhone and iPad: Share, then Add to Home Screen) and it opens in its own window. After the first visit it starts without a connection. Once installed, it downloads every song in the background (waiting for Wi-Fi on a phone), so the whole game plays offline. In a browser tab, songs you have played keep working offline, and Save all songs offline above the song list, or Save offline on one folder, keeps the rest.
