Play in the browser
Play TJA charts in the browser: load your own charts in one click or open any .tja. Files are processed only in your browser.
The play page lets you play TJA charts right in the browser, no simulator needed.
Loading a chart
- My charts: once signed in, pick a song from the list and the chart and audio load together.
- Your own files: choose a .tja and an audio file (ogg / mp3 / wav / m4a / flac, optional), or paste the TJA text. Shift-JIS encoding is detected automatically.
Files you open yourself are processed only in your browser. Nothing is uploaded and no credits are used.
Controls
| Key | Action |
|---|---|
| D, K | Ka (rim) |
| F, J | Don (center) |
- Difficulty: switch between the courses in the .tja.
- Speed: 0.5×–1.5× for practice.
- Music / hit sounds: separate volume controls.
- Auto-play: lets the player hit for you, handy for checking that the chart lines up with the music.
On phones you can watch the chart and auto play; to play yourself you need a physical keyboard.
Marking GOGO sections
When playing a chart you generated, you can drag to mark GOGO sections and save them back to the chart.
Comparing engines
Jobs made with multi-engine mode let you switch between each engine's version on the play page.
