Make sure to know the song’s BPM (tempo). Scroll speed will depend on it; for example, a BPM200 song at 1x scroll speed and a BPM100 song at 2x scroll speed will have arrows moving at the same speed. Some songs change scroll speed in the middle. They are typically marked with two BPMs if the song actually changes tempo, but if the chart has gimmicks where it speeds up, slows down, or stutters, it may not be shown in the BPM display in the song selection.
If a difficulty says “Double” and has a green background, it means one player plays on all 10 panels. Unless you know what you’re doing, make sure to avoid these.
Don’t be shy to move around and twist your body. Instead of stepping and returning, walk around on the platform. It will make patterns like ↖↗↖↗ and ↙↘👣↗↖ easier. Don’t be afraid to turn your body to either side! Patterns like ↙↘↗↘↙, ↙👣↘👣↙, and ↙↖👣↗↘ will require you to do so.
