BeatCombo

BeatCombo is a free browser-based O2Jam-style 7-key rhythm game (VSRG) that runs entirely in your browser with no download and no account required. Notes scroll down seven lanes and you hit them with S, D, F, Space, J, K and L on a keyboard. Drop any MP3 into the chart editor and the game auto-detects BPM and onsets to build Easy, Normal and Hard charts in seconds — no DAW and no manual note placing. Play hundreds of community-uploaded tracks, like and comment on charts, and climb both per-chart and global leaderboards. Whether you grew up with O2Jam Online, osu!mania, Beatmania or DJMAX, BeatCombo brings that same timing challenge to any device with a modern browser. It is free to play, free to upload your own music, and ready for casual sessions or competitive score chasing.
