Resort Anthem is the 18th entry in to Konami's beatmania IIDX series. Which in turn is a follow up to their beatmania series.
The gameplay is still the same as in beatmania, with the addition of two extra keys. There are eight columns on the screen, corresponding to each of the keys and the turntable. While playing, small horizontal bars fall down these columns, and the player must press the right key corresponding to the lane as it reaches the red line. Keys 1, 3, 5, and 7 are white, 2, 4, and 6 are blue, and the scratch lane is red. Every time a key is pressed or the scratch is played, an instrument is played to complement the song. In order to hear the song correctly, the player must get the bars on the right timing. Depending on how accurate you hit the note, you will receive a rating of your performance in real time above that note, going from GREAT (a flashing one, officially known as JUST GREAT, meaning perfect timing, a regular GREAT meaning very close), GOOD, BAD, and POOR (the latter for not hitting a note at all). Depending on how good you perform you will raise or lower your approval rating (known as the Groove Gauge). A Groove Gauge at 80% is needed to clear the song.
