===Modes===
====Battle Mode====
Two players compete against each other on the same cabinet or controller using only three buttons (Green, Yellow, and White) to play the same note chart, and a fourth "action" button (Blue). As a player scores "Great" ratings on notes, a power meter increases near the bottom of the screen, and once it reaches a certain level, the player can press the action button. Doing so starts a [[minigame]] along the bottom of the screen, requiring the players to alternate pressing the action button in time with the song, in addition to playing the note chart. When one of the players misses, an Ojama is inflicted on them.

====Expert Mode====
Introduced in ''Pop'n Music 6'' is Expert Mode (or Expert Courses), similar to Nonstop Mode in other Bemani series. The player selects from a pre-made course of four songs and plays through the selected course with a "Stamina" life bar that does not recover. In this mode, another accuracy score is added, "Cool". This makes songs played in these modes significantly more difficult to achieve high scores on, as the value of "Great" and "Good" are decreased. In this mode, "Great" does not become Fever, and instead "Cool" flashes in a similar manner to how "Fever" is displayed in other modes. Expert Mode was removed after ''Pop'n Music 18 Sengoku Retsuden'', but returned in ''Pop'n Music Lapistoria''.

====Challenge and Cho-Challenge Modes====
Introduced in ''Pop'n Music 5'', Challenge Mode (CHALLENGE モード) is a mode where players are not only scored on their individual songs, but are also given a Challenge Score. Each song is assigned a point value on a scale from 1 to 50 (formerly 1 to 43) regarding to the difficulty, and at the end of a game in one of these modes, the total is tallied. Additionally in these modes, options called "Norma" and "Ojama" may be used to add point values to the player's Challenge Score. A "Norma" is a set goal, while an "Ojama" is an active means of periodically distracting or disrupting the player. Up to two options can be activated at once. On specific numbers, a player may be allowed an "EXtra Stage", an additional stage in which the most difficult charts (EXTRA or "EX" charts) for certain songs may be played and unlocked. EXtra stages use a different gauge than usual, a "Stamina" gauge similar to the [[life bar]] in a fighting game, or ''[[Dance Dance Revolution]]'' {{'}}s Life Gauge, where complete depletion means the end of the song. It was renamed "Normal Mode" in ''Pop'n Music 20 Fantasia''.

Cho-Challenge Mode (超CHALLENGE モード, ''"Super Challenge Mode"'') is similar to Challenge Mode, except that another accuracy score is added, "Cool". This makes songs played in these modes significantly more difficult to achieve high scores on, as the value of "Great" and "Good" are decreased. Starting from ''Pop'n Music Portable'' on console releases and ''Pop'n Music 20 Fantasia'' on arcade releases, "Cool" is always on, regarding to Challenge Mode and Cho-Challenge Mode are combined into one single mode.<ref name="fantasia">[http://vjarmy.com/wiki/index.php/PnM_AC_20#General_Information Pop'n Music 20: Fantasia general information] on RemyWiki.

====Osusume (オススメ, ''Lit. "Recommendation"'')====
Introduced in ''Pop'n Music 9'' is Osusume (オススメ, ''Lit. "Recommendation"'') Mode, where the player is asked a series of questions, and the game provides an Expert course based on the player's answers. It was removed after ''Pop'n Music 11'', but was reintroduced in ''Pop'n Music 20: Fantasia'' as a song category within normal mode, containing a selection of songs the player might like, based on the player's song selection history.

====Net Taisen Mode (NET対戦 モード, ''"Net Battle Mode"'')====
With the introduction of the [[e-AMUSEMENT]] system in Japan, ''Pop'n Music 12 Iroha'' is the first game to feature "Net Taisen Mode" (NET対戦 モード, ''"Net Battle Mode"''). This mode allows players to compete over the e-AMUSEMENT network in real time with players on other e-AMUSEMENT-ready cabinets. In ''Pop'n Music 17 The Movie'', a CPU-emulated version of this mode has been added, similar to the "Taisen" mode found on consumer releases.

====Enjoy Mode====
Starting in ''Pop'n music 12 Iroha'', "Normal Mode", the standard mode of play, has been removed, replaced instead by "Enjoy Mode". Enjoy Mode is a simplified mode for beginners with a reduced song list, simple note charts, and a less complex grading system, in which the player begins with 100 points and is docked one for each note they fail to play properly. Enjoy Mode incorporates many of the games licensed tracks, providing most players in Japan a mode in which they know the songs and can more easily become interested in the game. Enjoy Mode was renamed "Easy Mode" in ''Pop'n Music 20 Fantasia'', and removed as a whole in ''Pop'n Music Sunny Park'', to be replaced with a new difficulty for Normal Mode: "Easy".
