The Idolmaster Shiny Festa (Japanese: アイドルマスター シャイニーフェスタ, Hepburn: Aidorumasutā Shainī Fesuta, officially stylized as THE iDOLM@STER SHINY FESTA) is a series of three Japanese rhythm video games developed by Namco Bandai Studios and published by Namco Bandai Games.

The games are part of The Idolmaster franchise, and were originally released on October 25, 2012 as Honey Sound (ハニー サウンド, Hanī Saundo), Funky Note (ファンキー ノート, Fankī Nōto), and Groovy Tune (グルーヴィー チューン, Gurūvī Chūn) for the PlayStation Portable in Japan.

They were the first games in the series to be localized into English, and were released for iOS on April 22, 2013 as Harmonic Score, Rhythmic Record, and Melodic Disc, while retaining their original names for the Japanese versions.

Each game features a different array of characters and songs, and also includes an original video animation episode produced by A-1 Pictures and directed by Atsushi Nishigori.

The games were described by reviewers as accessible to the franchise's new and existing fans, but the iOS releases were criticized by journalists for their prohibitive pricing.

[1][2] In Harmonic Score and Honey Sound, the selected members are Haruka Amami, Chihaya Kisaragi, and Azusa Miura, and they are joined by Ritsuko Akizuki, who also performs in the festival, as their producer; in Rhythmic Record and Funky Note, Yayoi Takatsuki, Iori Minase, Hibiki Ganaha, and Ami and Mami Futami are chosen to attend the festival with the protagonist Producer; lastly Miki Hoshii, Yukiho Hagiwara, Makoto Kikuchi, and Takane Shijō make up the group of idols chosen to attend in Melodic Disc and Groovy Tune.

[1][3] Like other games in the genre, the player plays the main portion of Shiny Festa's gameplay, Stage mode, as he or she listens to a selected song.

[1][5] The player is scored by these presses' accuracy in timing and direction, for which he or she is given one of four ratings: Perfect, Good, Normal, and Bad.

[4] At the end of each song, a result screen is displayed to player, and his or her performance is rated with a letter grade, a numerical score, and a percentage that represents his or her accuracy.

[2] These items can then be used to customize the game's appearance or adjust gameplay elements,[2] such as straightening the Melody Lines' shapes or causing the player to gain fans quicker.

[8] He also wanted to create an Idolmaster video game that, while maintaining a producer's viewpoint, has a lighter feel and would allow the player to hum along to the idols as he or she plays.

He pointed out that the rhythm game genre fell in line with these two desires, and this led to the development of Shiny Festa.

At the same time, the team also wanted to create scenes where the series' thirteen idols would be able to appear together, and chose to use pre-rendered videos to make this possible.

[10] The PSP games' first printing also included a "backstage pass" that granted access to an online merchandise store, a product code for the song "The World is All One!"

to be used in the games, and a serial number that granted a special Shiny Festa version of Haruka Amami for use in The Idolmaster Cinderella Girls.

[25] Gay and Chuang both agreed that the simple gameplay becomes appropriately difficult with the higher difficulties,[27] while ASCII Media Works' Lipton Kumada noted that the game becomes harder as variations such as simultaneous and long icons are added.

[31] Technology Tell's Jenni Lada noted that the PSP version would be cheaper when imported, and criticized Bandai Namco Games for "setting [the release] up to fail".

[27] Likewise, Kumada felt the iOS games were too expensive as mobile apps, but thought it was a "bit of a bargain" in comparison to the PSP versions' full retail prices.
