Touhou Spell Bubble

In Touhou Spell Bubble, the player is given colored bubbles, which they fire from the bottom of the screen onto a pile towards the top. The rate at which the player can fire bubbles corresponds to the tempo of the music. When three bubbles of the same color are connected, they pop, giving the player points. If a large enough group is destroyed, a rhythm microgame will initiate, requiring the player to rhythmically press the button to the song's timeline (seen on both far left and right) to receive further points and send colorless junk bubbles to the opponent.

Touhou Spell Bubble features a story mode told from either Reimu and Marisa's perspectives, both containing 22 levels each. Using visual novel-styled cutscenes and gameplay, it tells the tale of Marisa's newly developed, magically charged game "Spell Bubble" and the ongoing mysteries regarding the upcoming tournament surrounding it.

On 23 January 2020, Taito released a gameplay trailer for Touhou Spell Bubble on their YouTube channel, and announced the game's release date. The game was released in Japan through the Nintendo eShop on February 6, 2020, and internationally on October 29. Physical copies were released in Asia in autumn 2020. The company has referred to the game as "Puzzle Bobble meets Touhou Project."

The music of Touhou Spell Bubble was used in promotional material, with Taito releasing the names of composers in January 2020. The game features doujin songs including "Bad Apple!!", "Marisa Stole the Precious Thing", "Night of Knights", and "Cirno's Perfect Math Class".

Touhou Spell Bubble received "generally favorable reviews", according to review aggregator Metacritic. Nintendo Life's Pete Davison commended the gameplay, music, and artwork, but criticised the lack of an online multiplayer. Digitally Downloaded's Harvard L. was more critical, stating that "the elegant simplicity of Puzzle Bobble was being tainted", resulting in "a game about instincts rather than planning".

He considered both the story and gameplay too difficult to understand, and argued that it was inferior to the original Puzzle Bobble. Siliconera's Jenni Lada gave positive remarks to the "unbelievably satisfying" gameplay, and "amazing" music. Lada later went on to call it one of the best games of 2020.
