Crystal Crisis is a competitive tile-matching puzzle video game developed and published by Nicalis, released on Nintendo Switch, PlayStation 4 and Microsoft Windows via Steam in 2019.

Several alternate play styles are available as well, including "Inline", which removes Spark Crystals and functions similarly to a "match-three" puzzle game; "Tag Team", which allows players to switch between two characters in the middle of a battle; and "Memory", which turns all crystals black as soon as they are dropped and challenges players to remember their colors.

Additionally, the game features accessibility options for colorblind players, including the ability to set custom colors for each of the four crystals.

[4] The idea for Crystal Crisis originated from Nicalis president Tyrone Rodriguez, who sought to create a new competitive puzzle game.

Nicalis also reached out to Studio Saizensen, whom the company had worked with on previous titles, and Tezuka Productions for use of their characters, along with the creators of other independent Japanese games, bringing the total roster to nineteen.

[7] In January 2019, it was announced that the game would be delayed a second time until May 28, 2019 in order to add additional features, including new playable character Kawase Umihara and in-game narration by Peter Cullen.
