Events are time-limited activities that can be separated into few categories. This segregation is mostly unofficial as the game/its developers only directly named featured, web, and bingo events.
While in-game Supplies are referred to as events as well, info about those won't be included on this page.
Featured Events[]
The biggest event in a version, usually lasting for about a month. They often feature unique story not related to the main universe.
Debut Events[]
Events that reward Captains for playing a new story chapter/game mode, an expansion to pre-existing feature, etc. or ones that make it easier to access previously released content such as lowered stamina consumption for old story stages.
Time Capsule Events[]
Limited-time shops with stigmata, weapons, and outfits that could be obtained via past events. Captains may use 
Asterite, 
HOMU's Legend Proof, 
Special Outfit Coupon, or 
B-Chip to purchase the items
Login Bonus Events[]
Events that automatically give all Captains meeting the level requirements a bonus item upon their login into the game. Last for a minimum of 3 days - usually 7 days. They may sometimes require that Captains go to event screen to manually claim the item(s).
Web Events[]
Events that open a browser in-game or require Captains to go to a specific website.
These events require a device that supports WebGL.[1]
Bingo Events[]
Events with multiple titled boards that can be flipped to reveal either an X or an O. Getting an X gives nothing in return, but getting an O may reward players with small amount of currency, usually Asterite. A board is cleared by forming a line with O tiles, achieving a BINGO. Each board has its own main reward that is given upon achieving a BINGO. The event's most important reward, usually a stigma, is often on the pre-last board.
Puzzle Events[]
Events with missions that give small rewards and unlock a mosaic/puzzle piece upon completion. Once all the pieces are unlocked the main event reward, usually a stigma, is given to the Captains.
HOMU's Treasury Events[]
Events with a titled board. Captains can consume 
HOMU's Golden Key which are bought via 
Crystals or B-Chips to flip the tiles. Unused HOMU's Golden Key will be saved and can be used in a future treasury event.
Top-up Bonus Events[]
Events that give Captains bonus items such as S-rank Battlesuit Rank-up Stamps upon reaching a specific Top-up amount.
Spending Bonus Events[]
Events that give Captains bonus items after doing specific amount of Supply drops. The bonus item be can be a directly-awarded outfit or similar or an event-limited currency that can be used to purchase various goods, including outfit(s).
Miscellaneous Events[]
Events that couldn't be easily categorized.
