Main page: Bloons Tower Defense Impersonation/Story Mode

Story Mode, otherwise known as Campaign Mode, is a game mode that features a lengthy story-based and progressive journey venturing into different regions and areas as well as boss levels and stages, unlocking new towers and tracks as well as encountering new bloons along the way.

Selection Mode
Selection Mode functions almost exactly like the gameplay in iterations such as BTD5 and BTD6: select a map, select a difficulty and game mode, and play, simple as that.

There are a total of 17 different game modes in BTDI's Selection Mode, all of which are accessible in different categories of difficulty per map: Easy, Medium, and Hard. To unlock a specific game mode, the previous game mode must be unlocked, starting with the respective Standard Mode of a specific map. The Standard Mode option for all grades of difficulty is unlocked by default for all maps.

Trivial Difficulty:
Trivial Difficulty is BTDI's equivalent of the Easy Difficulty in BTD5 and BTD6. Towers cost around 85% of what they would cost in Medium Difficulty, bloons move slower than in Medium Difficulty, the player has 200 lives, and the game mode's icon itself depicts a baby monkey.
