Training is a singleplayer mode in Bloons Card Storm. Prior to version 4.0, it was classified as a campaign under The Basics alongside the Tutorial. It consists of seven stages that can be played in any order. Each stages features a Hero as an AI opponent with a predetermined deck. There are no rewards for playing this campaign and the game does not track which levels have been completed. Like in Duel and Ranked mode, the map is chosen at random and the player can veto the map once per match.
