Turn

Turns in Bloons Card Storm determine when players can play cards and use Hero Abilities. The player that can perform actions switches on each turn. In modes with an AI opponent, the human player always goes first, while in competitive modes, the turn order is assigned at random.

Every turn has three major phases: the start-of-turn phase, the middle phase where the player can act, and the end-of-turn phase. In the start-of-turn and end-of-turn phases, the player cannot perform any actions and any effects that trigger in these phases occur in a specific order. The middle phase begins immediately after the start-of-turn phase ends, the end-of-turn phase begins once the player ends their turn or their timer runs out, and the next player's start-of-turn phase begins immediately after the previous player's end-of-turn phase ends.

The term "turn" is used in-game to refer to both the individual turns of each player, as well as the turn counter (represented by a number inside a blue square in the top-left corner of the UI), which starts at zero and increments at the very start of the first player's turn. It is possible for actions to occur on turn 0; in Daily Challenges where players start with a Bloon in play, Zee Jay's Passive Awesomeness activates on turn 0, before players choose their opening hand, and can activate again on turn 1. Similarly, the Storm counter increments at the very end of the second player's turn, though if the counter is at zero, it activates during both player's turns.
