## Gameplay

*Main article: List of Stages (HBT21)*

Each level has a different hexagon grid of bubbles of 4 to 8 different characters (KOYA, RJ, SHOOKY, MANG, CHIMMY, TATA, COOKY, and VAN) and sometimes obstacles (known as Obstacle Bubbles). The basic move of the game consists of tapping one bubble to align sets of three of the same colours, whereupon they disappear, causing bubbles above them to collapse into the space left behind, often resulting in chain reactions. The level's objectives must be met before the player runs out of moves (or Popoking reach to the crown on boss levels); in each case, the player must earn enough points to get the any coins and a Story Key in the moves system.
