The Soft Block is a core element of the Bomberman gameplay. It is the destructible turf that appears in almost every Bomberman game.
Example on how to clear Soft Blocks from the stage
Typically, in either Story Mode or Battle Mode, the round begins with the player(s) trapped in a small space by Soft Blocks and Hard Blocks. The player then proceeds to blast away Soft Blocks with bombs in order to reach enemies or opponents. Soft Blocks sometimes contain Items, which will either power up the player or hinder them. In some games, Soft Blocks can contain special Items that are used to power up Charaboms.
Soft Blocks also serve as a way of trapping Enemy Characters or other Bombermen. Strategically, it is usually best not to clear all Soft Blocks from a stage before destroying all Enemy Characters, and not to clear the entire stage at all during Battle Mode, unless you have enough power-ups or talent to deal with the other players effectively, or if Sudden Death has been activated.
