The Line Bomb is an item that can create a line of bombs when the right button is pushed. It makes it easier to insert the maximum number of bombs at one time. Line Bomb can only be used when the player has more than one bomb in their possession.
A good strategy for using Line Bomb is to place all bombs next to a bomb that's about to explode. In this case, opponents may be caught in the explosion. Line Bomb can be used for surprising players.
Another strategy is to deploy a bomb and wait for it to nearly explode. Before it explodes, use the Line Bomb to the direction of the opponents. It's best to use it when you are fast enough to escape, in other words, have some speed items.
