Target Blast begins with players facing a bomb on a platform. A countdown begins as soon as the bomb is touched, with the goal being to dole out as much damage as possible before launching the bomb toward a target-populated infrastructure to the right. Points are earned both for destroying the structure and for cracking the clusters of targets inside, but your freshly-crafted rubble can also destroy its neighbors, making point-rocketing combos possible.
A player's final score is calculated after two rounds, though it's unclear whether each round's structure will vary, if your destruction is undone, or if the second turn is just spent dealing with what your first shot missed. Sakurai added that Target Blast scores will contribute to a player's Global Smash Power, which plays into Nintendo's skill-based matchmaking for Smash's online multiplayer.
