Stock match is a match type found in Versus in Super Smash Flash, Melee, and in the Group section of Super Smash Flash 2. This mode allows the player to play matches based on the amount of lives. If the player runs out of lives, they are eliminated of the match, while the only possible action is pausing. If it is a one versus one match, the opponent wins. Otherwise, the remaining players continue to fight. The player may determine how many lives every character in the brawl has, from one to ninety-nine. During the battle, the amount of stock shows up next to the character's art and damage counter, and in this mode, the match ends when the following conditions are met:
- Free for All: All opponents have no lives left while one is still standing.
- Team battle: All opponent teams' members have no lives left.
This mode can be combined with Time match for a match with a time limit and has rankings based on the amount of lives left at the end of a match. However, there is a chance that it may result in a Sudden Death.
