Classic

Classic, more commonly called Classic mode, is a Solo game mode in Super Smash Flash and Super Smash Flash 2 in which the player fights in a series of battles, one after the other, while also participating on bonus rounds and culminating with a fight against Master Hand.

In SSF2, raising the difficulty level of Classic mode increases opponents' computer level, as well as their launch resistance and knockback. This can make even the light and weak characters difficult to fight.

In Super Smash Flash 2
Classic mode was confirmed during the second McLeodGaming Direct. It is similar to previous iterations of Classic mode and includes ten levels in all:

Trivia

 * It was originally planned for Classic in SSF2 to have a new feature called the "Peril Roulette". As seen in the second McLeodGaming Direct, this feature would have given advantages to the opponent or handicaps to the player, depending on the difficulty setting.
 * According to developer, James TSON Hadden, this feature has been dropped from the game and will not be included in a future update.
