All Star Mode is another mode in Super Smash Bros. for 3DS and Wii U. Like the previous games, you have to defeat every character (including DLC characters if owned) in several rounds. The mode is available at the start with only the characters unlocked. It is available on easy, medium, or hard. If all characters are unlocked (DLC excluded), then the mode is known as the True All Star Mode.
Matches
There are a total of seven matches in All Star Mode. All of the fighters are ordered and grouped based on his or her first appearance. On the 3DS, the fighters are in chronological order. In the Wii U, it is in reverse chronological order. Also, the stages are based on the time period.
The damage you have carries on to the additional rounds. To minimize damage, use powerful, quick, and long range attacks to launch characters as fast as possible. Your attacks are also more powerful. Beware of counters, reflectors, and extremely powerful moves like the KO uppercut. Do not forget that you can not continue after being KO'ed.
Rest Area
After each round, you end up in a Rest Area. It shows the next set of fighters as well as the time period. The fighters defeated also appear in the background.
Health items also appear. If all characters are not unlocked, there are two Maxim Tomatoes, a Fairy Bottle, and a Heart Container. Otherwise, there are one Maxim Tomato, a Fairy Bottle, and two Heart Containers. Try to conserve health items for later rounds. Also, moves that cause or heal damage like Flare Blitz and Deep Breathing do not cause or heal damage.
Rewards
At the end of each round, you get coins. In the rest area, there are trophies and custom parts available. Getting KO'ed does not make you lose any of these rewards; you leave with just those rewards.
