Super Smash Bros. Brawl/Modes

Tourney
Tourney mode might give you a hint of what it is. A tournament! In Tourney mode, you have a tournament which can have up to 32 players. You decide(in the settings) how many players you want per round - 2, 3 or 4. The tournament carries on until someone reaches the finals and wins! The Tournament mode is for deciding who is the top player. If you don't have other players to play with, you can play on your own while all the other competitors are computer players.

Special Brawl
In comparison to a regular Brawl, Special Brawl allows you to have a little more variety with your matches. Toggling the options, you could simply have an Invisible Brawl where characters are invisible, a more complex Mega Heavy Brawl that uses big characters with high gravity, or if you like, a Stamina Flower Curry Fast Brawl that involves HP, a permanent flower, permanent curry, and fast speed!

Adventure
Adventure mode is a side scrolling game. Playing through will allow you to unlock almost every character. You can also collect many stickers, trophies, and finish a few challanges!

Stage Builder
Stage builder is one of the really entertaining sections of the game and... you get to build your own stage! Customised stages! You create the stage by selecting the size, background, floors, other stuff like ladders and spikes and finally music. Sadly, you can only choose music from the game, not any music that you like. Thankfully, you can save the stages you have made on an SD card and play that stage as many times as you want. If you have Wi-Fi connection, you can submit your stages to Nintendo and even receive stages that other players have made around the world!

Classic
This mode consists of 12 rounds. The Target Smash bonus stages appear after rounds 4 and 10. You'll be fighting characters from different franchises. You'll sometimes fight with an ally, fighting against a duo, a giant, a team of opponents, a metal opponent, and round 11 there are 3 random opponents from random franchises. Round 12 is the final stage, You'll be fighting Master Hand towards the end.
