Classic

This mode will let you battle through six stages, each with varying twists. These stage conditions are set randomly; some will require you to fight a giant enemy, Pit you in a 1-vs-2 battle, or in a 6-man Multi-man match. You can increase the Intensity (difficulty) by wagering gold. This will award you with better prizes upon completion. Increasing the Intensity makes enemies harder to launch, makes them more aggressive and challengingly effective, and give you some rare chances where you have to fight another CPU-controlled team. In this mode, you can continue after a game over at the cost of your score and some of your collected loot so far.

When proceeding to the next stage, you'll find three routes leading to different enemy groups. The red path usually has more coins but with more difficult enemies while green represents standard and blue leads to the easiest path.

Before a match begins, you'll see a roulette in the lower screen. You can press any button to stop it and whatever the reward it displays once it stops, that's what you'll earn after completing the match.

The last boss changes depending on the intensity you've set. The attack patterns and effectiveness of these bosses will vary greatly with the intensity currently set. They can even take different forms in higher difficulties. Some specific characters can also be unlocked by clearing Classic mode in different Intensity settings. Refer to this link for more details.

After successfully defeating the last boss, you'll see your total score on the top screen while the trophies, gold, and other loot you collected in the lower screen. You'll also unlock your character's trophy.

Next, you'll be taken to the credits screen. This isn't an ordinary credits screen either; you can control your fighter and hit the names of the staff moving upward. Doing this will slowly fill up the blank tiles in the background, revealing a portrait of the character you're using. Take note of the locked portions of the portrait in the background; hitting a name near that background will fill it up so make sure to move around and keep filling up those blank spaces.
