What are the various modes of fighting in BitLife Ultimate Fighter Pack?
There are two types of fights in BitLife Ultimate Fighter mode pack - League Fighting & Street Fighting. Indicative of its name, the League Fighting is where you fight against other registered fighters to earn a name for yourself in the League. Basically, there will be a ranking, and you take down each of them to reach the number 1 spot and win the League. As you move up the ladder, you will earn a good amount of money for each fight along with XP + Street Creds.

Street Fighting, on the other hand, is the best place where you can practice all your new moves while earning quite a lot of Street Creds. It's more of a practice area, as you won't lose any ranking or money for a defeat.
How to fight in BitLife- Ultimate Fighter Pack

Fighting in BitLife is all about using the correct moves and handling your stamina bar correctly. Before starting a fight, open the Move Set option from the top of the page. Equip the best moves in your inventory that have a very high power damage rating while having low stamina usage points. Ensure to equip at least one move from each of the core categories to avoid getting countered by high-level fighters.

Once the fighting mini-game starts, your main job is to test each of the available moves in your inventory against the fighter and find which one consistently guarantees you a critical hit. Use these abilities continuously throughout the fight to get easy damage and win the fight quickly. Remember, while you can repeat moves that guarantee a critical hit, you should mix them with other moves to avoid being dodged in crucial phases of the fight, as some damage is better than no damage.
How to unlock Fighting Moves in BitLife

You can always unlock new fighting moves to add to your inventory in BitLife. The first way to unlock is by visiting the Skill Move store, where you can spend Street Creds to purchase one of your liking. The other common way to unlock new moves is while training with your coach. Press the Train button at the bottom to hone your skills while continuously learning new ones. Other than these, you can unlock specific moves by finishing certain tasks.
How to recover Stamina & Improve Fighting Stats in BitLife
As mentioned earlier, Stamina is key to winning fights in BitLife. You can recover your lost Stamina after each fight by undergoing Recovery treatment. Press the Recovery option and pick any Recovery method that consumes 10 or More Street Creds. The main reason is that the free methods only increase your Stamina by a small margin, and Street Creds can always be earned by participating in street fights.

To improve your fighting stats, you have to train. Press the Train button inside the menu and select the stat to train that particular one. Remember, in addition to your training, your stat improvement depends on your coach. So, try to hire a good one if your current Coach has a very bad rating. Simply press your existing Coach name, then use the Replace button to search for a new one.
