how to win a solo game in Fortnite?

Have some healing in your inventory. Healing items are blue vials and bottles. If you get damaged, use these to heal yourself. It takes about 3 seconds to heal yourself. Make sure you are in a safe location before healing yourself. Get materials early in the match. Use the pickaxe to attack trees, rocks, as well as wooden, stone, and metal structures to get materials. Avoiding gathering materials in out in the open. Get all the materials you need early in the match while players are still scattered over a large space. Eliminate other players as quickly as possible. If a player engages you in a fight and won't leave you alone, eliminate them quickly. If a player is aggressive towards you and tries to get into your fort, keep building walls so he won’t be able to come in. You can also set a trap for him. A trap is a safest and quickest way to deal with damage to a player inside your fort. Hide from other players. When there are still a lot of players left in the game, you don’t want to create attention to yourself. Creating attention will put you at risk of dying by other players. If you must travel, key your view list. Sneak up on players and deal damage to them. The most effective way to damage a player is to attack them from their blind side. That is where they least expect being attacked. A lot of damage can be done to a player when they don't expect it. Do not give a player time to heal after dealing damage to them. To stop the enemy from healing after dealing damage to them, just spam them with shots. Even if they constantly keep building to keep from getting shot at, it’s okay because if they are busy building that means they are not taking time to heal up. Position yourself so you don’t have to move much. This forces the enemy is forced to push you. This is especially important when you're down to only one enemy. If you position yourself right and force the enemy to push you, that means you will be able to pressure and deal damage to the enemy without having to worry about getting shot at and damaged, while they are running from the storm. This means that they are pressured by you and the storm. I think i helped you if you have questions write me
