A booster draft is traditionally played in 8-player groups called “pods.” Each player receives three booster packs, usually from the same set. You open the first pack, pick a card, and then pass the pack to the next player.
How to draft: First, players sit around a table in a semi-circle. Each player then opens a booster pack and picks a single card without showing the other players. Each player then passes the remaining cards to the left, and continues drafting from the new cards they get from the player on their right.
To have a Booster Draft, you need three things: 3 Booster packs per player from the current draft format. 8 total players (It's possible to draft with fewer than 8, but 8 is the number needed for sanctioned Magic drafts) A healthy supply of basic lands.
After the draft, players take their pool of 45 cards and build a deck with a minimum of 40 cards using any number of the cards they drafted and basic lands. A standard Cube Booster Draft emulates drafting with sealed booster packs. Drafts are usually 3 packs of 15 cards, and often played with 8 players.
You, along with everyone else at the table, open one pack each and select—"draft"—one card from that pack. Then you pass the rest of the cards to the player on your left. The packs get passed around the table until all the cards are gone. You repeat this process for the second pack, passing to the right.
Each player must bring three boosters (or 45 cards per player). To begin a Winston Draft, players open their boosters without looking at the contents and combine all of the cards together (forming a card pool of 90 cards in a two-player draft).
You could try a Winston Draft. Here's how it works. Each player brings three booster packs. Open ALL of the boosters and shuffle them together without looking at them.

At the start of Commander Draft, each player opens one of three booster packs and drafts two cards into their card pool at a time. This play style is generally meant for increments of four players, and the seating arrangement should be at random.
