Draft Methods

Winston Draft

In Winston Draft, cards are arranged into piles. On your turn:

1. Look at the first pile
2. Choose to either take that pile or pass to the next pile
3. If you pass on all piles, you must take a card from the top of the pool deck
4. After your selection, add a card from the deck to each pile you passed

Rochester Draft

In Rochester Draft:

1. Cards are laid out face up in "packs"
2. Players take turns selecting one card at a time from the available pack
3. The direction of picking reverses each round
4. When a pack is empty, a new one is opened

Grid Draft

In Grid Draft:

1. Cards are arranged face up in a grid (Default is 3×3)
2. Players take turns to select a row/column of the grid, adding those cards to their drafted deck
3. Replenish rows/columns with new cards from the pool
4. Continue until each player has desired number of cards

Asynchronous Draft

In Asynchronous Draft:

1. Players draft independently at their own pace without needing to coordinate schedules
2. Each player opens their own packs and selects cards
3. Once a card is drafted by a player, it's no longer available to others (unless you enable Allow overlap in player packs)
4. Players can join and make picks whenever they have time
5. Draft continues until all players have completed their selections

Changelog

• [19/05/2025] I have disabled sign in with OAuth for now as there is no advantage to doing this compared to signing in anonymously. I want to avoid storing any user data until it becomes necessary to do that for some functionality (e.g. saving your own cubes). If you previously signed in with your Discord/GitHub account, your data has been deleted from Supabase.
