Play currently integrates with a microservice maintained by Olivier and Richard that extracted logic from our legacy systems. It works great, but we want to build a more integrated experience into Play. This was initially avoided due to time constraints and wanting to avoid future footguns due to lack of analysis, so the current integration is designed to be easily abandoned and replaced.
To facilitate a sane migration, consider that brackets have the following components:
Seeding teams into and between series
Can be random to initialize or based on standings of a prior schedule or series
Advancing teams between games within a series
Winner/loser of a prior game
Notes
Can use the ScheduleTeam order to determine the initial seeding
Should integrate this into the new generate games flow
Add a new “Brackets” option after total games per team and single/double rotation
Additional step added for selecting the bracket options
DraftGames will need to be able to link with some version/equivalent of GameBracket. All dependent games must be published at once
Examples
PCAHA U13A Playoffs
PCAHA uses a combination of different brackets during playoffs, segmented by team tier.
All teams start in the 1st round as single elimination, top 8 teams advance to a 4-point series based on 1st round standings (6v8, 1v3, 5v7, 2v4), and top 4 teams advance to final 4, based on final four standings (1v4, 2v3), which determines the winner by a round robin format.
Final winner advances to BC Hockey’s Championships. All eliminated teams play in a presidents series using round robin.
Tier 1-4: 1st Round → 4-Point Series → Final 4
Presidents Series 1-10
Requirements
Each series has it’s own standings within the same schedule (e.g., groups)
Need to be able to seed games based on standings in another group
Either manually or automatically based on maximum ranking
Must be able to have dependencies between games to advance teams within a series
Models
BracketTemplate
Available system templates that can be used
Currently handled by brackets service
Property | Type | Description |
|---|---|---|
id | uuid | |
name | string | |
description | string | |
totalTeams | number | Total number of teams |
type | enum | Single Elimination, Double Elimination, False Double Elimination, Triple Elimination |
template | jsonb | Graph of dependent games that would produce GameBrackets and can be parsed for a bracket UI Format TBD |
GameDependency
Renamed from GameBracket. This model describes the dependencies for a game.
TODO: How to handle DraftGame? targetType/homeTargetType? DraftGameDependency?
Without this, brackets must be immediately published. All dependent draft games would need to be published at once.
Property | Type | Description |
|---|---|---|
id | uuid | |
gameId | id | Game that will be affected by dependent games |
| id | Bracket template |
referenceId | id | Template reference |
homeGameId | id | Dependent game for this game’s home team |
homeResult | enum | Expected home team result of the dependent game Winner, Loser |
homeSeed | number | This references the ScheduleTeam order. Reseeding games will update the home team to be based on the ScheduleTeam with the same order Cannot be used in combination with homeGameId/homeResult |
homeLabel | string | Label to describe what the home team will be. Will default to “Winner of game xyz” based on homeGameId/homeResult or “Team 1” based on homeSeed, so not necessary in most cases, except maybe to describe seeding from other schedules/groups |
awayGameId | id | |
awayResult | enum | |
awayLabel | string | |
awaySeed | number |
Implementation
V1
Select Teams can be used to seed a series
Need to fix the sort by schedule rank; this doesn’t seem to work
Confirm if groups are showing up and can be filtered and added into
Add a way to reseed teams into games after they’ve been generated
This would need to be a manual operation that’s available in the schedule menu to trigger the change.
Brackets service to start populating homeSeed/awaySeed so that Play is able to reseed games
Bracket service needs to account for team order and groupId
V2
Add BracketTemplate to replace the bracket service
Integrate GameDependency into admin and website to show dependent games clearly
Automatic rules to seed teams between series
