Gridiron Duels

Two stacks under one roof. Public-facing pages — homepage, leaderboard, marketing — are server-rendered Blade for fast first paint and clean SEO. The interactive surfaces — draft room, shop, achievements — are React / Inertia, sharing auth state through middleware so users glide between server-rendered and SPA pages without ever feeling the seam.

DraftEngine is a single service class that owns the full game lifecycle: create, join, ready-up, pick, score, complete. Every state transition broadcasts an event — PlayerDrafted, TurnUpdated, GameCompleted — through Laravel Reverb. Web clients listen via Laravel Echo, mobile clients via pusher-js. Same channels, identical events, one source of truth.

A player can start a draft on their laptop and a friend can join from their phone mid-pick. Same lobby, same turn order, same animations. That parity is enforced everywhere downstream — there is no mobile version of the draft, only the draft as accessed from a phone.

Games are assembled from two pieces. GameFormat defines structure — 1v1, 2v2 teams, League up to sixteen — and decides player count, draft order, and scoring rules. Modifiers stack on top: CPU fill, Crazy Mode randomized scoring, Time Machine using past NFL seasons. Add a new modifier and the core draft logic doesn't move.

Five services, five domains, one shared coin. Every service owns its slice and nothing else, which keeps the failure modes small and the tests narrow.
