⚙️ Challenge Setup
CLASSIC NARRATIVE MODE
The 27-0 Decision Challenge
Manage a real franchise through 24 regular weeks, injury crises, and 3 playoff battles.
Step 1 · Choose your franchise
CAN YOU GO 27-0?
No NFL team has ever won every game in a single season — and 27 straight is beyond anything the sport has seen. You are head coach, general manager and team builder. Pick a franchise, then make ten season-defining decisions while the wins pile up: rest the QB, work the trade deadline, handle the locker room, survive the schedule and win the Super Bowl.
Original simulation using fictional NFL-style teams and players. Not affiliated with the NFL. Progress saves automatically.
THE CORE LOOP
Pick. Decide. Survive.
Every 27-0 run is a story told in decisions:
- Choose your franchise — twelve teams, three tiers, one weakness each.
- Play the weeks — bursts of games build the record, the box scores and the streak.
- Face the events — QB shoulder injuries, holdouts, the trade deadline, snow games. Three choices, no perfect answer.
- Win the Super Bowl — finish 27-0 and enter history. Or read why you fell short and try again.
WEEK 8 · DECISION POINT
Your starting QB has a shoulder injury.
