The ultimate NFL stat-counting daily puzzle game.
Gridiron Countdown is a daily football puzzle game where you count down from massive statistical targets (Passing Yards, Sacks, Interceptions, etc.) to exactly 0 using legendary NFL players.
- Select a Goal: Every day, a new statistical category is chosen (e.g., "Count down 50,000 Passing Yards").
- The Penalty Flag: Your first player must satisfy the daily opening rule (e.g., "Must be a Wide Receiver" or "Must have played for the Cowboys").
- Draft Your Roster: Search for any NFL player. Their career stats in the current category will be subtracted from the total.
- Manage Your Timeouts: You get 3 Timeouts. If a player's stats take you over the remaining total, or if you violate the opening rule, you lose a Timeout.
- The Hail Mary: Down to your last Timeout? Use the Hail Mary button for a 2x stat multiplier—but if you bust, it's game over!
- The Two-Minute Warning: Within 20% of the goal, you enter the Red Zone. The field turns red, and the pressure is on!
- ✅ PWA Ready: Install it on your phone or desktop for offline play.
- 🎨 Stadium Aesthetic: Jumbotron-style scoreboard and realistic turf field.
- 🔊 Immersive Audio: Referee whistles, stadium buzzers, and a stadium announcer voice-over.
- 📈 Multi-Stat Categories: Passing, Rushing, Receiving, and Defensive stats (Tackles, Sacks, Interceptions).
- ⚡ Lightweight: Zero dependencies, zero remote fonts, adblock friendly, and 100+ Lighthouse score potential.
