Gain 10 yards in four downs to keep your drive alive. Run for steady gains, throw short to move the chains, use screens to counter pressure, or go deep for a bigger reward with more risk. Defense has a counter for every call; mix your plays to stay unpredictable.

Touchdowns earn 6 points. Then kick for 1 (94% chance) or go for 2 (46%). Field goals earn 3; longer kicks are less reliable. Punt on fourth down to trade possession for field position. Each quarter has 22 plays; extra points use none. The other team receives after halftime. A tied final score is a draw.

Yellow flags are rare (3.5% of scrimmage plays). Holding, false starts, illegal shifts, offside, neutral-zone infractions, facemasks, defensive holding, pass interference and roughing the passer can change a drive. Most flags replay the down; defensive holding, facemasks, defensive interference and roughing award a first down. Interference uses the foul spot, capped at the 1-yard line; other penalties use half the distance near a goal. For this arcade league, accepted penalties replace the play result and use one play. Fumbles may be recovered by either team.

Two players share the device: defense chooses first, then passes it to offense. Both teams use the same outcome probabilities. Sound starts when you kick off. Mute it anytime; scoring and gains of 18+ yards bring a short celebration and vibration on supported devices.
