Standard and Special Rules
Standard rules provide quick easy game-play. Use special rules to add new layers to the game-play with "Audible", "No Huddle", "Final 2:00", and "Injury". Solitaire provides for one-player game-play and can be used only with standard rules.
Standard Rulebook

Sixteen page rulebook covering the rules for basic game-play. The quick-start-guide at the front should be all you need to start playing with the subsequent pages providing a detailed reference. Includes visual aids of play card functionality and the use of the clear down-and-distance markers.
The RedBlue and OrangeGrey rulebooks are not materially different.
Special Offense Rules
Audible

Want to change the offense play at the line-of-scrimmage?
Use the Audible special offense skill to let you place two offense play-cards with the same personnel face-down. The defense then places their play-card face-down. The offense then picks which play-card to use and removes the other one (returning it to their stack of play-cards). Fliip the cards over to see the outcome. It’s that easy!
The offense can use its 12 play-cards and the defense can use its 12 play-cards for the entire possession.
No Huddle

Special Defense Rules
Injury

Want to simulate the impact of an injury in your game-play?
Use the Injury special defense skill to choose and eliminate one of your opponent's three offense personnel groups for one possession. At the start of the possession, the offense must set-aside the four offense play-cards from the eliminated personnel group (as selected by the defense).
The offense has the remaining two personnel groups (eight play-cards) to choose from during this possession. These eight play-cards are available for the entire possession (no discarding).
The offense can use its 8 play-cards and the defense can use its 12 play-cards for the entire possession.
Final 2:00

Want to add the pressure of a ticking game clock to the end of the game?
Use the Final 2:00 special defense skill to limit your opponent's last possession on offense to eight plays. At the start of the possession, the offense must select eight offense play cards to use during the possession and set-aside the other four play-cards.
After each play the offense discards the offense play-card used on that play. If the offense still has possession after the eighth play-card is discarded then they may choose to punt, attempt a field-goal, or simply turn over possession to the defense.
The offense starts the possession with 8 play-cards and ends the possession with none. The defense can use its 12 play-cards for the entire possession.

Solitaire
Solitaire

Solitaire provides for single-player game-play.
Offense and defense play-selection spreadsheets function as proxies for the opposing player.

Situational information is limited to fourth down to permit fast and easy game-play.
