Here are (from what I've gathered) the Inazuma Eleven FootballFrontier rules:

Pre-Game Setup: Choose a GoalKeeper from your deck and play it next to your soon-to-be, face-down deck. Shuffle your deck, place it face-down next to your GoalKeeper, and draw five cards. Place your Turn Marker at zero.

PHASES

Phase 1- Draw (Draw a card from your deck! Refresh -turn upright/vertical- any Exhausted -sideways/horizontal- cards. Move your Turn Marker up one.)

Phase 2- Main Phase (From what I've seen, you can play any character you want onto your bench-regardless of Level- and then move any up onto the field as long as their Level is equal to or less than the Turn Marker.)

Phase 3- Attack Phase (Activate any abilities that activate in this phase if you wish to do so. Some characters have effects that activate when they're "Fired-Up". I'm not sure what this means or how to activate it, but it seems crucial, for most cards have effects that activate when said "Fired-Up" is active on them.)

Phase 4- Shooting Phase (Activate any abilities that activate in this phase if you wish to do so. You can also boost your characters' SP (Shot Points) by playing Super Techniques. These have little requirements too, such as needing certain characters like Axel/Gouenji and Kevin/Someoka, having your Turn Marker at a certain level, and needing other characters of a certain type -be it Wind, Fire, Grass/Earth, Teamwork or Colorless.) Before the end of this phase, see if you can score a goal by attacking the GoalKeeper (provided you got past other players in the Attack Phase) and playing a Super Technique (or usually, using a characters listed Hissatsu in their text box). If your SP is higher than the GoalKeeper's, you score a goal. (This game follows a similar gameplay/game-ending conditions as "GO": Six turns =  two halves to the match, three turns per half. Higher amount of goals wins by the end of the sixth turn!)

Phase 5- End Phase.
