Same Wall is a spin-off of the Same rule.
The Wall (the edge of the entire board) is give the value of A. By placing a card that has an A on it adjacent to the Wall with another number the same value as an opponent's card on the connecting sides the opponent's card will flip. This can also lead into Combo if it is in the game.
Below is an example:
Tip: With Same Wall only cards that are level 9 or 10 can use this rule except for a few lower level rares. Same Wall is also able to lead into Combo, see game rule section for the Combo rules.
