Plus Wall is a spin-off of the Plus rule.
The Wall (the edges of the entire board) is given the value of 10. Placing a card next to an opponent's card and with the adjacent values of the two cards being equal to the adjacent value of the card you placed and the Wall is Plus Wall.
Below is an example:
Tip: Plus Wall is a very good way to equalize a game when playing against someone with higher levels. The trick is to choose cards with a high side to join to the opponent's card and a low side to connect to the wall. The difference between the two depends on the levels in play.
Plus Wall is also able to lead into Combo, see game rule section for the Combo rules.
