There are two 'Wall' rules in place on TripleTriad.com, both are useful
when playing against or with higher level cards, mid levels
are not as effective. TripleTriadX.com has opted for traditional rules, and so only offers Same Wall.

On the diagram above, the edges marked in blue all have an Ace (10) value (although this blue marking does not appear in the actual game). Therefore, the blue Behemoth card will be turned over by the red Bahamut card because there are two pairs of values...the two sides with 6 paired, and the Bahamut A side paired with the wall.

In this diagram, the Anacondaur card (red) turns over the Diablos card (blue) because the values add up to the same number...A + 5 on the Anacondaur's left side, and A (the wall)+ 5 on the top side.
