A playmat system includes a series of isosceles right triangle tiles and edge tiles. Advantageously, the triangle shaped tiles and edge tiles have one or of two color or patterns or more. The triangle shaped tiles and edge tiles have complementary edges which allow the triangle tiles to be interlockingly engaged with one another along either hypotenuse edges or like edges to thereby produce a number of different patterns when laid out and interconnected.

A card tile deck includes a plurality of card tiles divided into multiple zones with each of the zones including either a first indicia, a second indicia, a third indicia, or a null indicia. A method of playing a game includes forming a build stack of played card tiles from the plurality of card tiles by repeatedly positioning an active card tile on top of a played card tile with one of the zones of the active card tile substantially overlapping one of the zones of the played card tile. A null indicia can be covered by either the first indicia, the second indicia, or the null indicia. The first indicia or second indicia can be covered by either the third indicia or the null indicia. A third indicia can be covered by the null indicia.
