You and your friends take turns strategically placing randomly drawn tiles into a shared arrangement, in a race to finish the pattern goals and be the first to accumulate 16 points. Pay attention to your opponent's goals - your strategy should include building your own patterns and slowing them down! There are 54 pattern goal cards with varied degrees of difficulty worth 1, 3, 7 or 15 points. The 66 unique tiles consist of colorful triangles that form the building blocks of the patterns. On the back of each tile is a symbol that indicates which of the three "Special Action" may be taken on that turn. Purple: you can draw another tile. Green: you can rotate a tile already in play. Orange: you can place the tile corner-to-corner, or move a tile stuck in the middle. Each game is different, depending on the tactics you and your friends employ to assemble the patterns. —description from the designer
