The Beginner level has one 5x5 grid, Intermediate has two 6圆 grids, and Advanced has four 8x8 grids to solve per game (Shamrocks, hearts, smiley faces or gumdrops). As the skill level progresses, the game becomes timed, the grid size increases, and more similar pictures are used. The object is to clear the tableau in the fewest turns. Purble Pairs is a pattern recognition and memory game similar to Concentration. The collection has a single home screen that offers three packs of games: Purble Pairs, Comfy Cakes, and Purble Shop. Purble Place was publicly introduced in Windows Vista build 5219, along with Chess Titans and Mahjong Titans.
