Stack.it is a 2048 merging game that features stacks of vibrant, candy-colored, irregular round shapes labeled with numbers instead of sliding tiles or cubes. It displays a 3x3 board with nine pink-and-white tiles. The shapes on the tiles slide up, down, left and right. When the player slides one shape toward a single identical shape or a stack of shapes with the match on top of the stack, the shape leaps or flips onto its match to form a new shape labeled with the sum of the numbers.
The player's primary goal is to repeatedly stack identical shapes to merge them and create higher-numbered, larger shapes. Two tiny 2 shapes, for example, merge to become a 4 shape. The player can stack smaller shapes on larger ones, but not larger ones on smaller ones. They can also prompt two shapes to stack on top of a third one. Although their goal is to reach 2048, they can play beyond that number to attempt to go as high as 32K.
Since the shapes in Stack.it can jump two tile spaces onto a third tile and all shapes slide at the same time if empty spaces or merge possibilities exist, the player must use common sense and strategic thinking before they slide the shapes. If they don't take care, they can accidentally fill the board with non-matching shapes and run out of moves. If they keep the board open, they can eventually make 15 merges with only one move and create a 10-shape stack.
