Cube Merge Challenge

Step into a minimalist dice tile puzzle built around rotation placement and dual-attribute merging rules. Every new tile stack spawns at the screen bottom, with a rotation function to spin the entire group 90 degrees and adjust its shape before dragging it onto the open grid canvas. Once placed, all unbroken horizontal or vertical connected clusters of three or more tiles that share identical color and equal dot counts will fuse together, forming a single tile with an elevated dot value. To trigger a merge, tiles must match both shade and dot quantity, adding a unique layer of logical planning absent from standard single-condition match puzzles. Three separate tile variants populate the board: gray single-dot, yellow two-dot, green three-dot, each with bold black dot markers for instant visual identification. Essential status readouts line the top edge of the display: your live running score updates after every successful merge, alongside your historical highest score benchmark and a simple pause control in the top-right corner for mid-game breaks. The uniform blank grid background minimizes visual fatigue during long play sessions, with soft colored dice tiles that create gentle contrast against empty cells. Difficulty rises naturally as you fill more grid cells with placed tiles, shrinking available placement space and requiring precise tile rotation and positioning to form qualifying three-piece matching clusters. No timers or speed-based obstacles disrupt gameplay, giving you unlimited planning time to rotate each incoming tile stack, arrange it on the grid, and build large dual-match clusters that upgrade into higher dot value dice tiles.
