Block Stack: Line Clear

Smiley Cube Pop is a vibrant casual match blast puzzle game with cute cartoon smile face cubes.
Tap any group of 2 or more adjacent same-color smiley blocks to eliminate them and gain points. Special rainbow star cubes appear randomly on the grid; tapping them triggers massive full-screen cube explosions for huge score bonuses.
Three bright cube colors are available: yellow, pink and blue, each printed with a soft cheerful smile pattern. A progress track bar sits at the top to display stage advancement, with a pause button in the top-right corner. A red helper bubble button in the bottom-right offers extra elimination assists during tough levels.
No move limits or strict timers, players can take their time to find large connected cube combos for higher point multipliers. Warm soft color palette and adorable block design create light, joyful casual gameplay for all ages.
