Press the screen to begin stacking emojis. Watch the moving emoji to align with the stack below. Press again to drop the emoji onto the stack. Target to align the emoji perfectly with the one below to create a taller stack. Steer clear of misalignment, as it will reduce the stack and make it smaller. Move forward through a variety of levels by assembling emojis as high as possible. Be mindful of the increasing speed as you advance to higher levels. Perfect your timing to reach the highest stack and conquer all levels.
