The interaction begins with a tap on a pulsing free gift icon, triggering a 3D purple gift box to scale up and bounce in the center of the screen with colorful fireworks. The box lid pops open, releasing rewards (money, dice, pickaxes) that fly upwards and explode into a screen-filling cascade of stylized 3D assets. Following this, a golden sticker pack slides up, opens, and reveals three collectible cards one by one with a scaling flip animation. Finally, tapping the 'Collect' button shrinks the cards and flies them into the album icon in the bottom right corner with a fast, curved trajectory.
