An Android gamified educational quiz app screen captured on a compact phone mockup, bright and playful. The background is a vivid electric blue (#1A56F0) with cloud-like soft white shapes at the corners for visual texture. At the top: a header strip showing a flame streak icon with "Streak: 7 days" in bold white, a lightning bolt icon with XP counter "1,240 XP" in amber, and a heart row showing 3 filled hearts (lives) in red. Below a thin progress bar (filled 60% in lime green), a question card floats in white with 20px corners: the question text reads "Which planet has the most moons?" in 20px Nunito Semibold dark blue. Four answer option buttons are stacked: large rounded rectangles, each in a slightly different tonal blue — A) Saturn, B) Jupiter, C) Uranus, D) Neptune — in 18px white text; option B is highlighted in a brighter teal indicating selection. An animated confetti burst graphic appears in the upper-right to suggest a correct answer celebration. At the bottom: a "Continue" button in vivid lime green rounded rectangle. Color palette: electric blue, lime green, amber, white, red hearts. Typography: Nunito. Mood: energetic, encouraging, kid-friendly.
