Math Game Rewards Spiral Into Bonus-Mode Chaos
A portrait arithmetic-game playthrough turns each correct answer into a larger celebration, ending with a frantic bonus round and a 180-point result.

Design a playful arithmetic quiz game for children called {APP_NAME} as a single HTML file in portrait 430×860, with a round pastel mascot, chunky rounded buttons and a grid-paper background. Every correct answer earns points and a celebration bigger than the last: sparkles, then confetti, screen shake, rainbow text and fireworks, until a perfect score unlocks a frantic bonus round. Add synthesized chimes and fanfares, then script an automatic play-through and record about 50 seconds with headless Chrome and ffmpeg.Field notes / why it works
The menu establishes the game in 1.4 seconds, and a correct answer produces an outsized points jump by about 0:03. Reward layers build through the 100-point celebration at 0:22, then seven compact bonus tasks keep refreshing the screen until the 180-point result at 0:51. The stable problem card and keypad keep the action understandable despite the growing visual noise.
Plate 01 / The format in one breath
A direct recording of a cute, portrait learning game. The viewer watches simple answers trigger increasingly oversized rewards, then a perfect-score gate opens a faster bonus mode. The promise is visual rather than spoken: every correct action makes the screen more celebratory.
Why it works
- The first 1.4 seconds give a clear title, mascot, difficulty choice, and start button; the game is understandable before play begins.
- A restrained first answer at about 0:02 grows into ribbons and extra characters by 0:09, a large 100-point celebration at 0:22, and a bonus-mode banner at 0:28.
- The score closes twice: a 100-point result around 0:25, then a higher 180-point result at 0:51. Those visible numbers make the escalation measurable.
Plate 02 / Format card
| Platform · aspect · length | X · 430×860 (1:2 portrait) · 53.4 s · 30 fps |
| Pace | 14 measured shots, 13 cuts, 14.6 cuts/min; 9 uncertain fast changes put the possible ceiling at 24.7 cuts/min. Mean shot 3.81 s, median 2.79 s. |

| Voice | None. |
| On screen | 100% captured or rendered game interface; no presenter or external b-roll. |
