Legendary Chest Rarity Ladder
A result-first arcade chest animation resets to common, climbs through rarities, then lands on a three-reward reveal.
Starter prompt / by Refs
The creator shared no short prompt. This is ours for making a film like it with Claude.
Stage a loot-box reward screen for a casual game in one HTML file, using three.js for a glossy 3D treasure chest and HTML/CSS for the interface. The pink-and-gold chest drops onto a glowing pedestal, rattles and bursts open in light rays, sparkles and flying coins; then three reward cards flip in, coins, gems and a new crown item, with counters ticking up, and a chunky Collect button pulses. Use a bold rounded display font, add synthesized chimes, and record 15 seconds at 1920×1080.
Field notes / why it works
The first frame gives away the open legendary chest, then the 0.5-second reset creates anticipation for the upgrade path. A stable centered chest moves from common to rare at 2.25 seconds and epic at 4.15 seconds through colour and light, before three specific reward cards arrive around 12 seconds.
Plate 01 / The format in one breath
A playful game reward screen flashes the top prize immediately, resets to a basic chest, then upgrades through increasingly valuable chests before revealing three rewards. The viewer gets the outcome in frame one and stays for the animated route back to it.
Why it works
- At 0:00, the open gold-and-pink chest and large “LEGENDARY CHEST” headline give the payoff before any setup; at 0:00.50, the scene resets and creates a reason to watch the climb.
- One centered chest and glowing floor ring remain recognizable across common, rare and epic states (0:00.75, 0:02.60, 0:04.40); changing colour and light communicates progress without new scenery.
- At about 0:12, three reward cards turn the light show into countable prizes: +1,420 coins, +46 gems and one crown. The “COLLECT” button gives the sequence a clear finish.
