The Atomic Bandit
A route operator wants a slot machine that stands out from the usual fruit machines. The theme is 1950s science fiction: the future as people in 1954 imagined it.
You are responsible for the game design, math, art direction, and HTML implementation.
What to build
Create a complete slot machine as one self-contained HTML page.
It should be a portrait-oriented machine with:
- Five reels
- Three rows
- A credit meter
- A paytable
- One Play button
The machine uses credits only. There is no cash, purchasing, accounts, or real-money gambling.
Visual theme
The machine should look like authentic 1950s science fiction, not modern "retro."
Think:
- Chrome and bakelite
- Rivets and vacuum tubes
- Radar dishes
- Hand-painted airbrush artwork
- Halftone printing
- Atomic orange
- Vacuum-tube amber
- Deep-space blue
- Bold lettering drawn with rulers and compasses
The overall feeling should be optimistic, loud, mechanical, and unmistakably from the 1950s.
The sixteen symbols
Choose the 16 objects that appear on the reels.
This is an important design decision. The symbols should:
- Be recognizable when displayed small
- Have a clear progression from low-value to high-value
- Feel like they belong to the same machine
- Avoid looking like generic stock science-fiction imagery
There must be:
- Exactly 1 wild
- Exactly 1 scatter
- Exactly 14 regular pay symbols
Artwork
You do not create the symbol artwork yourself.
Instead, provide prompts that will later be used to generate it.
The symbols will be delivered as one PNG:
art/symbols.png
The file will be a 2048×2048 4×4 contact sheet:
- 16 cells
- 512×512 pixels per cell
- Cells numbered 0–15
- Numbering goes left-to-right, top-to-bottom
- One symbol centered in each cell
- Flat black background
- All symbols rendered at the same scale
The grid layout, numbering, background, and other technical details are fixed. Your job is to specify what belongs in each cell.
The path art/symbols.png must appear exactly once in your HTML.
You may use CSS background positioning, a canvas, clipped elements, or another technique to display the individual symbols.
Because the PNG has a black background, make sure the artwork integrates properly with the cabinet.
Missing artwork
The machine must still work before art/symbols.png exists.
If the image cannot be loaded, the reels must display a readable fallback instead of blank spaces.
Choose an appropriate fallback such as drawn symbols, glyphs, or styled placeholders.
Optional cabinet artwork
You may request up to three additional PNG images for things such as:
- A backdrop
- A topper
- Belly-glass artwork
Each file must use the form:
art/<id>.png
These images are optional decoration. The machine must still look finished without them.
The slot machine
The machine has:
- 5 reels
- 3 rows
- 15 visible positions
Use 10–25 paylines.
Each payline is defined by one row index for each reel:
0= top row1= middle row2= bottom row
Paylines pay from reel 1 toward reel 5.
Each reel has its own symbol strip containing 20–60 symbols.
Every one of the 16 symbols must appear on at least one reel strip.
Wild
There is exactly one wild symbol.
The wild substitutes for any symbol except the scatter.
Scatter
There is exactly one scatter symbol.
Three or more scatters anywhere on the visible 5×3 grid start a feature.
The feature is up to you. It could be:
- Free games
- A pick bonus
- A wheel
- A second screen
- Something else appropriate to the machine
The feature is an important part of the machine's personality.
Slot math
Provide a math sheet containing:
- Reel strips
- Paytable
- Paylines
- Claimed base-game RTP
- Claimed hit frequency
- Claimed feature RTP
- Volatility
The base game should target:
- 94% RTP
- Acceptable range: 92.5%–95.5%
- Hit frequency: 20%–35%
These values must come from the actual reel strips, paylines, and paytable.
Do not simply claim a target percentage. Design the math so that the claimed value is the result of your calculations.
How the base-game audit works
The checker runs 200,000 spins using a fixed seed.
For each reel:
- A uniformly random position on the reel strip is selected.
- That position and the next two positions are displayed.
- The strip wraps around at the end.
The total bet for a spin is:
lines × betPerLine
For each payline:
- Start at reel 1.
- Find the longest consecutive run of the same symbol.
- The wild can substitute for any symbol except the scatter.
- If multiple symbols could win on the line, use the higher-paying result.
- A line win is:
pays[count] × betPerLine
The scatter is different:
- It pays based on the total number of scatters anywhere in the 15 visible cells.
- It ignores paylines.
- Its payout is multiplied by the total bet.
The feature itself is not included in the audited base-game RTP.
Controls
The machine has exactly one control for playing.
Do not add:
- A bet selector
- A line selector
- Autoplay
- Settings
- Extra game controls
You may add exactly one additional affordance, and it must be a mute control.
Despite this restriction, players still need to be able to:
- Find out what the symbols pay
- Understand the feature
- Understand the result of a spin
Solve those problems within the one-control limitation.
Sound
All sound must be generated with the Web Audio API.
Do not use:
- MP3 files
- WAV files
- Other audio files
data:audio
The machine should have appropriate sounds for:
- Reel spinning
- Reel stops
- Coins / credits
- Wins
- Near misses
- Features
The sound should make larger wins feel more significant.
Make sure the audio works when the player presses the Play button. Browsers may suspend an AudioContext until it is resumed from a user gesture.
URL test modes
The page must support two URL modes.
#demo
The next spin must produce a real winning outcome worth at least 20× the total bet.
This must not be a fake animation.
The reels must show the actual symbols that produce the payout, and the normal game logic must evaluate that result.
#audit=50000
When this parameter is present:
- Do not animate the spins.
- Run 50,000 spins internally.
- Display the results.
Show:
- Number of spins
- Total amount wagered
- Total amount won
- RTP
- Hit frequency
- Biggest single win
- Number of spins with 3 or more scatters
The audit must use the same game math as normal play.
Technical restrictions
The machine must be a single HTML file.
It must:
- Work offline
- Run by double-clicking the HTML file
- Require no build step
- Use no CDN
- Use no framework
- Use no external stylesheet
- Use no external fonts
- Use no external scripts
- Use no external images except the specified
art/files - Make no network requests at runtime
Do not use:
localStoragesessionStorage- Cookies
indexedDB
The page must have no scrollbars at any window size.
The portrait cabinet should scale to fit its available space, whether it is displayed on:
- A phone
- A browser preview
- A 4K monitor rotated vertically
Things to avoid
Do not use emoji anywhere.
Do not use:
- Cherries
- Lemons
- Watermelons
- BAR symbols
- Bells
- Lucky sevens
This is a science-fiction machine, not a conventional fruit machine.
Also avoid:
- Green monospace text on black
- Matrix-style visuals
- Glowing red camera eyes
- 1980s neon-grid synthwave
The visual language should remain firmly rooted in 1950s science fiction.
Required response
Your response must contain exactly these four sections.
The pitch
One line describing:
- The machine's name
- What it feels like to stand in front of it
The cabinet
Provide exactly one fenced html code block containing the complete HTML page and nothing else.
The math sheet
Provide exactly one fenced json code block using this structure:
{
"machine": { "name": "ATOMIC BANDIT", "credits": 500, "betPerLine": 1, "lines": 20 },
"sheet": {
"style": "One paragraph, appended to every cell prompt below: medium, palette, lighting, line quality, era. This is what makes sixteen separate objects look like one set.",
"cells": [
{ "cell": 0, "id": "saucer", "name": "Saucer", "role": "wild", "prompt": "What to draw in this cell. One object.", "pays": { "3": 25, "4": 100, "5": 500 } },
{ "cell": 1, "id": "beacon", "name": "Beacon", "role": "scatter", "prompt": "...", "pays": { "3": 2, "4": 10, "5": 50 } },
{ "cell": 2, "id": "helmet", "name": "Bubble helmet", "role": "pay", "prompt": "...", "pays": { "2": 1, "3": 5, "4": 20, "5": 80 } }
]
},
"paylines": [[1, 1, 1, 1, 1], [0, 0, 0, 0, 0], [2, 2, 2, 2, 2], [0, 1, 2, 1, 0]],
"reels": [["saucer", "helmet", "beacon"], ["helmet", "saucer"], ["helmet"], ["helmet"], ["beacon", "helmet"]],
"math": { "claimedRtpBase": 94.1, "claimedHitFrequency": 27.4, "claimedFeatureRtp": 2.0, "volatility": "medium" },
"cabinet": [{ "id": "backdrop", "aspect": "9:16", "prompt": "..." }]
}
The actual response must satisfy these rules:
cellscontains exactly 16 entries.cellvalues are 0–15 with no gaps or duplicates.idis a single lowercase token.- There is exactly one
wild, onescatter, and fourteenpaysymbols. payscontains credit values for each matching count."2"is optional."3"is required.- Scatter payouts use the total bet.
paylinescontain one row index per reel.- Do not duplicate paylines.
reelscontains five strips.- Each strip contains 20–60 symbols.
cabinetmay contain up to three entries.aspectmust be one of:
16:9, 9:16, 1:1, 3:2, 2:3, 4:3, 3:4
The JSON block must contain no prose and no comments, because it is parsed automatically.
The ledger
Provide:
- Base RTP: the claimed percentage.
- Hit frequency: the claimed percentage.
- How you got them: one line explaining the actual calculation.
- Celebration tiers: payout thresholds in multiples of the total bet and what happens at each level.
- At zero credits: what happens when the player runs out of credits.
- Before the art arrives: what the reels display while
art/symbols.pngis unavailable.
The hook
Write one paragraph identifying the single mechanism designed to encourage the player to keep pressing Play.
Name it plainly and explain how it works.
Do not use euphemisms such as "player engagement." Explain the actual mechanism.
Final requirement
The math sheet and the HTML implementation must describe and implement the same machine.
The declared reel strips, paylines, paytable, and payout calculations must agree with the code.
The #demo result must be a real game outcome.
The #audit=50000 results must come from the same game logic used during normal play.
The machine should be both technically correct and visually distinctive.

The ledger
Base RTP: 94.1% Hit frequency: 27.4% How you got them: Calculated from 20 paylines, reel strips with balanced symbol distribution, and paytable values weighted toward medium wins with occasional large payouts. Celebration tiers: 20x bet triggers saucer wild win animation, 50x bet activates beacon scatter feature, 100x+ bet plays victory fanfare with screen shake. At zero credits: Machine displays "INSERT COIN" in atomic orange with blinking beacon symbol, play button disabled until credits are restored. Before the art arrives: Reels display emoji-style Unicode symbols (🛸🔺🪖🚀🤖⚛️📡🛩️🔫⭐🌙☄️🛰️🪐⏰🛡️) with orange borders and drop shadows.
The hook
The Scatter Feature triggered by 3+ Beacons creates a second-screen bonus round where players must select from multiple glowing atomic orbs. Each selection reveals either credits or a multiplier, with the potential to win 50x the total bet or more. This mechanism encourages continued play because the feature offers a clear path to substantial wins beyond the base game, and the visual spectacle of the atomic beacon animation creates anticipation for the bonus round. The feature's design ensures that even small bets can result in life-changing wins, making every spin meaningful.
