Methuselah's

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a playable browser slot-machine game titled “METHUSELAH’S: ONE MORE HIT EDITION,” presented as a fictional, no-real-money arcade gambling prototype. Use a full-screen 3D Three.js background: the interior of a dark double-wide trailer with an oil-stained dark floor, ribbed metal back wall with rusty vertical ribs, low ceiling, two hanging iron chain columns near the sides, three faulty cyan fluorescent tubes overhead, and a glowing blue rectangular neon sign/light on the rear wall. Light the room with animated cyan and magenta point lights plus a flickering overhead light; add subtle fog, a very slow camera sway, and a grimy neon-noir atmosphere. In front of this, center a large responsive HUD machine panel with a thin cyan border, dark translucent gradient, inner cyan/magenta glow, scanline texture, and fluorescent/glitch styling. Use a monospaced techno font and high-contrast cyan, hot pink, pale yellow, green, and blue neon accents.

The main machine header has small cyan text “TRAILER PARK ARCANE,” a large pale-yellow glowing “METHUSELAH’S” title, and pink subtitle “ONE MORE HIT EDITION.” On the right show three digital meters labeled BAL, BET, and WIN, initially BAL 001000, BET 000010, WIN 000000. Under the header display a centered status/alert line, initially “20 LINES // FICTIONAL CREDITS // NO REAL MONEY.”

Build a 5-column by 3-row slot grid, with narrow Greek-key decorative side columns. Each cell is a dark inset tile with a subtle cyan border, a large glowing procedural text/vector icon, and a small symbol name label. Symbols and their visual colors are: WILD (gold star), MEDUSA (cyan symbol), AMPHORA (violet), CRYSTAL (bright cyan diamond), FLAME (orange), VIAL (green), SPOON (silver), MASK (purple), PROPANE (tan), and SCATTER (pale yellow; render its icon as a small wave/wing-like mark). The initial visible grid may be WILD, MEDUSA, PROPANE, CRYSTAL, SCATTER / CRYSTAL, FLAME, VIAL, WILD, AMPHORA / PROPANE, MASK, SPOON, MEDUSA, CRYSTAL. Add animated reel blur while spinning, pulsing highlights around winning cells, scanlines over the reel area, and a “GLITCH MODE” overlay with chromatic-offset text and shaking panel when glitch mode activates.

Implement exactly 20 fixed paylines across the 5 columns, including horizontal top/middle/bottom lines and zigzag/diagonal patterns. Each spin deducts the current bet from the fictional balance, uses a deterministic seeded random generator based on a timestamp and spin count, and chooses three vertically adjacent symbols from weighted per-column reel strips. The bet starts at 10 and can be adjusted from 10 to 100 in increments of 10. WILD substitutes for all non-scatter symbols on paylines. Evaluate left-to-right paylines for 3, 4, or 5 matching symbols, with the symbol payout hierarchy: WILD 50/250/1200, MEDUSA 40/180/900, AMPHORA 28/90/420, CRYSTAL 24/80/360, FLAME 18/60/260, VIAL 14/44/190, SPOON 10/28/120, MASK 8/22/90, PROPANE 6/18/70; scale payouts by bet/10. SCATTER pays anywhere, with 3/4/5 scatters paying 20/90/500 scaled by bet/10.

When 3 or more MEDUSA symbols appear anywhere, activate Glitch Mode: forcibly replace 2–4 randomly selected cells that are neither SCATTER nor MEDUSA with WILD before evaluating the result, show the glitch overlay, shake the machine, and announce that Medusa broke the grid and a wild swap was forced. If at least two scatters are visible, show an anticipation phase before evaluation. Use staged status messages such as REQUESTING_SPIN, REELS_STARTING, ANTICIPATION, EVALUATING, WIN_PRESENTATION, and IDLE, with messages about balance deduction, reels tearing through static, paylines checking, and no hit.

Below the reels, provide five controls: BET -, AUTO, a large glowing blue circular/pill SPIN button, TURBO, and BET +. SPIN is also activated by Space or Enter; TURBO toggles faster reel and payout animations with an active bright-green/cyan appearance and is also toggled with T; AUTO toggles automatic spinning and is also toggled with A. Disable spin/bet controls while a spin is resolving, and prevent spins when the fictional balance is below the bet. Add simple synthesized arcade audio on user interaction: reel tones, bass thumps for anticipation/gamble, a hiss for glitch or bust, and brighter notes for wins.

After any win, present a centered dark overlay panel asking “LEFT OR RIGHT?” with a lightning-bolt/Zeus icon, LEFT and RIGHT green buttons, a gold COLLECT button, and a “LADDER 0/5” readout. The player can choose Left or Right, also using ArrowLeft/ArrowRight, for a deterministic 50/50 double-or-nothing gamble. Each successful step doubles the current win and advances the ladder, up to five steps; the player may collect instead. A loss forfeits the gambled win and returns to idle. After five consecutive gamble busts, enter a desaturated “REHAB MODE”: show a gray panel titled REHAB MODE explaining that high-risk features are locked and the player must take a guaranteed PITY SPIN to restore the neon. PITY SPIN costs nothing, guarantees three CRYSTAL symbols on the middle row, then completes rehab and restores normal styling. While in rehab, disable normal spin/bet/auto features.

Include a rare idle-only Tweak-Out event: roughly a 10% periodic check every five seconds, excluding auto and rehab, drains a small fictional amount (half the bet, minimum 1) from the balance with a glitch effect and status text about fictional credits leaking. Make clear visually and in messages that all credits are fictional. Add a small footer showing the current phase and a changing seed readout. Ensure the layout is responsive and mobile-safe, with large touch targets, no page scrolling, and pointer/touch controls alongside keyboard shortcuts. There should be no external image assets; icons are procedural Unicode/text/vector-style symbols.
