    "theme": "East-Asian / Chinese garden fantasy. A red-lacquered wooden temple gate frames the reel grid, set inside a glowing jade-green circular moon-gate archway. Behind the archway is a soft-focus bamboo forest with green paper lanterns glowing at the base. The cast is a group of cute animal characters (panda, monkey, peacock, a purple-maned orange boar/ox-like creature) styled as bamboo-forest guardians, plus stylised Chinese playing-card suits (club/heart/spade/diamond) each carrying one of the four classical elements as a kanji character (fire, water, earth, wind).",

Character portraits are bust-style icons in square ornate gold/copper frames, drawn in a cute, rounded, mascot/chibi-adjacent style (large heads, simplified friendly faces) typical of casual mobile-slot art. Palette is bright and saturated: jade/teal greens, warm gold and copper metals, red lacquer, with a gentle daylight/dusk misty-forest mood (soft haze, glowing rim light around the moon-gate) rather than a dark or neon look. Camera angle on the reel grid is a straight-on, static front view (no isometric or top-down perspective); win/feature banners use a slightly theatrical spotlight glow behind bold 3D beveled lettering.",

A doubled-total-bet scaling test (tiers double when Total Bet is doubled) was deliberately NOT used as proof, because with a fixed 50-line grid a doubled total bet also doubles the implied per-line stake, so that test cannot distinguish the two hypotheses (per-line vs total-bet basis) - it only proves the payout SCALE is linear, not which basis it is linear in."

It is unclear from the captured frames alone whether '7' was a transient digit mid-way through a spinning reveal animation (most likely, per the paytable's own description of the Bonus Symbol Trigger as something that 'spins to determine and award' the amount) or a separate, different value - the confirmed final award, per free_spins_awarded.png ('YOU HAVE BEEN AWARDED 6'), was 6 Free Spins.",

This is flagged rather than a number invented to fill the gap.",
