Jackpot System

• Contribution & threshold

  • 5% of every purchase goes to the global Jackpot Pool.

  • Jackpot icons will only appear when the pool balance is ≥ 1,000 APT.

  • Max one jackpot icon can appear on a single card.

  Odds & tiers

  • All three tiers fund the same jackpot, but higher‑priced cards have higher odds to getting a jackpot icon. Intuition: a 5 APT card proportionally increases the chance vs a 0.5 APT card, aligning icon appearance rate with contribution size.

  • Exact odds are calibrated to keep jackpot emission (expected payout rate) within target bounds while maintaining excitement. The relationship is monotonic with price; jackpot odds do not affect non‑jackpot payouts.

  Prize categories (split of current pool)

  • Diamond (Primary) → 80% of the pool.

  • Gold (Secondary) → 15%.

  • Silver (Tertiary) → 5%.
