Intro to Gamicard

TL;DR Gamicard is a provably‑fair, on‑chain scratch‑card game on Aptos that awards instant APT prizes, fuels a rolling multi‑tier Jackpot, runs a monthly Grand Giveaway (GA), and grants loyalty points for every play.

What is Gamicard?

Gamicard turns the familiar fun of scratch cards into a transparent, on‑chain game built on Aptos. Each purchase mints a card‑NFT, you scratch a 5×5 icon grid, and instantly see what you win: APT prizes, Jackpot hits, Grand Giveaway raffle tickets, and Points.

Why it matters

• Provably fair: Deterministic mapping from on‑chain randomness to outcomes; anyone can recompute the reveal off‑chain using the seed and block refs.

• Transparent economy: Clear fund split per purchase; auditable pools; jackpot and GA mechanics are fully documented.

• Frictionless UX: A Delegator Account lets you open many cards with a single signature while keeping custody of your wallet.

Key entities

• Card tiers (price in APT): Fortune (0.5 APT), Prosperity (1 APT), Abundance (5 APT).

• Pools: Card‑Reward Pools (per tier), Jackpot Pool (global), Grand Giveaway Pool, Referral Pool, Protocol Revenue.

• Assets: APT (prizes), Card NFTs (one per purchased card), Raffle Tickets (for GA), Points (for loyalty & rewards).

Fairness overview

1. Draw random seed on‑chain.

2. Deterministically map seed → grid icons, jackpot icon flag, ticket flag, points.

3. Persist outcome on‑chain with proofs (txn hash/seed) so anyone can re‑verify.

“Sure‑Win” principle

Every card always yields something positive:

• an APT payout, or/and

• a Grand Giveaway ticket, and/or

• Points (redeemable for future benefits).
