Stake idle LUMY in a 5-second crash round. Cash out above 2.00× and the vault hands you a Mystery Box with an AI-forged collectible — redeemable for real perks on Nordtrust.
No purchase, no cash-in, no cash-out. LUMY is a non-withdrawable in-app social currency earned inside Swipix. Rewards are promotional, have no cash value and are subject to terms. Demo build — balances are simulated and no production account is touched.
——0—crash = max(1.00, ⌊(1−0.05)/(1−r)×100⌋/100), r = first 52 bits of HMAC-SHA256(serverSeed, clientSeed:nonce). The hash above is committed before the round; the seed is revealed on session end, so every round is recomputable.
LUMY has no cash value and cannot be withdrawn or purchased. Caps: 20 rounds & 3 boxes per day, 60 s cool-down after 5 losses.
Every artwork in this build was generated by gemini-3-pro-image from the prompt stored on the card back. No text is baked into the art — titles, rarity and utility are rendered by the app, which keeps the deck localisable.
Cryptocurrency trading involves risk. Past performance does not guarantee future results. Bonuses are promotional, capped and subject to terms. Demo build: the exchange call is mocked — the payload shape matches the Phase-1 contract in TZ.md §7.
Swipix mints LUMY for uploads and referrals but has almost no place to spend it, and Nordtrust needs qualified crypto-curious sign-ups. One mini-app solves both: it burns the soft currency through a habit loop whose terminal reward is a reason to open an exchange account.
Push + an unopened-box badge. Quiet-hours aware, 1/day cap, existing CRM exclusion gates.
A 5-second provably-fair crash round. The stake is LUMY — never DOPPY, never cash.
Above 2.00× the vault opens. Rarity is the variable schedule; a pity timer stops tilt.
Burn 3 → 1 tier up. Utilities activate on Nordtrust, which is the actual conversion.
