1. Pick a target. Any multiplier from 1.01× up. Win chance = 99 ÷ target, so a 2.00× target wins 49.5% of the time and a 100× target wins 0.99% of the time — the 99 is 100 minus the 1% house edge.
2. Beat the climb. Each bet draws a result multiplier that counts up from 1.00×. If it stops at or above your target, you win bet × target. Below it, the bet is lost.
3. Demo first, on-chain later. This build lets anyone open the page, connect Phantom, see a real balance, and stress-test the game loop with demo SOL before any program is deployed. Betting never touches real SOL in phase 1.
Phase 2 — full on-chain. Next step after testing: an Anchor program with a house vault, bet instructions that lock SOL, and verifiable randomness / seed commitments settled on-chain. Then this same UI switches from demo balance to real devnet bets, then mainnet — and shared chat and real deposits/withdrawals unlock with it.
⚠️ This is a testing front-end, not financial advice and not a live casino. Don't send real SOL to any address shown here for betting in phase 1. This page never asks for your seed phrase.
