The Free Virtual-Coin Demo
Twelve independent fair bits are sampled once and revealed one per second. Four consecutive blocks of three bits represent four basins. Terminal reward 1 requires EACH block to contain both 0 and 1; any 000 or 111 block loses. Initial success(6/8)^4=81/256. Quote=0.97×exact conditional success probability÷(81/256), which may rise or fall. A successful full sequence pays 3.06567901235×; auto 5 cannot trigger. Collect initially at 0.97 or after a revealed bit, or preselect auto 1.2/1.5/2/3/5. First upward crossing pays the full actual quote. A fully known bad block makes zero immediately; bit 12 settles automatically. Two equal uint 32 buckets give unbiased bits; no hidden rerolls or randomness during pricing. Every revealed-information stopping policy has 97% expected gross return, not 97%win probability or a guarantee. One captured stake 10/20/50/100; settings and refill locked while playing. Wallet and fractional credits persist after reload. Idle balance below 10 can be restored to exactly 1,000 free coins.
