Nature of the Site and Demo Game
Twelve independent fair samples −1/+1 are drawn once and revealed one per second. For zero-based index i, alternate coefficient(+1,−1,+1,−1,…). Terminal reward=[sum((-1)^i×sample_i)]². This is not ordinary endpoint displacement. All+1 gives alternating sum 0 and reward 0; alternating+1/−1 gives sum 12 and reward 144. Initial expected reward 12 over 4096 paths. After k reveals with partial alternating sum s, quote=0.97×(s²+12−k)÷12. It may rise or fall. Initial quote 0.97, maximum 11.64. Collect after any reveal or initially; preselect auto 1.2/1.5/2/3/5. First upward crossing pays the full actual quote, even when later hidden samples would end at zero. Conditional zero is possible only at complete 12 with sum 0; final 12 settles automatically. Two equal uint 32 buckets sample unbiased signs; no hidden rerolls or randomness while quoting. 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 active. Wallet and fractional credits persist after reload. Idle balance below 10 can be restored to exactly 1,000 free coins.
Eligibility and Responsible Play
Set a session timer and virtual-coin limit before starting, and stop when either is reached. Do not chase losses or treat a favourable result as an income forecast. Free coins do not turn the simulator into training for guaranteed real-money success. If play interferes with daily activities or feels difficult to control, close the game and seek support from a qualified local health professional or a trusted person.
