Terms and Mechanics for Deletion Echo Demo

Deletion Echo uses eight fair binary symbols. The game automatically evaluates deleting each of the seven adjacent two-symbol blocks. The score is based on unordered pairs of deletion positions that yield identical six-symbol results.

A single whole captured stake covers this complete independent fair binary word. You can choose between three score modes: score, score squared, or score cubed. Each mode is separately normalized over all 256 equally likely words to an expected gross return of 96%. Using a larger power does not change which words score zero.

The gross payout is calculated as: Gross = 0.96 × captured whole stake × raw^(selected mode + 1) / mean[selected mode]. The expected gross return is 96%; this is not a guaranteed net profit for any session.

The demo allows for Auto10, which queues at most ten captured draws. The Stop function cancels future draws while the current one settles. There is no early bank option.

Settings, stake, and refill are locked until settlement and the queue finish. The settlement takes 480ms. During active settlement and the auto queue, controls are locked, but sound remains available.

The wallet balance persists locally, including zero balances after settlement. If you reload the page during an unfinished draw, the round ends without refund or resume.

Restoration: You can manually restore the balance only when idle and the balance is below 10. This action sets the balance to exactly 1000 and preserves fractional carry. Fractional carry persists across settlement, refill, and reload. This is not automatic replenishment or adding coins.

This demo uses browser localStorage for the settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet; actual browser request capture is pending.

The absence of account or payment controls in the demo does not prove that no personal data are processed. There is no demo account flow or payment flow.

The intended audience for this guide is 18+. This is a policy statement and not a claim about local law or an implemented age gate. Responsible-use pages can describe optional pauses, a personal time/virtual-coin limit, and finding appropriate local qualified help. The demo does not clinically train behavior or make losses safe.

Simulation measurements are supporting sample observations, not the mathematical payout law. The exact expected gross RTP is 0.96 for all modes. Measured RTP from 1,000,000 rounds varies slightly:

• Power 1: Measured 96.1366035139576%
• Power 2: Measured 96.22067018206963%
• Power 3: Measured 95.94080361771411%

Worked examples from the pure score function show that ordered symbols like [0,0,0,0,0,0,0,0], [1,1,1,1,1,1,1,1], and [0,1,0,1,0,1,0,1] all yield a raw score of 21.
