Neutral Adjacent Swaps: App Download and Browser Demo

The "Neutral Adjacent Swaps" game is fully functional in this browser demo. You do not need to download an APK file to play. The demo runs directly in your web browser and does not require an installed app package.

While an app may exist, this guide has not verified an official app package. A search result or a similarly named domain does not confirm that an app is the official source. The browser demo is self-contained and does not rely on an external installation.

"Neutral Adjacent Swaps" uses a specific set of rules defined by the contract. Each entire eight-code word is equally likely among 65,536 words.

• Objective: Count unequal adjacent position pairs whose swap preserves the number of maximal equal-code runs.
• Score Function: Gross = 0.96 × captured whole stake × raw^(selected mode + 1) / mean[selected mode].
• Mode Normalizers: Separate exact means are [2.15625, 6.732421875, 25.365966796875].
• Expected Gross Return: 96%. This is not a guarantee of net profit.

Powers one, two, and three do not alter which raw scores are zero. The game features eight practice deliveries, not a standard six-ball over. Shot0..3 before each delivery permutes an independent uniform hidden code; displayed runs are 0, 1, 2, 4.

The demo supports three separately normalized score powers. You can choose between manual and automatic play.

• Manual Play: Advances through all eight deliveries. Shot choice may change between deliveries.
• Auto10: Queues whole matches.
• Stop: Cancels future rounds only. The current automated match completes before stopping.

During a captured match, stake, payout mode, and refill are locked. Sound remains available throughout. One whole captured stake is used; there are no independent row shares.

The demo uses a virtual wallet with specific persistence rules. The initial balance is 1000 virtual coins.

• Restoration: A manual idle-only restoration sets the balance to exactly 1000. This is eligible while idle and when the balance is below 10.
• Fractional Carry: Persists across settlement, refill, and reload.
• Settled Balance: Persists locally, including zero.
• Unfinished Round: If you reload during an unfinished round, it ends without refund or resume.

This is a local simulation. There is no account login flow or payment processing in the demo.

The following table shows the measured RTP from simulation. These are supporting observations, not the exact mathematical law.

The listed simulation tests used different shot policies. In the playable demo, payout mode selects the score power; it does not select a shot policy.

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; this is not a claim that other requests or processing are absent.

The intended audience for this guide is 18+. This is a guide policy, not a claim about local law or an implemented age gate. The demo does not process personal data through an account system.
