What Indian Players Should Check
Before engaging with the i77 Neutral Adjacent Swaps demo, Indian users must verify a few key details directly with the operator. First, confirm whether the platform supports the Indian rupee (INR) for its virtual coin system, as this affects how you perceive value. Second, check which payment methods are accepted if you decide to buy more virtual coins later. Common options in India include UPI, Paytm, and PhonePe, but availability varies by operator and region.
Regulatory compliance is also crucial. Gambling laws differ by state in India, so ensure that playing this demo game is permitted in your jurisdiction. For safety, always download the APK only from the official i77 website or verified app stores to avoid malware. Keep your device's storage clear for smooth performance and check the privacy policy to understand how your data is handled.
- Verify INR support and accepted payment gateways.

Game Rules and Mechanics
"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.
Controls and Modes
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.
Wallet and Persistence
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.
Mathematical Evidence
The following table shows the measured RTP from simulation. These are supporting observations, not the exact mathematical law.
| Mode | Exact Gross RTP | Measured RTP | Positive Results |
|---|---|---|---|
| 0 | 0.96 | 95.96286886956523 | 884,078 |
| 1 | 0.96 | 95.92462682680592 | 884,160 |
| 2 | 0.96 | 96.03439898455231 | 883,443 |
Shot policies vary by mode: Mode 0 uses always-zero; Mode 1 uses delivery-index-mod-four; Mode 2 uses adaptive-previous-outcome-plus-delivery-mod-four.
