Overlap Circuit is an original browser simulator with free virtual coins and no cash redemption. Its mathematical checks apply to this demo only. They do not authenticate an outside company or demonstrate that any commercial game has the same rules.
Four distinct positions and any closed ordering
Twelve independent fair bits form four consecutive three-bit blocks. The entire twelve-bit outcome is sampled once and revealed automatically, one bit per step. Each block has three bits, not twelve. Players do not choose bits or arrange the blocks manually.
Terminal raw reward is one if some permutation of all four block positions forms a closed directed ring: every block’s final two bits match its successor’s first two bits, including the closing link. Otherwise reward is zero. Equal-valued blocks remain distinct positions and each position must be used once. This is an existence test, not a count of matching links or valid orders.
What Pakistani Players Should Check Before Playing
For readers in Pakistan, the key is understanding that VD89 offers a free demo with virtual coins, not real money gaming. While the site may list prices or points, these are not necessarily linked to Pakistani Rupees (PKR). You must verify if the operator accepts PKR directly or if conversions apply. Common local payment methods like JazzCash and Easypaisa are widely used in Pakistan for digital transactions, but you should CHECK with the operator to see if they support these specific wallets for any future features. Always look for a "Payment Methods" or "Banking" section on their site to confirm availability.
Regulation-wise, gambling is restricted by national law in Pakistan, with some exceptions for lotteries and horse racing. Since VD89 is an independent demo, it may operate in a grey area. For safety, check the footer for a license number and verify it with the relevant authority. Use a secure browser and clear your cookies after playing. Remember, this is a demo with virtual coins, so no real winnings are guaranteed or payable.
- Check if JazzCash or Easypaisa are listed as supported options.
- Verify the license number in the website footer.
- Confirm that the game uses virtual coins only, not real PKR.
80 successful complete words and conditional quote
Exactly 80 of the 4,096 equally likely complete words satisfy the ring test. Initial mean raw reward is 80/4,096 = 0.01953125. Quote = 0.97 × exact conditional expected terminal reward / that mean. It uses revealed bits and every possible hidden suffix; no hidden future bit enters the visible quote. It starts at 0.97× and may rise, fall or reach zero.
The expected gross return is 97% for policies based only on revealed information in this fair model, not a 97% win chance, optimal puzzle skill or guaranteed session result. Zero ends immediately. A positive final quote settles automatically. A successful complete word quotes 49.664×. No second 3% factor is applied.
Permutations, repeated positions and closure
The complete word 001100010000 gives blocks 001, 100, 010, 000. Their original order fails, but positions 1→3→2→4→1 give 001→010→100→000→001, satisfying every two-bit overlap. Thus its raw reward is one. The engine finds this order automatically.
Four separate 000 blocks also succeed: identical values still occupy four positions. Three 000 blocks and one 111 block cannot form a valid closed ring, so 000000000111 rewards zero. A matching chain without its final closing link is insufficient. Completing a circuit is not required to collect an earlier positive conditional quote.
Manual collection and the first full Auto crossing
Before starting choose stake 10, 20, 50 or 100 and Manual or Auto threshold 1.2×, 1.5×, 2×, 3× or 5×. Those settings and one stake are captured. Settings and refill lock while active. Auto is a collection threshold, not repeated-round play. Reduced motion changes timing only.
Manual Collect first processes all reveals due at the current timestamp. Due reveals are processed in order, so an earlier Auto crossing pays its entire actual quote before later events. Zero before crossing loses; an unreachable crossing is not itself a loss if the final quote is positive. All offered thresholds are below the possible maximum 49.664×.
Manual refill below ten coins
A new local wallet starts at 1,000 free coins. The balance and fractional payout carry are stored in this browser’s localStorage. Whole coins are credited from each payout while its fractional remainder carries forward. They have no cash value.
Refill is manual and available only while idle with a balance below 10. It sets the balance to 1,000 rather than adding 1,000, and preserves fractional carry. It is neither a timed refill nor a reset available during a round. No promo code or deposit is involved.
Settled wallet persistence and interrupted rounds
Reload normally reads the stored balance and fractional carry. A deducted stake is already part of that balance. An unfinished round is not resumed or refunded on reload; do not close the page expecting it to recover an animation.
Clearing this site’s stored data can remove the wallet. Clearing cached images alone need not clear localStorage. Storage can also be unavailable or restricted by browser settings. This local wallet is not a cross-device account.
Frequently asked questions
Does the name establish an operator?
VD89 is a search reference in this independent guide. It does not establish a verified publisher, official domain, licence, app, support channel or payment service. The guide does not authenticate an outside operator or conclude that absence from an unspecified list proves fraud. Overlap Circuit is an original browser simulator with free virtual coins and no cash redemption. Its mathematical checks apply to this demo only. They do not authenticate an outside company or demonstrate that any commercial game has the same rules.
Must the original block order work?
Twelve independent fair bits form four consecutive three-bit blocks. The entire twelve-bit outcome is sampled once and revealed automatically, one bit per step. Each block has three bits, not twelve. Players do not choose bits or arrange the blocks manually. Terminal raw reward is one if some permutation of all four block positions forms a closed directed ring: every block’s final two bits match its successor’s first two bits, including the closing link. Otherwise reward is zero. Equal-valued blocks remain distinct positions and each position must be used once. This is an existence test, not a count of matching links or valid orders.
How is the quote priced?
Exactly 80 of the 4,096 equally likely complete words satisfy the ring test. Initial mean raw reward is 80/4,096 = 0.01953125. Quote = 0.97 × exact conditional expected terminal reward / that mean. It uses revealed bits and every possible hidden suffix; no hidden future bit enters the visible quote. It starts at 0.97× and may rise, fall or reach zero. The expected gross return is 97% for policies based only on revealed information in this fair model, not a 97% win chance, optimal puzzle skill or guaranteed session result. Zero ends immediately. A positive final quote settles automatically. A successful complete word quotes 49.664×. No second 3% factor is applied.
Do identical blocks stay distinct?
The complete word 001100010000 gives blocks 001, 100, 010, 000. Their original order fails, but positions 1→3→2→4→1 give 001→010→100→000→001, satisfying every two-bit overlap. Thus its raw reward is one. The engine finds this order automatically. Four separate 000 blocks also succeed: identical values still occupy four positions. Three 000 blocks and one 111 block cannot form a valid closed ring, so 000000000111 rewards zero. A matching chain without its final closing link is insufficient. Completing a circuit is not required to collect an earlier positive conditional quote.
Does Auto pay its threshold or the actual quote?
Before starting choose stake 10, 20, 50 or 100 and Manual or Auto threshold 1.2×, 1.5×, 2×, 3× or 5×. Those settings and one stake are captured. Settings and refill lock while active. Auto is a collection threshold, not repeated-round play. Reduced motion changes timing only. Manual Collect first processes all reveals due at the current timestamp. Due reveals are processed in order, so an earlier Auto crossing pays its entire actual quote before later events. Zero before crossing loses; an unreachable crossing is not itself a loss if the final quote is positive. All offered thresholds are below the possible maximum 49.664×.
Does VD89 pay out in Pakistani Rupees (PKR)?
This is a free demo with virtual coins. It does not involve real money payouts in PKR. Always CHECK the operator's terms to confirm if any virtual credits can be converted, though typically demo games do not.
Can I use JazzCash or Easypaisa on VD89?
These are common local payment methods in Pakistan. However, you must CHECK the VD89 website directly to see if they currently support JazzCash or Easypaisa for any specific features, as this is not confirmed by this independent guide.
