Four-Bit Digit Distance
Digit Bit Difference 2D draws one uniform integer from 00 through 99. Express its tens and units digits as four-bit binary codes. The score counts positions where those codes differ. Choose target distance zero through four before drawing; all matching numbers are highlighted, with no individual additions or removals. Example 12 gives 0001 and 0010, distance two; 69 gives 0110 and 1001, distance four. Number 00 has distance zero. This original demo uses no external feed, forecast or real draw schedule.
Target distances zero, one, two, three and four cover respectively 10,30,36,20 and4 of the100 equally likely numbers. Every target is nonempty. N is the count of covered outcomes and hit probability is N/100. Distance four covers only69,78,87 and96. Starting deducts one captured stake and locks distance, stake and restoration until settlement. A match credits captured stake multiplied by96/N, including the original stake in the gross credit; do not add that stake again. A miss credits zero. There is no interim collection or second charge. Each result is independent of earlier draws.
Five Exact Coverage Sets
Target distances zero, one, two, three and four cover respectively 10,30,36,20 and4 of the100 equally likely numbers. Every target is nonempty. N is the count of covered outcomes and hit probability is N/100. Distance four covers only69,78,87 and96.
One Captured Stake and Final Settlement
Starting deducts one captured stake and locks distance, stake and restoration until settlement. A match credits captured stake multiplied by96/N, including the original stake in the gross credit; do not add that stake again. A miss credits zero. There is no interim collection or second charge. Each result is independent of earlier draws.
Virtual Wallet and Restoration
A new local wallet starts with 1000 virtual coins. Stakes are 10, 20, 50 or 100, initially 20. One draw costs one captured stake. While idle with a balance strictly below 10, manual restoration sets the wallet to exactly 1000, rather than adding 1000. Fractional payout carry remains separately saved. Restoration and settings are disabled during a draw. These counters have no cash value, prize or withdrawal route.
The settled wallet, including a zero balance, and fractional payout carry persist in this browser’s localStorage. Reloading ends an unfinished round without refund or continuation. A different browser, device or cleared site storage can have different saved counters. Clearing cached files alone may leave localStorage intact. The local wallet is not an operator account or synchronised financial balance.
Frequently asked questions
Is an operator verified?
TDA7388 is a search label, not an operator identity established by this guide. tda7388.info is an independent information guide with its own Digit Bit Difference 2D demo. No company, licence, official account domain, commercial game catalogue, payment service, app publisher or support contact is verified here. Search position, a similar name and page appearance cannot establish those facts.
How is four-bit distance counted?
Digit Bit Difference 2D draws one uniform integer from 00 through 99. Express its tens and units digits as four-bit binary codes. The score counts positions where those codes differ. Choose target distance zero through four before drawing; all matching numbers are highlighted, with no individual additions or removals. Example 12 gives 0001 and 0010, distance two; 69 gives 0110 and 1001, distance four. Number 00 has distance zero. This original demo uses no external feed, forecast or real draw schedule.
Which numbers does the selected distance cover?
Target distances zero, one, two, three and four cover respectively 10,30,36,20 and4 of the100 equally likely numbers. Every target is nonempty. N is the count of covered outcomes and hit probability is N/100. Distance four covers only69,78,87 and96.
