Three rows and five ordered digrams per row
One spin draws three independent rows. Each row contains six independent symbols uniformly chosen from zero, one and two. Each six-symbol row has five overlapping ordered adjacent pairs, at positions0-1,1-2,2-3,3-4 and4-5.
The raw row score counts equal unordered pairs of these five digrams: compare all ten pairs of digram positions i less than j. Overlapping occurrences count. Within a digram, symbol order matters:01 and 10 are different. A single repeated symbol is not itself the scoring object. Each row uses one third of the captured total stake and their gross returns add.
Check overlapping occurrences and pair counts
The row 000000 has five identical00 digrams, so all ten unordered pairs match and raw score is ten. The row 012012 has digrams 01,12,20,01,12; the two 01 occurrences give one match and the two12 occurrences another, scoring two.
The row 012210 has digrams 01,12,22,21,10. All five are distinct, so its raw score is zero despite the repeated single symbol2. Counting only adjacent digram matches would miss valid matches at separated positions. Counting reversed pairs as equal would also change the rule incorrectly.
Exact 729-pattern means and one-third row shares
Each row has 729 equally likely ordered symbol sequences. Choose Low, Medium or High before spinning. Positive raw row scores receive square-root, identity or square weighting respectively; zero remains zero. These are weights, not final payout multipliers.
For each mode calculate its exact mean weight over all 729 row sequences, including zero scores. Each row credits one third of the captured total stake times0.96 times its weight divided by that mean. Add all three gross row credits. Every mode has 96% exact expected gross virtual return.
The stake was deducted before settlement, so gross return is not net profit. Modes change positive payout sizes after separate normalisation but leave positive-score frequency unchanged. Neither 96% nor a matching digram guarantees a session balance or describes a 96% winning probability. Digram positions within a row overlap; their comparisons are not independent coin flips.
Captured rounds and the persisted wallet
A new browser wallet starts with 1,000 free virtual coins. Settled balance and fractional-credit carry persist in localStorage. Reload does not replenish settled funds. Fractional row returns accumulate before whole coins are credited rather than being separately discarded.
A spin captures one total stake and one mode for all three rows. Settings and refill lock during settlement and an active automatic queue. Auto runs at most ten rounds; Stop prevents future rounds while an already active spin settles. Optional free refill is available only while idle with balance below ten. It sets balance to 1,000 and preserves fractional carry. Coins cannot be bought, transferred, redeemed or withdrawn.
Local storage and third-party requests
Browser localStorage keeps the settled virtual balance and fractional-credit carry. Pages request Google Fonts and a Statinside analytics script. Hosting, CDN and third-party requests may expose IP address, browser, device, path and request details. No anonymity, particular retention period, cookie lifetime or complete processing profile is established.
This guide has no registration or identity-document form. That does not mean browsing produces no personal data or that records cannot be linked to someone. Cache clearing alone may leave localStorage intact. Removing site data can erase the wallet without deleting requests or records already held elsewhere. Free refill changes local game state; it is not a data-deletion tool.

Digram Echo calculations concern only this browser simulator. Playing it cannot test a commercial platform, device, app or transaction.

Frequently asked questions
Does this guide represent a manufacturer or casino?
No. It supplies its own browser simulator and authenticates no external business or affiliation.
How many digrams are in a six-symbol row?
Five ordered adjacent pairs, from positions0-1 through4-5, including overlapping pairs.
How is the row score counted?
Compare all ten unordered pairs of digram positions and count the pairs containing equal ordered digrams.
Are 01 and 10 the same digram?
No. The order of symbols within each digram matters.
What is the score of 000000?
Ten: its five00 digrams form ten equal unordered pairs.
Why does 012012 score two?
It contains two 01 digrams and two12 digrams. Each duplicate type contributes one equal pair.
Can a repeated single symbol still give score zero?
Yes. In 012210 the five digrams 01,12,22,21,10 are distinct, so the score is zero.
How many equally likely row sequences exist?
729, from three independent uniform symbol choices at each of six positions.
Does every row use a full separate stake?
No. Each independent row uses one third of the captured total stake; their gross returns add.
Do modes change positive-score frequency?
No. They change positive weights after separate normalisation and preserve zero and positivity.
Does 96% guarantee a winning chance or session balance?
No. It is exact expected gross virtual return per stake in this simulator model.
What do Stop and refill do?
Stop prevents future auto rounds while the active round settles. Manual refill only while idle below ten sets balance to 1,000 and preserves carry.
