Session Report TCHW-20260729-01: One Thunder Coins: Hold and Win Run, Published in Full
Below sits the complete record of TCHW-20260729-01, one logged demo session of Thunder Coins: Hold and Win: 2,960 spins at a flat 1.00 stake, the checkpoints read from the ledger, the feature rounds it produced, and the arithmetic that ties a 80.0% return to a closing balance anyone can check.
The session is published whole, the good stretches and the flat ones together, because a run is only evidence if all of it is on the record.
What these numbers are, and what they are not
Session passport
The arithmetic that has to close
The publishing test does not care how the session felt: the start, minus everything staked, plus everything returned, must equal the final balance on the screen.
It closes to the cent, which is the standard every session on this site has to meet before a single number leaves it.
Balance curve, read from the ledger
The curve traces the recorded balance across the run at even intervals, plus the start and the close; it does not interpolate between readings. The dotted line marks the 11,000.00 start. The session ran between a high of 11,022.00 and a low of 10,406.00, both read from the full ledger.
Corrected 9 September 2026: the high and low above are now taken from the full ledger. The first version of this page quoted the extremes of the plotted sample, which fell short of the checkpoint table's own peak.

How this was logged
One sitting on 29 July 2026, launched from the same in-page link the demo shelf uses. The balance was recorded continuously, a timestamped frame of the screen was kept throughout, and after the close the totals were rebuilt from the recorded spins and set against the on-screen final; the invariant section shows the result. The stake held flat at 1.00 for the whole run, so every figure here is a clean read at one bet size. The full protocol lives on the methodology page.
