Session Report LAVB-20260730-01: One Lava Balls Run, Checkpoints and Bonus Rounds
Every review on this portal closes with a session ID and one promise: the session log is available on request. This page puts one session's checkpoint record in the open, so the promise can be inspected rather than taken on trust. Below is the checkpoint record of LAVB-20260730-01, the run behind our Lava Balls review: 2,975 spins, 27 balance checkpoints, all 21 bonus rounds, five frames from the archive and the arithmetic that ties it together.
The tables print every checkpoint and every bonus round exactly as the session log recorded them, and the figures match the review to the cent. If a number on this page ever disagrees with the review, one of them is wrong, and the contact form is the right place to say so.
What these numbers are, and what they are not
Session passport
The arithmetic that has to close
One equation decides whether a session may be published at all: the starting balance, minus everything staked, plus everything returned, must equal the final balance on screen, to the cent.
Here it closes exactly. When it refuses to close, the session is discarded and run again; no number on this portal comes from a session that failed the check.
Balance curve across 27 checkpoints
The curve connects the 27 checkpoint values from the table below; it does not interpolate the spins between them. The dotted line marks the $100,000.00 start.
Checkpoint table, in full
Checkpoints are fixed at session milestones. The first spin, one peak, three scheduled midpoints, one close and the 21 round openings make the 27 rows. A round row shows the balance once the triggering spin's stake had left it, before the round paid; the first row shows the balance once the first stake had left it; every other row shows the balance once the listed spin had settled.

Corrected 18 September 2026: the first row is labelled by what it shows, the balance once the first stake had left it. Trigger spins in the round table are now counted the way the checkpoint table counts them, by the spin whose stake opened the round; the first version of this page ran one spin ahead. No payout or total changed.
Balances are read from the session log at the moment each checkpoint was fixed. Each checkpoint also stores its own frame; five of them are printed further down.
Bonus registry, all 21 rounds
Every free-spins round the session hit, in order. No selection, no highlights reel. Lava Balls pays a round out as one collect at its close, so the payout column is the whole round, retriggers included.

Round payout is the amount the round put back on the balance at collect, read straight from the balance ledger. Each figure is checked against the checkpoint curve above; round 3 is the jump between checkpoints 4 and 5.
The 21 rounds returned $3,353.28 between them, 62% of everything the session paid back; the base game contributed $2,037.12 across the same 2,975 spins. The split closes its own equation too: $2,037.12 + $3,353.28 = $5,390.40 returned.
Five frames from the archive
The archive behind this session holds 13,374 timestamped frames. These five sit at the moments the tables above describe.
How this was logged
The run took one sitting on 30 July 2026, 3 hours 53 minutes at a flat $2.00 stake, launched from the same link the demo shelf uses. The balance was fixed at every checkpoint listed above, and the archive kept a timestamped frame of the screen through the whole run. 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 full protocol, including the rule that a failed reconciliation kills the session, lives on the methodology page.
The spin-by-spin log behind this page is not printed here; it is retained, and it is available on request through the contact form, as is the log of any other published session: name the game and the session ID, say where the figures will appear, and link back to the report when you publish them.
Relabelled 16 September 2026: the title and the opening of this page used to say "published in full" and "complete record". They now say what the page holds, the checkpoint record and the bonus register, and where the rest is. No figure changed.
Where these numbers live
The review takes its headline figures straight from this log: the 90.59% observed return, the 32.47% hit frequency and the 708.92x best full round. They sit in context in the Lava Balls review, next to the paytable on the Lava Balls rules page. For why a session figure may sit six points under the printed one, read observed vs stated RTP; for what return figures mean at all, start with what RTP actually is.
