Tobias Halloran

Tobias is the last pair of eyes on every page. He compares each number, rule and feature description with the game itself and its provider's documentation, and sends back anything that cannot be traced to a source.

What I Verify on Every Page

Six areas are checked on every page before it is published, and again whenever a game or its rules change.

01

Return to player

The default RTP, any alternative settings and the RTP of optional features such as bonus buys.

02

Volatility and hit rate

Ratings are taken from the game where it shows them, not from third-party summaries.

03

Paytable values

Symbol pays are recalculated as multiples of the stake and compared with the in-game table.

04

Feature rules

Triggers, retriggers, multipliers, meters and caps are checked against the written rules and the demo.

05

Stakes and limits

Minimum and maximum bets and the maximum win are confirmed, including how the cap ends a round.

06

Player safety wording

Age limits, demo disclaimers and support contacts are checked for accuracy and clarity.

Why checking matters

Numbers Travel Faster Than Corrections

Slot data is copied constantly. A volatility rating, an RTP figure or a feature description gets repeated from one listing to the next, and a single early mistake can end up on dozens of pages. I started fact-checking game content after years in data quality work for a sports statistics company in Leeds, where one wrong figure could spread through every product that used it.

My approach is deliberately dull. Every figure on a page needs a source, preferably the game's own information screens or the provider's documentation. If two sources disagree, the game wins. If the game does not show a figure, the page says so instead of guessing. That rule has caught more than one confident claim about volatility or retriggers that turned out to be wrong.

I also read every page as a player would. Does the text explain the conditions attached to a big number? Does it make clear that a demo result predicts nothing? Is the responsible play advice specific enough to use? A page can be accurate and still misleading, and catching that is part of the job.

When sources disagree, the game's own information pages decide.

Workflow

From Draft to Published

Source list

The author supplies a source for every figure and rule in the draft.

Independent check

Each item is verified against the game and the provider, without relying on the author's notes.

Corrections

Anything unconfirmed is rewritten, softened or removed, and the reasons are logged.

Sign-off and updates

The page is approved for publishing and re-checked whenever the game or its rules change.
