What the two logs say together, and what it means for anyone who plays: How to win on pokies: what 1 million real spins say.
Where the data comes from
Each story starts from a CSV export of a single account's betting history, the same table an operator keeps for its own accounting: one row per spin, with the time, the game, the stake, the payout and the balance after the round. The exports were provided to us with the account holder's consent, on the condition that the player is not identified. Before analysis we remove everything that could identify a person: account numbers, usernames, e-mail addresses, IP addresses, device details and the operator's internal IDs. What remains is the spin-level record and nothing else.
The aggregates behind every chart are downloadable as CSV from each story (marked as Download the data), under a CC BY 4.0 licence with attribution to toponlinecasinoaustralia.com. We do not publish raw rows. The charts and tables on each page are aggregates: results by day or by month, balance by the hour, the share of bets at each size, the net result by game.
How the numbers are calculated
- Player result = payouts − stakes, over any period. A negative number is money the player lost to the games; it is the operator's gross win from that account.
- Turnover is the sum of all stakes. It is much larger than the money deposited, because winnings are re-bet many times.
- Deposits and withdrawals are not in a bet log. We reconstruct them from gaps between the balance after one spin and the balance before the next: a jump up is a deposit or bonus, a drop is a withdrawal. These are estimates and are labelled as such.
- Time stamps are taken as exported. The time zone is usually the operator's, not the player's, so times of day are approximate.
- Cancelled rounds (a stake refunded with no result) are excluded from bet counts and results.
What we do not do
We do not describe a player's emotions, motives, finances outside the account, or anything else the table cannot show. We do not present any pattern in the data as a strategy: every story in this series ends with less money than it started with, and the big wins in them arrived on the same bets, in the same games, at the same rhythm as the thousands of spins that paid nothing. We do not identify the operator when doing so could identify the player.
