Iara Bittencourt
Iara Bittencourt is the author of the 389wincasino.com guides. She writes about slots, crash games and, above all, the gap between what a promotion advertises and what its terms actually say. Her work is turning bonus terms, game info panels and payment rules into calculations anyone can redo with a calculator.
Focus
Three subjects run through her writing: slot mechanics (ways to win, cascades, Hold & Win, free spins, bonus buys), crash-game maths (the rising multiplier, auto cash-out, why no strategy beats RTP) and the real cost of bonuses. The comparison between clearing the same wagering on a 96.75% slot and on a 94.03% one, on our wagering page, is hers.
Method
- Source first. Game data appears only when independent sources agree; everything else becomes "check the game panel".
- Contract before advert. Every bonus guide starts from the terms: multiplier, base, deadline, max bet, contribution and cashout cap.
- Show the working. Every calculation lists the numbers used and is labelled illustrative.
- Verify, do not vouch. Licences are something readers check in public registers; the guides explain how.
What she does not write
You will not find "hot hours", "guaranteed strategies", promises of winnings or player testimonials in her guides. Nor will you find operator claims that cannot be checked — minimums, payout times, bonus percentages or licence conditions stay with the cashier, the terms and official sources. When data does not exist, the text says so plainly, as on the game pages without public specs.
Responsible gambling as part of the method
Explaining the maths is also a form of protection: someone who understands that RTP is an average cost and that high volatility needs a bigger bankroll tends to set more realistic limits. That is why every guide points to responsible gambling and to free support such as Gambling Therapy when play stops being fun.
How a guide gets written
A typical guide starts with the primary material: the promotion terms, the game's rules screen or the payment provider's own documentation. The next step is separating facts that can be confirmed from claims that cannot; only the first group goes into the text as fact. Then come the worked examples, built with round, clearly invented numbers so readers can swap in the figures from their own account. The last pass checks the page against our editorial rules: no promises, no invented operator figures, a responsible-gambling link, and a plain statement wherever data is missing.
