Spent three months tracking every single gambling session. Time of day, game choice, bet sizes, win/loss amounts, even my mood before starting. Fifty sessions total with detailed notes.
The data revealed patterns I never expected. Turns out I wasn’t losing because of bad luck or rigged games—I was losing because of specific, predictable circumstances I kept repeating.
SpinPirate Casino UK became my testing ground with 11,000+ slots from 150 providers and instant Bitcoin withdrawals. Their GBP 20 minimum deposits and crypto options let me run controlled experiments without massive bankroll requirements across different game types.

What I Tracked (And Why)
Each session got logged in a spreadsheet:
- Start time and end time
- Game(s) played
- Starting bankroll
- Final balance
- Biggest win and biggest loss
- Number of bonus rounds triggered
- My mental state (1-10 scale for focus and stress)
Took about two minutes to log everything after each session. Small effort that revealed massive patterns.
The Worst Time: Late Night Sessions
Sessions starting after 10 PM lost money 82% of the time. Average loss: $147 per session.
Sessions starting between 2-6 PM? Lost money 54% of the time. Average loss: $73.
The difference was brutal. Late night gambling destroyed my bankroll consistently.
Why this happened: I was tired, making worse decisions, chasing losses harder, and playing longer than planned. The data doesn’t lie—my win rate tanked after 10 PM every single time.
The “Just One More Bonus” Trap
Sessions where I hit a bonus in the first 20 spins had an 89% loss rate. That shocked me.
You’d think hitting a bonus early means good luck. Nope. What happened was this: early bonus got me excited, I increased bet sizes, kept playing way longer than planned, and gave everything back plus more.
Sessions with no bonus in the first 50 spins had a 48% loss rate. Much better.
The lesson: Early wins made me reckless. Starting slow and grinding made me more careful.
Weekend vs Weekday Gambling
Weekend sessions (Saturday-Sunday) lost $4,200 total across 18 sessions. Average loss per weekend session: $233.
Weekday sessions (Monday-Friday) lost $2,800 total across 32 sessions. Average loss per weekday session: $87.
Weekends crushed me. Probably because I had more free time, played longer, and treated it like “entertainment” instead of controlled sessions.
The Games That Hurt Most
High volatility slots murdered my bankroll. Sessions focused on high volatility games lost money 76% of the time.
Medium volatility sessions? Lost 51% of the time—basically a coin flip.
Testing classic games like da vinci diamonds demo slot first showed me baseline volatility patterns before risking real money. That 2011 IGT game has predictable medium volatility that helped me understand what sustainable gameplay feels like.
Crypto vs Fiat Sessions
This one surprised me. Sessions using Bitcoin and other cryptocurrencies lost money 71% of the time.
Fiat sessions lost 58% of the time.
Why? Crypto made it too easy to deposit instantly. No waiting period, no friction. When I was losing with fiat, bank transfer delays forced me to stop. With crypto, I could reload in 30 seconds and keep playing.
Sessions at platforms offering the best crypto slots showed this pattern clearly—instant deposits removed natural stopping points that usually saved me from bigger losses.
Bet Size Patterns
Sessions where I increased bets mid-session lost 84% of the time. Sessions where I kept bets flat lost 49% of the time.
The math is obvious: betting progression during losses accelerated bankroll death. But I kept doing it anyway until the data showed how destructive it was.
The Mood Factor
Sessions where I rated my mood 6 or below (stressed, tired, frustrated) lost money 79% of the time.
Sessions where I rated my mood 8+ (focused, relaxed, clear-headed) lost money 43% of the time.
Mood wasn’t everything, but it mattered way more than I thought. Playing while stressed basically guaranteed losses.
What Changed After Tracking
I stopped gambling after 9 PM entirely. That single rule cut my average losses by 40%.
I quit increasing bet sizes mid-session. Saved another 25% on average losses.
I started testing games in demo mode first, especially high volatility slots. Filtered out 60% of games that would’ve eaten my bankroll.
I also stopped weekend marathon sessions. Limited myself to 45-minute weekday sessions only.
The Data Doesn’t Lie
Fifty sessions revealed the truth: I wasn’t unlucky. I was gambling at the worst possible times, with the worst possible mental states, using the worst possible bet management.
Fixing those patterns didn’t make me a winner, but it cut my losses by more than half. Sometimes that’s the only win that matters.
