Slots vs blackjack — which is actually killing my bankroll faster?

[roulette rick77]

Did the math on my 2025 sessions because I had a feeling. I split my play between roulette (my main thing), slots, and occasional blackjack. Of those three my blackjack sessions are net positive on the year (+$280 across 47 sessions, basic strategy, mostly low-deck count games). Slots are -$2,140 across 89 sessions. Roulette is essentially neutral (-$60).

Theoretical RTP says slots at 96% and blackjack at 99.5% basic strategy should be roughly aligned with this result. But the spread is wider than the theoretical math suggests because slot volatility eats your bankroll in chunks while blackjack drips small losses you can survive longer.

Reposting this because I changed where I play after running the numbers — moved my blackjack sessions to Slots.lv (oddly, their blackjack tables have the best rules I've found in their software stack) and reduced my slot volume by half. Curious if anyone else has tracked this kind of cross-game P&L.

My data is the opposite shape. 2025: slots +$1,400, blackjack -$280, roulette -$420. But I think it's variance not strategy — I had two slot wins above $800 each that swing the sample. If you exclude those my slots P&L is -$190 which lines up with theoretical.

Sample size matters a lot. 47 blackjack sessions isn't enough to confirm a 99.5% RTP — variance can easily produce +$280 on negative-EV sessions in that volume.

Roulette being neutral on the year at -$60 sounds suspicious to me — at 2.7% house edge on European you should be down somewhere between 1.5% and 4% of your turnover depending on bet sizing. Are you betting flat or are you using a progression system?

If you're not using a progression and you're actually neutral on a few hundred sessions, you might want to log your wheel — could be a positional bias if it's the same software wheel that's not been audited recently.
