Casino Bankroll Management: Blackjack, Slots and Roulette
How to size your casino bankroll honestly per game — what house edge actually means for blackjack, slots and roulette, and how to track win/loss truthfully.
Casino games aren't beatable in the long run for most players. That doesn't mean bankroll management is pointless — it means it's about controlling how much you lose and how often, not whether you lose.
House edge translated to dollars
House edge × bets per hour × average bet = expected loss per hour.
- Blackjack (basic strategy): 0.5% × 60 hands/hr × $25 = $7.50/hr
- American roulette: 5.26% × 40 spins/hr × $25 = $52/hr
- Slots (typical): 5–10% × 600 spins/hr × $1 = $30–60/hr
The "cheap" game is whichever one you play with discipline. Slots are slow per spin but fast per dollar.
Bankroll rule per game
- Blackjack: 40× average bet for a session. Long sessions, small bets.
- Roulette / craps: 20× average bet, short sessions, walk away on a stop-loss.
- Slots: Set a hard ticket budget. Don't reload.
Why "I broke even" is a lie
Memory is selective. Players remember big wins, forget small losses. The only honest way to know your real result is to log every session — buy-in, cash-out, game, venue, time. Over 50 sessions the truth is usually 30–60% worse than your gut estimate.
Track it like a poker player
The same discipline that makes poker bankroll management work makes casino tracking work:
- Log every session in 15 seconds (Balnceo's quick-add does this for casino games too)
- Tag by game and venue
- Review monthly
- Adjust budget or game selection based on data, not feelings
You won't beat the house. You will stop being surprised by your annual loss.
