| Most "side bets" at any table | 5% – 35% | varies | Side bets exist because the math is bad. That's the only reason. |
SET A LOSS LIMIT BEFORE YOU SIT DOWN
Decide what you can lose tonight without it affecting your week. That number is your stop-loss. When you hit it, you walk. The house's only weapon is your inability to leave when you're losing — take that weapon away and the math doesn't matter.
BET SIZING IS YOUR REAL EDGE
You don't beat the house edge with a system — you survive it long enough to enjoy variance. Bet 1-2% of your session bankroll per hand. $200 night = $2-4 a hand. Sounds small. The reason your friend who "got crushed" got crushed is they were betting $25 a hand on a $200 bankroll. Eight bad hands and they're done.
NEVER CHASE LOSSES
"I'll double up next hand to break even" is the single most expensive sentence in any casino. The cards don't know you're stuck. Each hand is independent. Doubling because you're behind is exactly how a $200 night becomes a $2,000 night.
"HOT" AND "COLD" ARE NOT REAL
Slots don't get hot. Tables don't run cold. The wheel has no memory. Streaks happen because variance produces clustered runs of independent events that look patterned to the human brain — but the next spin's probability is the same as the first one's. The gambler's fallacy is the most expensive cognitive bias on the casino floor.
