Where limits are shown
Most blackjack tables display a sign near the dealer stating the minimum and maximum bet. The minimum is the smallest wager accepted on a spot for a hand, and the maximum is the largest. A table might show a range such as a low minimum and a maximum many times higher, though the actual values vary widely between casinos, cities and times of day.
Limits apply per betting spot, and a player who plays several spots at once must meet the minimum on each. The details are in the discussion of multi hand play. Limits can also change during the day. A table may open at a lower minimum in a quiet period and raise it when the room fills.
Some tables show the key rules on the same sign, such as the natural payout, the dealer’s soft 17 rule and the number of decks. The posted rules matter as much as the limits, since they affect the house edge.
Why casinos set limits
Minimums serve a business purpose. A table needs a dealer, floor supervision and floor space, and the casino expects a certain amount of betting to cover those costs. A busy table at a higher minimum earns more per hour than a slower one at a low minimum.
Maximums protect the casino from very large swings. Because outcomes vary, a single large bet could lose more than the casino wants to risk on one hand. A cap keeps the variance manageable. The reasoning is the same as the idea behind the risk of ruin, applied from the casino’s side: even a game with an edge can produce losing runs, and a cap limits how costly those runs can be.
Maximums also limit certain betting patterns. Strategies that rely on repeatedly doubling a bet after a loss run into the cap quickly, and they cannot make an unfavourable game favourable in any case. The mathematics behind this is addressed in the piece on betting systems, and nothing about a limit guarantees a way to win.
What limits signal
A table’s limits tell you a few things, though never everything.
- Stakes and clientele. Low minimums usually attract casual and newer players, and high minimums attract players willing to risk more per hand. The social atmosphere can differ as a result.
- Game pace. Low-limit tables are often crowded, so fewer hands are dealt per hour, while high-limit tables, with fewer players, may deal quickly.
- Rule quality. There is no reliable link between limits and fairness of rules. A higher minimum does not mean a better game. Some low-limit tables use less favourable payouts, such as 6 to 5 on naturals, and some higher-limit tables may offer better rules, but you have to check the table rather than assume. The difference between payouts is covered under natural payouts.
- Surveillance and supervision. Higher-limit tables may be watched more closely, simply because more money is on the table.
Limits are not a sign that a table is “hot” or “cold” either. There is no evidence that any table is more likely to favour players, a point also made in the discussion of hot tables.
Limits, session length and cost
The minimum bet sets a floor on how much you will wager. A simple illustration helps. Suppose a table deals about 60 hands an hour, and you bet the minimum each hand. At a minimum of 10 units, you wager 600 units an hour in total. At a minimum of 25 units, you wager 1,500 units an hour. The amounts wagered are the product of minimum and hands, 60 × 10 = 600 and 60 × 25 = 1,500. These are not what you lose, just the total amount bet. The long-run cost is a small percentage of that, determined by the house edge, which is why the same session length costs more at the higher limit. More detail on estimating this is in the article on cost per hour.
Short-term results can be much larger or smaller than the average, so a minimum that looks affordable over an hour may be too high for a longer session. As a rule of thumb, choose a table where the minimum bet is a small fraction of the money you set aside for the session. That way, a few losing hands in a row do not end the session. The reasoning is in the article on setting a session budget, and any amount you set aside should be money you can afford to lose.
Some practical points
- Check the sign before you sit. If you buy in and then discover the minimum is higher than you expected, you will either play bigger than planned or have to leave.
- Know the buy-in expectations. Some tables expect a minimum buy-in, typically linked to the posted minimum.
- Betting above the maximum. The floor supervisor sometimes has authority to approve a higher bet for particular players, but this is at the casino’s discretion and should not be expected.
- Do not raise your stakes to recover losses. Moving to a higher limit after a bad run is a common way for losses to grow. Past hands do not change future odds, and chasing losses is mathematically futile.
