The question of bringing a blackjack chart to a casino has no universal yes or no answer, because it is governed by the individual property's table-game policy rather than by any single rule of blackjack itself. Some venues permit printed basic strategy cards at the table, some prohibit them outright, and others allow them only under specific conditions such as being kept off the table surface. This article explains the mechanism behind those policies and where the authoritative current answer lives.
What a reader can take from this article is the structure of the decision and the channel for confirming it. What this article cannot provide is a venue-by-venue list of permissions, because no such list exists in a stable, publicly verifiable form. Policies change, and the only source that binds is the property where you intend to play.
Why a chart is a policy question, not a game question
Blackjack basic strategy charts are reference documents that list the mathematically optimal play for every player-hand total against every dealer up-card, under a fixed set of table rules. They do not alter the game, the cards, or the house edge; they simply remind a player of a decision that is already permitted within the rules of the game. The game itself does not forbid consulting a printed reference, but the operator running the table may.
Casinos regulate the physical environment of the table for reasons of game integrity, pace of play, and floor security. A printed chart is a physical object at the table, and physical objects at the table are subject to house policy. That is why the answer varies by property and sometimes by table or by shift.
How the policy is typically structured
There is no external regulator that sets a single rule on strategy charts for every casino. Instead, each property's table-games management decides what may be brought to the felt. The most common policy structures are:
| Policy type | What it means in practice | What to confirm |
|---|---|---|
| Permitted at the table | A printed or laminated basic strategy card may be placed on the table or held in hand while playing. | Whether the card must be kept face-up, whether it may touch the felt, and whether it may be used during every hand or only between hands. |
| Permitted but not on the table | The chart may be consulted while seated, but must remain off the playing surface, such as in a pocket or on a chair. | Whether the dealer or floor supervisor must be shown the chart before play begins. |
| Prohibited entirely | No printed chart may be brought to the table or consulted during play. | Whether a phone-based chart is treated the same as a printed one, since many venues prohibit phone use at the table regardless of content. |
A venue that permits printed charts may still prohibit electronic devices at the table, which means a phone-based chart app is often treated differently from a laminated card. The distinction is not about the chart's content but about the device category, and that distinction is also house policy.
What changes the answer from one casino to the next
Several factors explain why two casinos in the same city can give opposite answers. The first is the property's own floor procedure: some operators believe charts slow the game, while others accept that a player consulting a chart is not gaining an advantage the house does not already price into the game. The second is the table's minimum and the pit's discretion: a floor supervisor may allow a chart at a lower-limit table and disallow it at a higher-limit table, or may allow it during a slow period and ask for it to be put away when the table fills.
The third factor is the distinction between a basic strategy chart and a deviation chart. A basic strategy chart is static and widely published. A deviation chart, which adjusts play based on the composition of remaining cards, is sometimes viewed differently by floor staff, even though neither chart changes the house edge of the game itself. The fourth factor is local regulation: some jurisdictions impose their own conditions on what may be used at a gaming table, and those conditions sit on top of house policy.
Where the authoritative answer lives
The only source that binds is the casino where you intend to play. The channel that holds the current answer is the property's own table-games or guest-services desk, reached through the contact method published on the property's own website. Ask specifically whether printed basic strategy cards are permitted at the table, whether they may be placed on the felt, and whether the policy differs by table limit or by time of day.
If you are already at the property, the floor supervisor or pit boss at the table is the person who can give a binding answer for that table at that moment. A printed card shown to the dealer before you sit down is the most direct way to resolve the question without ambiguity, and it avoids the situation where a policy is enforced differently mid-session.
What to confirm before you go
- Whether printed basic strategy cards are permitted at the table, and whether they may touch the felt.
- Whether phone-based charts are treated as electronic devices and therefore prohibited at the table even if printed charts are allowed.
- Whether the policy differs by table minimum, pit area, or time of day.
- Whether the venue requires the chart to be shown to the dealer or floor supervisor before play begins.
- Whether any local regulation adds a condition beyond the house policy.
FAQ
Is it against the rules of blackjack to use a strategy chart?
No. The rules of blackjack do not forbid consulting a reference document. Basic strategy charts simply restate decisions that are already permitted within the game. What governs their use is the individual casino's table-games policy, which can permit, restrict, or prohibit printed charts at the table.
Can I use a blackjack chart on my phone instead of a printed card?
That depends on the venue's device policy, which is separate from its chart policy. Many casinos prohibit phone use at the table regardless of what is on the screen. Even where printed charts are allowed, a phone-based chart may be disallowed because the device itself is restricted. Confirm both policies with the floor supervisor before relying on a phone.
Why do some casinos allow charts and others do not?
The difference comes from each property's floor procedure and its view of game pace, not from any change in the house edge. A basic strategy chart does not give a player an advantage the house has not already priced into the game. Some operators accept the chart as harmless; others restrict it to keep the game moving or to maintain a consistent table environment.
