The tool you mark with is a venue equipment rule, not a game constant
A keno ticket is a paper or digital grid of numbers, and a player's first action is to mark the numbers they want to keep for that draw. Whether a pen is allowed for that marking is not set by the game of keno itself. It is set by the equipment the venue chooses to issue, the surface the ticket is printed on, and the scanning system that reads the ticket after the draw.
Many keno operations issue a dedicated marking tool, often a crayon or grease pencil, because that tool leaves a mark the venue's scanner reads reliably. A standard ballpoint pen can tear thin ticket paper, smear on coated stock, or leave a line the optical reader does not register. That is why the question cannot be answered with a single yes or no: the answer lives in the venue's current equipment choice, not in the rules of keno.
This article explains what governs the marking tool, how the ticket moves through the system, and where the authoritative answer for any given venue is published. It does not state a price, an opening hour, a room rate, or a facility count, because those are changeable facts a reader must confirm with the property itself.
What the marking tool has to do
In a paper-based keno game, the marked ticket has to survive three stages. First, the player marks selections clearly enough that the venue's staff or scanner can read them. Second, the ticket is compared against the numbers drawn for that game. Third, the result is recorded against the player's wager, either by a cashier or by an automated reader.
Each stage puts a different demand on the marking tool. A pen that writes cleanly on ordinary paper may fail on thermal ticket stock, which is common in keno because tickets are often printed on demand. A pen can also press through the paper and leave indentations on the ticket behind it, which can corrupt the next ticket in a stack. A crayon or grease pencil marks by depositing pigment on the surface without pressing into the paper, which is why it is the traditional keno marking tool.
The venue's decision is therefore an equipment compatibility decision, not a preference. The tool has to work with the ticket stock, the scanner, and the handling process. When any of those changes, the allowed tool can change too.
How the ticket moves through the venue's system
Understanding the marking tool requires understanding the ticket's path. A player receives a blank keno ticket, marks the chosen numbers, and submits the ticket with the wager. The venue records the selections, runs the draw, and then determines whether the marked numbers match the drawn numbers closely enough to pay.
The moment of recording is where the marking tool matters most. If the venue uses a human cashier to read the ticket, the tool only needs to leave a mark a person can see. If the venue uses an optical scanner, the tool needs to leave a mark the scanner's sensor can distinguish from the printed grid. A pen that looks perfectly legible to a human can be invisible to a scanner that reads only a specific pigment or contrast level.
That is why the question "can you use a pen" is really a question about the venue's scanning and recording method. The same venue might allow a pen at a staffed counter and disallow it at a self-service kiosk, because the two channels use different readers.
| Stage | What happens | What the marking tool must do |
|---|---|---|
| Marking | Player selects numbers on the ticket | Leave a visible, non-tearing mark on the ticket stock |
| Submission | Ticket and wager are handed to the venue | Survive handling without smearing or transferring |
| Recording | Selections are entered into the game system | Be readable by the venue's chosen method, human or scanner |
| Draw comparison | Marked numbers are compared with drawn numbers | Leave no ambiguity about which numbers were selected |
The table shows why no single answer covers every venue. A tool that passes the marking stage may fail the recording stage, and the recording stage is the one the venue controls most tightly.
Digital keno removes the marking tool question entirely
Many venues now run keno on electronic terminals or video keno systems. On those systems, the player selects numbers by touching a screen or pressing buttons, and no physical marking tool exists. The question "can you use a pen" does not arise, because there is no paper ticket to mark.
That does not mean the question is obsolete. Paper keno remains common in many venues, particularly where keno is run as a lounge game with a live draw shown on screens. The distinction matters: a player asking about a pen is almost certainly describing a paper-ticket game, and the answer depends on whether that venue still runs paper keno at all.
If a venue has moved entirely to digital keno, the marking tool question is answered by the equipment itself: no ticket, no tool, no pen. If the venue runs both paper and digital keno, the rule may differ by channel, and the player must confirm which channel they are asking about.
Where the authoritative current rule is published
The marking tool rule is not a secret, but it is also not stable enough for this article to state it as fact. The authoritative source is the venue's own published game rules or its keno desk. A player should check the venue's website, look for the keno section, and read the equipment or ticket-marking rules. If the website does not state the rule, the keno desk or guest services line is the correct channel.
Before travelling, a player should confirm three things: whether the venue runs paper keno or only digital keno, which marking tools the venue issues or permits, and whether the rule differs between the staffed counter and any self-service kiosk. Those three answers settle the pen question for that venue on that day.
What to confirm before you go
The items below are the changeable facts this article deliberately does not state, because they vary by venue and by time. Each item names the channel that holds the current answer.
- Whether the venue runs paper keno, digital keno, or both — check the venue's keno page or call the keno desk.
- Which marking tools are issued or permitted for paper tickets — check the venue's game rules page or ask at the keno counter.
- Whether the rule differs between a staffed counter and a self-service kiosk — confirm with the venue's keno staff.
- Whether the venue's scanner reads pen ink or only the issued crayon or pencil — ask the keno desk directly.
- Any fee or minimum wager attached to paper keno versus digital keno — check the venue's current keno pricing page.
Confirming these items takes a few minutes and prevents the frustration of arriving with a pen the venue will not accept, or discovering the venue no longer runs paper keno at all.
FAQ
Is a pen ever allowed for marking a keno ticket?
It depends on the venue's ticket stock and scanner. Some venues issue crayons or grease pencils because those marks read reliably on thermal paper. A pen may be allowed at a staffed counter where a human reads the ticket, but disallowed at a scanner-based kiosk. The venue's keno desk is the only authoritative source for its current rule.
Why do keno venues issue crayons instead of pens?
Keno tickets are often printed on thermal or coated stock. A crayon deposits pigment on the surface without pressing into the paper, so it does not tear the ticket or indent the tickets beneath it. A ballpoint pen can tear thin stock, smear on coated paper, or leave a line an optical scanner does not register.
Does digital keno require a marking tool at all?
No. On a digital or video keno terminal, the player selects numbers by touching a screen or pressing buttons. No paper ticket exists, so no pen, crayon, or pencil is involved. The marking tool question only applies to paper-ticket keno, and the venue's keno page will state which format it currently runs.
