Casino Terms Glossary
Shill — is a paid participant or covert promoter who poses as a regular player to make a casino game, table, or slot seem popular and trustworthy. Historically, a house shill is bankrolled to start action; online, it can be undisclosed hype in chats or streams that nudges players to join or bet bigger.

Understanding Shill
In gambling, Shill meaning covers any person seeded by a casino, card room, or marketer to stimulate play or shape perception. The Shill definition often contrasts with a “prop player”: a shill uses house money; a prop uses their own but is paid to keep games running. Why it matters: shilling can distort what is truly busy or beatable, affecting your bankroll choices, bonus play, and trust. At 101RTP you’ll find unbiased reviews and tools like our Slot Simulator and Bonus Value Score to test strategies and spot realistic expectations before you sit down to play.
Examples of Shill
Here are common examples of Shill behavior at casinos and online:
- House-backed table seeder. A casino-funded participant sits in on a blackjack or roulette table to start play and attract passersby.
- Stream or chat hype. An account repeatedly praises a slot’s “hot streak” or a bonus, encouraging viewers to raise bets or sign up.
- Undisclosed affiliate push. A reviewer promotes a casino or game without declaring a commission relationship, giving a false sense of impartiality.
- Event crowding. Extras are placed near a new slot bank or tournament area to create a buzz and draw real players in.
FAQs
What is a Shill in a casino?
A Shill definition in casino terms is a person who pretends to be a regular player but is actually paid or backed to make a game look active or attractive. Shills seed tables, hype slots, or promote bonuses without honest disclosure, influencing other players’ perceptions and decisions.
How can I spot a Shill while gambling?
Look for patterns: someone pushing specific tables, slots, or bonuses without clear reasons; unusually enthusiastic praise; or players who appear to risk chips without normal hesitation. In regulated rooms, disclosed roles (like proposition players) may be labeled. If a promoter can’t disclose ties or avoids questions, be cautious.
Can casinos legally use Shills?
Legality varies by jurisdiction. Some places ban undisclosed Shills but allow clearly identified proposition players who use their own money. Others require signage or uniforms if the house funds participation. Check local regulations and casino policies—undisclosed shilling used to manipulate players is often prohibited under consumer protection rules.
Is a Shill the same as a prop player?
No. A Shill typically uses house bankroll or backing and may not disclose the relationship. A proposition player (prop) is paid to help start or maintain games but uses their own money and is usually disclosed to meet regulatory requirements. The distinction affects both legality and player trust.
Do online casinos or streamers use Shills?
Some do. Undisclosed promotional accounts or scripted hype can make a slot or bonus look better than it is. Look for clear disclosures, realistic results, and independent verification. Reviews on 101RTP call out red flags and explain whether a streamer or affiliate has a declared commercial relationship.
Why does Shill activity matter to a player’s bankroll?
Shills create artificial urgency and popularity signals that can lead you to overbet, play unsuitable games, or chase bonuses that don’t fit your risk profile. Recognizing the tactic helps you slow down, check RTP, variance, and wagering rules, and keep your gambling aligned with budget and goals.
How do I make smart choices if Shill marketing is around?
Verify claims, compare RTP and volatility, and test stakes before committing. Use independent sources: on 101RTP, we provide honest casino and slot reviews plus tools to model outcomes, so you can judge whether a game or bonus is genuinely good for your bankroll—not just good for the hype.
