Regulatory
Skill Game
Definition
A game whose outcome is determined predominantly by player skill rather than chance, which in many jurisdictions places it outside the definition of gambling.
Why it matters
The skill and chance distinction is one of the oldest fault lines in gambling law and one of the least consistently drawn. Some jurisdictions apply a dominant factor test, asking which element predominates; others ask whether any material chance element exists at all. The same product can therefore be a licensed casino game in one market, an unregulated skill game in a second and a criminal offence in a third.
The stakes are large where the classification carries a whole industry. Fantasy sports, rummy, poker and certain arcade-style terminals have all been argued as skill games, and national courts have reached opposing conclusions on essentially identical facts. Legislatures have periodically settled the question by statute, sometimes abolishing the distinction entirely for online real-money play.
For operators the practical risk is that a skill classification is rarely permanent. It survives at the pleasure of a legislature that can redefine it.
The bottom line
Skill is a legal category rather than a mathematical one. Building a business on it means building on a definition that a parliament can change in an afternoon.
