You may see RTP, jackpot eligibility rules and max win information, but not the exact chance of hitting the top prize. Volatility describes how uneven the session may feel to players, on average. An important rule to take into consideration is minimum stake rules, as some games require a minimum qualifying bet to be eligible for a jackpot.

This fund increases continuously as the game is played and is paid out when the jackpot trigger is activated, awarding the full accumulated amount to a single spin. That pool increases over time and is paid out only when a specific jackpot condition is met, after which it resets and starts building again. Bet levels, qualification rules, and session limits define what is possible long before any spin result appears.
