RTP (Return to Player) is the theoretical percentage of wagers a slot returns to players over time. For example, a 96% RTP slot returns $96 for every $100 wagered on average. Higher RTP = better long-term value.
RTP is calculated over millions of spins. Individual sessions can vary wildly regardless of RTP.
RTP = Long-term return percentage
Volatility = Risk/reward pattern
A 94% RTP high-volatility slot can be more entertaining than a 96% RTP low-volatility slot depending on your play style.
Check game info screens for RTP and volatility. High RTP doesn't guarantee wins, but offers better long-term value. Choose volatility that matches your budget and play style.
Decide how much you can afford to lose before playing. Use deposit limits. When your budget is gone, stop. Slots are entertainment, not income.
Most Ontario casinos offer demo/free play modes. Test games risk-free to understand features and volatility before wagering real money.
Playing max bet doesn't improve RTP on most modern slots (check game rules). Bet within your budget for longer play sessions.
Slots are designed to be entertaining, but the house always has an edge. No strategy or system can overcome RTP. Only gamble with money you can afford to lose.
