Well known1. Set the budget before choosing a world
Both modes are volatile, and Hades is described as the more extreme one. Fix the amount you can afford to lose first, convert it into a count of spins at your stake, and let the end of that count close the session whichever mode you chose.
Well known2. Use the demo to feel both modes
Reading that Olympus triggers bonuses more often and Hades pays more per bonus is one thing; watching it is another. Run a few dozen demo spins in each world and note how long the quiet stretches feel before real money is involved.
Lesser known3. Frequency against size is a trade, not an upgrade
Switching to Hades does not add value, Pragmatic Play describes it as fewer bonus rounds with a higher average win when they arrive. If long gaps without a feature would make you raise your stake, Olympus may suit your temperament better.
Lesser known4. A guaranteed wild is not a guaranteed profit
The Hades free spins always contain an expanding wild, yet its multiplier value is random and may be modest. Treat the guarantee as a feature detail, never as a reason to size a bet up.
Lesser known5. Switching mid-session needs a rule
Because you can change world at any moment, it is tempting to jump after a cold run. Write down in advance when, if ever, you will switch, and keep the stake unchanged when you do. The printed 96.07% applies to the game, not to a hunch about which world is due.
