Live stats from Slotsjudge

Slotsjudge relies on its proprietary simulator, which runs 10,000 simulated rounds daily for each game and updates its data regularly; the latest figures for Apollo 77 reflect the most recent analysis. The game exhibits an expected RTP of 85.39%, but the declared RTP stands notably higher at 98.0%, suggesting the theoretical return aligns with player expectations. Hit frequency is moderate at 32.06%, meaning about one in three spins results in a winning combination, while the average win is approximately 2.66 times the stake. The maximum payout of 40x highlights the game’s potential for significant wins, yet its overall low volatility indicates frequent small wins rather than infrequent large payouts. From a strategic perspective, Apollo 77’s balance favors steady play with consistent, modest returns, consistent with its low volatility profile that appeals to players prioritizing stability over high risk.

Theme

7.5 
The following machine doesn’t feature bright symbols and background as you are in outer space and the only things you can see are craters, stars, and the spaceship. The music is relaxing and may even seem a bit depressing. On the 5x3 gaming field, casino customers will see all types of equipment for a space journey. You can also hear spacemen communicating with each other over the radio. So even despite pretty plain graphics, the atmosphere is truly realistic.
Theme
The sun and the letters that form the game’s name can both trigger additional rounds, which are the slot’s bonuses. The bonus symbols in Apollo 77 are designed to go in with the space theme, with the scatter symbol depicting the blazing Sun, Moon, and Earth. The final power icon is the wild one, which has the word WILD written on a grey background.

Apolo Bonus

The rocket on the right displays the slot’s name. The letters for this name are the symbols used in this slot. As soon as they take part in a winning combination, they are illuminated on that rocket.
