Live stats from Slotsjudge

Slotsjudge utilizes its own simulation software, which plays 10,000 rounds per game daily and updates data regularly, with the latest figures reflecting the most recent analysis. For Apollo 77, the simulated RTP stands at 90.88%, while the declared RTP is notably higher at 98.0%, suggesting a favorable payout structure for players. The hit frequency remains relatively low at 28.16%, but the average win of 3.23x and a maximum win of 40x indicate potential for sizable payouts within a low-volatility environment. These metrics point to a slot that offers steady, smaller wins with occasional larger payouts, which suits players seeking consistent, low-risk gameplay. Overall, the game's performance, as examined through Slotsjudge’s simulation, demonstrates a balanced balance between frequent modest returns and the chance for bigger rewards.

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.

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.
