To show 4.8 on Google
72 five-star reviews
With no other new reviews in between. Google rounds to one decimal, so a true average of 4.75 displays as 4.8. A true 4.8 takes 120.
At 8 new five-star reviews a month that is about 9 months.

The math assumes every new review is five stars and none arrive in between. Real feeds mix in fours and the odd one-star, so treat the count as a floor, not a promise.
A Google star rating is the plain average of every review's stars, shown to one decimal. To move it you add reviews, so the number you need depends on two things: how far the average has to travel and how many reviews already anchor it. Fifty reviews move fast in both directions; a thousand barely move at all.
How the math works
Your reviews add up to a total number of stars: rating times review count. Each five-star review adds five stars and one review. The calculator finds the smallest number of five-star reviews that lifts the average to the rounding threshold of your target (4.75 for a displayed 4.8) and to the target itself.
Worked example: 4.6 over 120 reviews is 552 stars. To average 4.75 you need 72 more five-star reviews (912 stars over 192 reviews). To average a true 4.8 you need 120. At eight new five-star reviews a month the displayed 4.8 is about nine months away.
| Rating to show (from 4.6 over 120 reviews) | True average needed | 5-star reviews needed |
|---|---|---|
| 4.7 | 4.65 | 18 |
| 4.8 | 4.75 | 72 |
| 4.9 | 4.85 | 200 |
What one review does to your rating
A single review matters most when the count is small. The table shows the true average after one 1-star and one 5-star review for a venue at 4.6.
| Reviews at 4.6 | After one 1-star review | After one 5-star review |
|---|---|---|
| 50 | 4.53 | 4.61 |
| 200 | 4.58 | 4.60 |
| 500 | 4.59 | 4.60 |
| 1,000 | 4.60 | 4.60 |
Why 4.8 is the line for entertainment venues
In the SpiniX benchmark database (September 2026), 84% of 963 US escape rooms show a Google rating of 4.8 or higher, so a 4.7 escape room sits in the bottom sixth of its category. Bowling alleys are the opposite: 3% of 908 reach 4.8 and the average is 4.27. Amusement centers sit between at 36%.

What does not work
- Buying reviews or asking staff and friends. Google removes them in bulk and can suspend the profile.
- Review gating. Sending only happy guests to Google and unhappy ones to a private form is prohibited.
- A prize for a review. An incentive conditional on the review breaks policy. A prize wheel at the exit that every guest can spin, followed by a review link nobody has to tap, does not. The escape room Google reviews post covers the line in detail.
- A one-off push. A burst of 40 reviews in a week followed by silence looks odd to Google and does nothing for the months after. A steady pace, asked at the same moment every session, is what moves the numbers above.
Where the steady pace comes from
SpiniX puts the review ask in front of every guest at the exit, right after the prize wheel, on the guest's own phone. The median venue sees 15% of guests tap the review link; the best see 52 to 63%. At 200 spins a month that is 30 review taps a month at the median.
