Player Score: our 0–100 rating from thousands of player reviews on trusted review sites and official app stores. Unhappy players post more often, so we adjust for that. Poor is under 40, mixed 40–59, good 60–74, great 75 and up. Scores marked est. are estimates for newer sites: their own reviews so far, blended with the scores of their sister sites (same company, same payments and support). How we score

What sharing a licence means

One self-exclusion closes all 5

Self-exclude at Happy Tiger and Spin King, Lux Casino, King Spin and one more close to you as well, because all five share one licence.

Separate accounts and offers

Happy Tiger and its four sisters each need a separate sign-up, so every welcome offer is open to you once per site.
