I don't have real-time access to current game availability. As of my knowledge cutoff, here's the landscape:
The franchise (rebooted 2018, 2022) focuses on physical toys, TV, and mobile gacha (Gormiti: Legends of the Universe soft-launched in SEA 2023). A browser/PC online game is unlikely unless newly announced.
If you find a playable version, verify it's official — fan servers exist but may be unstable.
