Currently, there is no official confirmation from Supercell about bringing back the half-price upgrade event, popularly referred to as “Slash Royale,” in 2025. The last instance of this event was in October 2021, and there are no updates or confirmations of its return in the current year. Since coin resources are scarce and no such activity is planned, it’s best to plan your upgrades carefully and follow official Clash Royale media for any future updates.
