The Pokémon Company has confirmed that the payment currency for Pokémon Sleep will change from the Bulgarian lev to the euro starting Jan. 1, 2026, following Bulgaria’s adoption of the euro as its legal tender. The update affects in-app purchases for players in Bulgaria and aligns the game’s pricing with the country’s new currency system. No gameplay changes are tied to the switch, and existing content will remain the same. The change is largely administrative, but it ensures Pokémon Sleep stays consistent with local regulations as the transition to the euro officially takes effect.
