There is no official Ice Fishing app
This is worth stating plainly because the search results suggest otherwise.
Ice Fishing is a live table streamed from a studio. It runs in the browser, and the only app in the picture is the operator’s own — which contains their whole lobby, not this one game. A file advertised specifically as an Ice Fishing APK is either that operator app renamed, or an unrelated mobile game with a similar name.
The practical consequence: there is no version of this table that lives on your phone independently of an operator account.
