Tanki Online's official Rubies announcement states that after the October 2024 currency update, "Now there will be 3 currencies in the game:" and then lists Crystals, Rubies, and Tankoins.

That directly contradicts the article's statement that there are four currencies. Since the official post enumerates the current currencies and gives a total count of 3, the sentence naming Stars as a fourth currency is inaccurate.

Tanki Online's own announcement from December 1, 2020 says: "Starting from December 2nd, the Flash version of the game won't be working anymore." That is the explicit discontinuation date for the Flash version.

The later August 20, 2021 post does not announce the shutdown date. Instead, it says the Steam client had already been updated to HTML5 and that at that point "the Flash version is no longer supported." In other words, August 2021 marks the end of the transition stage for the Steam client, not the date the Flash version was discontinued.

So the article's date is wrong: the Flash version stopped working on December 2, 2020, not August 20, 2021.

Tanki Online's official October 24, 2024 Rubies announcement says that with the currency update, Megagolds were replaced: "after the release of Rubies, we will replace Megagolds with a new Ruby Gold, meaning Rubies will drop from all (formerly) Megagolds."

That means the article's current-tense description of Megagolds as drop boxes that contain 10,000 crystals is no longer correct. According to the official update, the old Megagold drops now award Rubies, not crystals.
