Time Is Money Game allows you to pay for speedy/instant access to things that can also be gotten through gameplay

World of Tanks is a free-to-play PvP experience about fighting other players in tanks.

World of Tanks features an optional "Premium" subscription that greatly increases the rate at which you level up and earn Credits, the game's in-game currency. There's also a premium currency, "Gold". Credits, Gold, Premium subscriptions, in-game tanks, and garage slots to store your in-game tanks can all be bought with real money, individually and in a large variety of combinations and package deals too numerous to list here (see the External Links below for a link to the game's real-money shop).

The game's real-money store states that it is technically possible to research any vehicle set without spending money, but also makes it clear that buying Gold "can ease your progress along the Tech Tree" and will help the player "reach the desired target much faster".

Both Credits and Gold can be used to purchase a large variety of things in-game, many of which directly influences your tanks' power. Infamously, this includes "premium ammo", ammunition for your tanks (which is, of course, consumed with every shot) that's more powerful than what you would otherwise have access to. Premium ammo and equipment are now technically buyable with non-premium credits, but at an inflated price comparatively, making buying with real cash more appealing.

The game often features time-limited events where "crates" (loot boxes) can also be purchased for Credits and Gold.
