Tanki Online (TO) (Russian: Танки Онлайн) is a browser-based multiplayer free-to-play video game created and published by AlternativaPlatform [ru].

The developers began working on a full-scale MMO action game based on this demo in 2009, which became Tanki Online.

[4]Tanki Online used the company's own game engine, Alternativa3D, which ran on the Adobe Flash platform.

Instead of choosing a tank from a pre-made list, players are encouraged to assemble their own battle machine, combining turrets, hulls, protective modules, drones, and decorative paints, according to their preferences.

The fifth drop box is the “Nuclear Energy”, which when picked up recharges the Overdrive – a unique hull ability.

Crystals are earned by playing in battles, completing challenges (Battle Pass), opening weekly and regular containers, opening coinboxes, taking Gold Boxes (drop boxes that contain 1000 crystals), exchanging Tankoins, using promocodes, and participating in contests from the game helpers and developers.

Players can buy regular containers, coinboxes, crystals, sets, skins, paints, the ability to change their nickname, a clan license, and Gold Boxes for Tankoins.
