World of Tanks is a team-based massively multiplayer online action game dedicated to armoured warfare in the middle of the 20th century. The core of its gameplay consists of two teams made of 15 players, fighting on a battlefield against each other.
The vehicles that are present on the battlefields are divided into classes (light, medium and heavy tanks, self-propelled anti-tank guns and tank destroyers). The classes are split over 10 tiers.
In order to ensure that the “random battles” (the main game mode) keep the interest of our players, the following three conditions need to be respected in every battle:
Equality among the vehicles present on the battlefield within the two teams
Variety in the type of vehicles present on the battlefield
Unpredictability of the course and outcome of the battle
This task is being performed by a special module/system that is located on the server side of the game, the so-called “Match Maker”. This selects the tanks for both teams, makes sure that the teams are even and that each battle can start.
When the “Match Maker” first appeared in the Closed Beta (there was none during the Alpha stage), there were only two types of battle levels:
Sandbox with tanks from the 1st and 2nd tiers
Common battles comprising all the other tiers (3-10)
Since then our “MM” has evolved and a whole new sophisticated table composed of 12 types of battles was born (battle tiers).
The first 10 battle types roughly correspond to the tiers of the vehicles and their placement in the various Tech Trees. For example, a Tier IV heavy tank can only get into battles with other Tier IV and Tier V tanks.
Beyond that every tank has a so-called “balance weight”, which is a hidden numerical parameter that determines the combat effectiveness of each vehicle. It is directly linked to the type of the vehicle, its tier and role (we have chosen) in the battle.
