King of Thieves (KoT) is a multiplayer PVP game that combines elements of tower defenсe and platformer games.
In the world populated by cunning  little thieves, your ultimate goal is to acquire the most valuable gems and to become the richest thief in the world.
The higher the value of your gems, the higher your rating and the higher your ranking in the league. Keep winning leagues to reach the Top 1 in the final King's League and to become the King of Thieves.

The most efficient way to obtain gems is to steal them from other players. Stealing is not considered a bad thing  in KoT, but rather a national sport.

Beware, though - other players can steal your gems too. This is why it is so important to defend them by setting traps in your dungeon.
