King of Thieves (KoT) is a PVP multiplayer game that combines elements of tower defense and platformer games.
In the world populated by little cunning thieves, your ultimate goal is to obtain the most valuable gems and to become the richest thief in the world.
The higher the value of your gems, the more rating you have and the higher you are on the league's leaderboard. 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 get gems is by stealing them from other players. Stealing in KoT is not considered a bad thing, but rather like a national sport.

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