The tablet or smartphone device can inform you when this has happened, triggering a retaliation mechanic to go and steal them back. While multi-player options are common, the ability to take it in turns to attack opponent strong holds makes this unique. It's the asynchronous game-play and persistent worlds that are most unusual here. The more gems you steal, the higher your scores in ratings and leagues.

Gems are the main treasure and are crucial for game progression. Players have to run, jump and dodge traps, while all the time competing to break into each others customizable dungeons all the time trying to accumulate gems and gold. This creates a compelling back and forth as players work to make their home level hard to traverse, this protecting their stores. The game is of particular interest to families because it offers a new, hybrid, multi-player mechanic where players can steal each others loot. ZeptoLab is releasing their new multi-player game King of Thieves today on iOS today (coming to Amazon February 26 and Google Play on March 5).
