This is a clever logic game with a robot at the nuclear station. The iron worker has to sort out briquettes of uranium and other materials. The task is dangerous but very interesting! The game objective is to change the briquettes in two columns in order to make groups of the same type. As soon as group has three and more briquettes there is a chain reaction and they disappear. The more briquettes disappear during the reaction, the more energy will be received by the station. And the more points you gain, uranium worker! You can load your results to the server and there you can compare them with the results of the players all over the world.
