Bonanza Logic Description:

Have a good time - take part in treasure gathering together with the dwarf in mysterious dungeons! The goal of this logic game is to clear one level after another from the most of jewels on the playing field.
You have to throw one jewel at another of the same type. Thrown jewel takes off all jewels
of the same type on its way. If it collides with the one of another type, the jewel of another type returns to the dwarf, and the thrown item remains on its place.
During the flight, the jewel may bounce off the walls and ledges on the ceiling - sometimes, it can help you a lot.
