In Figures the playing field is reset to a new figure each level and later on tiles and lines suddenly appear.

There is also a Demo mode in which you can watch your CPU playing while enjoying a cup of tea!

In Widelands, you are the regent of a small clan. You start out with nothing but your headquarters, where all your resources are stored.

In the course of the game, you will build an ever growing settlement. Every member of your clan will do his or her part to produce more resources---wood, food, iron, gold and more---to further this growth. The economic network is complex and different in the five tribes (Barbarians, Empire, Atlanteans, Frisians and Amazons).

As you are not alone in the world, you will meet other clans sooner or later. Some of them may be friendly and you may eventually trade with them. However, if you want to rule the world, you will have to train soldiers and fight.

Widelands offers single-player mode with different campaigns; the campaigns all tell stories of tribes and their struggle in the Widelands universe! However, settling really starts when you unite with friends over the Internet or LAN to build up new empires together---or to crush each other in the dusts of war.
