The heat map shows an effective sunshine amount per person. The red areas have plenty of sun, while purple areas have little sunshine per person.

In the future, the extra sun will increase their wealth or perhaps sustain much larger populations.

Game of mine sweeper with mathematical and logical elements set in a  theme and modes that resemble MineCraft for your Android Device!

Do you like MineCraft? So do we! This is a game for those who can’t wait to play MineCraft again. It features 2D mine where you aim to gather as many resources as possible. But on your way you stumble upon zombies and creepers. Will you succeed to mine and stay alive?

This game is based on rules of mine sweeper. But it has custom game mode that has lives and food hidden somewhere in the map. The game also has virtually unlimited map size – uncommon among minesweeper games. We hope you like it!
