Butterfly Effect: A solitaire weather deduction game for rainy days.

You love to look at the clouds. You always have. They call you a dreamer. Don't listen! One day they'll know what you are: A true expert in your field!

The weather is represented by a small deck of cards. Each card shows a weather (sunny, cloudy, rainy or windy). On turn, you assign one of your forecast tokens to any of the four weather types and flip the top card of the deck. If you're wrong, you lose the token. To win the game you have to forecast the weather correctly seven times in a row.

• Are you joking? That's random! You're just guessing! You'd better not tell a meteorologist!

But of course there is more to it...
