Overview and solo game

About Château Gardens, from BoardGameGeek:

Château Gardens is a polyomino-drawing game where players compete to draw the optimal arrangement of plants and viewing platforms around a French Château. Players draw cards from a standard deck of playing card to learn what size, shape, and/or location of polyomino they must draw in their garden, or what noble's viewing platform they must add to combo off their existing elements. Make sure you always have room to add the next element revealed from the deck, or use your suppléant card to replace it for all players once per game. You may bow out at any time you think your garden is full, or press your luck just a bit more to see if you can eke out the most points! Once all players have elected to stop adding to their garden, add up your points and determine the winner. -description from designer
