Maumee River Solitaire is based on the card game Herringbone. It is named after the Maumee River in Ohio.
Goal: Build up the eight wrap-around foundations by suit. You can play a card to the foundation by clicking on it or dragging it to the appropriate spot.
Played with two 52-card decks.
The foundations can all be built upward or downward; a blue arrow appears once you've played a card on a foundation other than the initial rank, showing the direction to build.
The top of the discard pile can be played to the foundation or to an empty free space.
Clicking on the deck will add a new card to the discard. The deck can be flipped over as often as needed; the number on the card back tells you the number of times you have gone through the deck.
A card in a free or dock space can be played to the foundation.
When a dock space is empty, it is filled by the last card in the river. Once the river is empty, dock spaces act as free spaces.
The button makes all safe* moves to the foundation; other cards that could be moved to the foundation are highlighted, as is the button. Double-clicking on the button makes this run automatically every time a card is drawn.
*A card is safe to move if its duplicate isn't in the river or on the docks.
The and buttons provide unlimited undo and redo.
The button switches between a left-handed and right-handed layout.
