Select matching pairs of tiles to clear them from the screen.

Click on a tile to select its visible face. Click and drag sideways to flip a tile and select its hidden face.

If you cannot find a match, discard a tile by clicking it and dragging up or down. A new tile will be dealt in its place.

Some tiles have concealed faces, showing a ? instead. These tiles cannot be discarded.

Tile faces with an * match any face (of like color).

Gold tiles match every tile showing the same face value (including concealed faces). Gold tiles cannot be discarded.

Black-on-white tile faces do not match white-on-black tile faces.

Clicking and dragging sideways without touching a tile will flip all unselected tiles. You can do this at any time during a Clocked game, but only once per matched tile pair in a Patience game.

Clearing the screen advances the game to the next deal. In a Clocked game, new tiles are also dealt whenever the timer expires before you clear previous deals. In a Patience game, new tiles are also dealt whenever you have selected three non-matching pairs or consecutive discards before clearing previous deals.

If all tiles in a deal cannot be placed in the clickable playing area, they will be placed in the overflow stack at the bottom of the screen. Overflow tiles are redealt after a match clears space for them. When a deal cannot be completed because the overflow stack is full, the game is over.

You receive points for each non-* tile matched, double points for matching a ? tile with a non-* tile, and bonus points for clearing with time to spare. Every third screen clear increases points awarded. In a clocked game, you lose points when you discard tiles. In a Patience game, you do not receive points for tiles matched after the timer expires.

Clocked game deals are unlimited. A complete Patience game is twenty-four deals. Can you clear them all?
