Lucky Seven ... fast and fun competitive solitaire played with 7 coasters.
Solitaire is (usually) played by one but this game may be played by any number and is therefore oxymoronic!
The object is to turn all 7 coasters number side up.
Shuffle 'em and deal 'em number side down … then, turn over any coaster and leave it in place … from here on it is all pure luck as the number on the coaster turned, determines the position (always reading from left to right) of the next coaster to turn … and so on.
However, if the number on a coaster turned denotes the position of one already turned, that player is bust!
Shuffle 'em and pass 'em to the next player … or start again if playing solo.
