|Raymond Merril Smullyan (Ray) born in Far Rockaway, New York, in 1919.
American mathematician, concert pianist, logician, philosopher and magician. Author of many books on recreational logic and mathematics. Many of his logic problems are extensions of classic puzzles.
|Based on the passage from the coffers of Porcia, that Raymond rescues from the Shakespeare's play "The Merchant of Venice", we use a variant in which four chests hide the treasure.
Thank you Ray for showing us that mathematics and logic can be fun.
