Slot Machine - Stewart Coffin Design #185 by Henry Strout

This classic Coffin design was Henry’s IPP 24 Exchange puzzle at Tokyo, Japan  in 2004 and marked his second appearance in the exchange.

Eric Fuller (RIP) released (2005) a modified version with a wood slotted top to make the puzzle much more difficult!

Here’s Stewart’s description:

“Try your luck on this one - or test your patience! The seven polyomino-type pieces of Slot Machine are inserted through the 1x2 slot in the clear plastic cover of the 3x3x3 box, but not without some difficulty.”
