Today I found these three items wrapped together and since they have lived together in storage for 18 years I just can't separate them now. Besides they (at least two of them) are from S.T. Coffin.
Box Rebellion #195 IPP24 from Tokyo a very cool and small puzzle
Slot Machine #185 IPP24 also from Tokyo.. does it pay out a large cash prize... pretty sure it isn't THAT kind of slot machine.
What are the numbered cubes? No clue... are they an S.T Coffin creation? That is your mystery.. it was packed with the other two... maybe you can sluthe it out.
S.T. Coffin has made many fun and challenging puzzles and here are two pristine examples.
