This was very tricky indeed with su...

My interpretation stayed true to Jakub's original design with a couple of changes - we fully lacquered and changed grain direction for all pieces to make the solution more difficult. The result is trickier than I e...

The Bamboozler from Serhiy Grabarchuk (Bits and Pieces)Twelve small bunches of bamboo pieces need to be put together in the stand to make a bundle of bamboo pipes.  This puzzle was surprisingly difficult.  It’s probably (unintentionally) a dexterity puzzle too… it was not easy to keep the pieces stable in the stand.  I’ve enjoyed a couple other puzzles from Grabarchuk but this one was tough.  The photos are careful to avoid any possible spoilers.The wood puzzle is in great conditi...
