Another maze! This one is TRICKY. The goal is to move the ball bearing from one side to the exit. Once you drop down the rabbit hole you realize that the state of the maze changes by pushing the shuttle up and down. So not only must you figure out the internals, but you have to figure out the state the maze is in depending on shuttle location. A maddeningly difficult and interesting design...I think this may be my favorite of the update.Construction of this puzzle is super nice, with a ton of ti...

This little gem was a last minute addition to the update. A fairly low level 7.2, it's nonetheless fairly tricky. I ended up solving it outside the box because things got tricky quickly once they were inserted. The 2:1 ratio of endgrain dispite having 2x2 sticks, and having a final 5x5 solved volume is fairly unique, and I found this design to be very well executed.The construction of this puzzle is spot on, with just a little room inside for high humidity situations. The pieces are of course mi...

Ages ago I made a small batch of RD puzzles using octahedral clusters (truncated rhombic dodecahedra or chamfered cubes). I never did make the best of Coffin's design though, the Five Piece version, so I thought I'd whip up a batch after having so much fun with the Pyracubes. Five Piece Cluster has four dissimilar non-symmetrical pieces and a fifth key piece that is a single block. The serially interlocking solution is very tricky!The construction of this puzzle was done with edge beveled cubes ...

Reticulated Cubes is a fascinating exploration of 3x3 cube puzzles with a novel twist. Each box contains nine pieces, and there are eight possible cube solutions. The goal is to organize the pieces in the box such that any three pieces in a straight line will assemble into a cube (tic-tac-toe style). The solution is quite difficult to find!Note: There are two noticeable dents on the panel of the storage lid. See photo for detail. Original packaging and documentation is not included. This puzzle ...

This puzzle is more than just a pretty shape...it's also got a very interesting feature. Included with the six burr pieces is a small rectangular piece which can be added to the inside of the puzzle. Solved without the internal piece, Tulip has a level 16 solution. When the internal piece is added, the solution changes to a level 9.14...double the trouble for your money!The construction of this puzzle is excellent, with each piece milled from solid cherry stock. Fit is excellent, a little loose ...

Space is an aptly named caged burr puzzle designed by Dan Fast, this design is far out. The level 173 solution (145.1.5.4.4.2.2.2.2.2.2) is a tough challenge for even the seasoned burr solver to follow along with the solution file. Disassembly without aid is approaching the limits of human capabilities, but I am certain there are a select few out there with the ability and endurance to do so. The fourth photo is 108 moves into the solve.Wonderfully crafted by legendary maker Maurice Vigeroux, t...

Sher-Lock - A Notched Trifecta is a very exciting new design by IPP award winning designer Girish Sharma. This design is a part of his Sher-Lock series of padlock-shaped interlocking puzzles. The name alludes to the three different configurations of the key-shaped burr piece within the solved puzzle. We hope to offer more designs from the series in the future, and we are proud to offer this unique and challenging puzzle. Each assembly has not only a unique solution but a distinct arrangement of...

Stockade by Andrew Crowell is an excellent packing puzzle. The goal is to fit the pieces in the cage with all the gaps covered by the pieces to create the illusion of a cube inside. The solution involves 15 steps with multiple rotations to offer a good challenge and a unique display shape. We've added two extra pieces to make Stockade 2 as an extra challenge. Stockade 2 is a level 4.4.4.3.3 packing puzzle with the same goal, fill all the gaps in the frame to create the illusion of a cube inside....

Six Doors by Yavuz Demirhan is a variation on the classic six-piece burr shape. The added rings around the endgrain resemble a stile and rail door once the puzzle is assembled. Each ring complicates the movement of the pieces to reach a formidable but approachable level 14 solution.Yavuz had originally released this design in 2012, and since then has optimized the puzzle to increase the level from 12 to 14 moves to remove the first piece. The simple shaped pieces conceal a tricky dead end that m...

De Kas is a very challenging ten piece burr puzzle by Alfons Eyckmans. Four eight unit burr pieces interlock with two larger board pieces and four congruent smaller board burr pieces zig-zagging inbetween to make a very unique final shape. The design is in a similar style of Alfons' puzzles we have made in the past, specifically Spiral and Steps. With a level 24.2.2.2.2.2.2.2.4 disassembly alone is a tough task with a few dead ends towards the start.The puzzle was made from a very nicely sourced...
