ALTEKRUSE PUZZLES

Similar to Burr puzzles but with uniform pieces. This puzzle was patented in
1890 by W. Altekruse. Solutions are primarily dependent on determining the necessary
sequence of assembly, although proper orientation of each piece is also required.
The puzzle will stay together until one group of pieces is slid. The overall
difficulty is generally proportional to the number of pieces.
