Ubongo Extrem Craxy Expansion
This brand new expansion to the already-overly-challenging Ubongo Extrem takes gameplay up one notch higher than it really should ever go. With 70 all-new puzzle cards, each with 4 solutions, featuring five (5!) pieces on each card, Ubongo-ists will find themselves doing mental gymnastics of Olympic-level caliber.

Then again, how hard can these new puzzles really be? After all, many of them were designed by Gage Alspach (age 10) and Dakota Alspach (8), who were growing bored with the relatively limited challenge of the 4-piece puzzles available out of the box.
