Numlock is an n-ary puzzle designed by Pit Khiam Goh and crafted by Johan Heyns with help from Jack Krijnen.  Theoretically, the puzzle could be increased to any odd-number-ary size (Johan has made a 7-ary/9-ary version) this ternary/quinary option was quite enough for me!  The toughest setting will need 404,999 moves to release the first piece but I will ship it in the more modest 47-move setting.  Please read Kevin Sadler's excellent review at https://www.puzzlemad.co.uk/2017/11/not-jingly...

Sequential Star looks like the well known Diagonal Star but the pieces have pins and mazes in the central block of each piece, which complicates (dis)assembly.  This necessitates a twelve move sequence which, when mastered, is not difficult to remember.  Lee Krasnow is renowned for his accuracy in puzzle making and this is no exception.  The six puzzle pieces are of similar shape but have different mazes and each piece is made up of three blocks which are not glued but held together by neodym...
