Not just your average sliding tile puzzle! Siebenstein-Spiele founder Jürgen Reiche has taken advantage of the principles behind digital clocks to create a challenging puzzle. The puzzle consists of several layers of pieces; moving a piece changes the way it looks as some 'bars' remain stationary and some move. The "4" on the right-hand side of the puzzle, for example, could also form part of a "6" when moved.
Made in laser-cut acrylic and stainless steel by Siebenstein-Spiele. Based in Munster, Germany, Siebenstein-Spiele was founded in 1992. Although the company is mainly known for board games, Siebenstein-Spiele also makes many wooden puzzles, several of which have been designed by company founder Jürgen Reiche.
