Siebenstein - Spiele 2012.
(Wood and plastic, 3.4" x 6" x 1/2" body
with 8.5" long sliders made from 1/4" thick wood.)
The discs can be moved by tilting the puzzle,
and one can prevent a disc from moving with a finger in the horizontal opening in the plastic.
The task is to mix up and then arrange the discs so that the colors line up in pairs,
with the pieces with the stars in the center on the bottom row.
The discs are made with woods of different colors,
but are hard to tell apart;
this puzzle has color added along the rim of each disc to match the directions.
