Description
Cast Oskar, first released in 1987 and highly popular among puzzle collectors, has now been revived as “Cast Key III” with new gimmicks added. At first glance, it appears to be a flat puzzle where three keys are to be pulled out from the case… Designed by Oskar van Deventer from the Netherlands.
