Bi-Nary is a challenging puzzle by Constantin. In order to solve the puzzle you need to remove the looking piece from the end.
There are four rods each with a unique maze on it and you must move these by sliding up and down to solve all four simultaneously. This is very challenging and we’d recommend for experienced puzzlers.
Bi-Nary measures roughly 24 x 16 x 2.2cm and is made from an attractive mix of contrasting woods.
