The Maths Snake puzzle is a fun puzzle suitable for anyone over the age of 8.
You are aiming to rotate the blocks until you make the equation on all four sides true. Please note the equation reads from left to right regardless of operation priority.
This is the 7 block version with each piece laser etched and fitted on a string so they rotate individually.
It looks very approachable but there are actually 1,024 permutations with only one possible solution!
Please note there are multiple variations to the sequence of numbers meaning you may not receive the same version if you order more than one.
