More suited to people younger than I. My mother bought one of these for my 12th or 13th birthday and I loved it and wanted it back.
Great for the youthful puzzler, basic solution once you know how to do it - I remembered how to do it after not touching one for 20 odd years.
I had this when it first came out back in the day and it brought back so many memories, it's still enjoyable to have a go at, love this puzzle and amazed to find an original one in mint condition.
