Gift for 12 year old boy maths geek

[boygirlcatdog]

Budget under £20. Possibly a puzzle, game, calculator. I don't think he'd want a book or anything that needs making (Lego/electronics kit etc). He's more into maths and logic puzzles. Obviously into lots of other stuff like football and computer games but I think his parents will have this covered!

Thanks!

This game or any of the others from the same company (smart games) have kept my similar kids busy for hours.

That looks brilliant thanks. Exactly the sort of thing I was thinking

Maybe sudoku puzzle book, chess, dominoes or Rubik’s cube

Something Alan Turing related puzzles books.

Test for applying to work for GCHQ printed from online or print samurai sudokus and make into a personalised booklet yourself
