Abacus with Rubik's Cube
Mental maths from the first bead to four-digit sums in the head, over ten levels for ages 6 to 14. Children practise every day on the app and take a level exam with a certificate at every step. Rubik's Cube adds four levels (3x3, 2x2, Pyraminx and Mirror cube) for patience, memory and pattern.
