BrainBox® is a fast and fun memory game that does not require pens, pencils, paper, playing board or even a table! Each round takes 10 seconds and a game lasts as long as you want it to (10 minutes is the norm). BrainBox® is perfect for families and groups of friends to play - packed in a sturdy, magnetic cube box, it’s ready to play instantly wherever you are. Play solo or with as many people as you want. Each player picks a card and studies it for 10 seconds before answering a question from the back, chosen by the roll of a die. Keep the card for a correct answer - the player who ends up with the most cards wins! The 55 cards cover all the maths concepts taught in Y3 and 4 from bar charts and Venn diagrams to fractions and percentages.
