The deck contains 56 cards.
In each deck, there are 56 cards: 0 to 20 in blue and orange and 0 to 12 in lilac together with an instruction card.
Numbers are represented by the dots on the dice using the finger counting system: for example, 6 is represented as 5 and a 1; 14 is 5, 5, 4; 19 is 5, 5, 5, 4.
Only schools and colleges can order the decks only.
