Cha-cha is the trademark of a Belgian chocolate wafer. You could collect three different card boxes (black, yellow, red : the colours of the Belgian flag). Included were 55 cards with questions in two languages (Dutch and French, languages spoken in Belgium). All trivia questions concerning Belgium. + Who was the fourth king of Belgium? + Which chocolate based candy contains different ingredients? + Who was the first Belgian to walk on the moon? + Which famous statue has more than 600 different costumes? If you collected the bar codes of the candy, you could get a board, dices and jettons (counters) to complete the game.
