In Noggin, players take turns dealing their cards — a combination of letter cards and action cards — equally on three piles. When an action card appears, the other two piles will have letter cards on top, and the action card tells you how to use the two visible letters to create an answer, ideally as quickly as you can!
For example, the letters M and A combined with a “Describe” action card could be answered with “Amazing Magician”, whereas a “Name Initial” card might prompt you to say “Muhammed Ali”. If you give an answer first that your playing partners agree is credible, you keep that action card. Whoever collects the most action cards wins.
