This must be done in such a way so that it is easy to count the open cards in each category. There are some special rules for the first round of each heat. Furthermore, no cards are revealed in the first round. A heat continues until all players have exactly three cards remaining in their hands. No further bets are placed.
All players choose one of their cards to discard, face down.
These cards do not count in this heat. Now, the remaining cards in each player's hand are simply added to the open card layout. To ensure clarity, open cards are laid out by category. At the end of each heat, scoring takes place. By category, the open cards are totalled to determine the results of the bets.
