Collect the most cards by the time the Splurt! deck has run out.
Start by pulling out an arbitrary quantity of cards (based on how long you want to demo/play the game). Make sure all cards face the same direction. Shuffle the deck and place it on the table, pink side up.
Flip over the top pink card, revealing its black side. All players simultaneously race to shout out an answer that meets the criteria.
First player to call out a correct answer collects the card.
The game ends when only one Splurt! card remains. Whoever collected the most black cards wins the game!
