Bonk is a card game where up to 5 players strive to create different combinations, over a series of seven rounds. The overall goal is to accumulate the lowest score by strategically collect and play certain sets of three-of-a-kinds and straights, utilizing wild two’s and taking advantage of the unique "Bonk!" feature. Every round brings a new challenge to try to complete with your hand. The first is the easiest one, and then the game gets more and more challenging with every round. You get one additional card in your hand for every round, starting with 7 and ending with 13. The final round is the most challenging one and also includes some special rules to make it even more exciting.

In the game, players take turns drawing a card from a draw pile and a discard pile, hoping to get the cards needed to complete the round. The player can organize their cards according to the required hand for the round, to make it easier to see which cards are lacking. When the player have the complete set, they may reveal their cards, by placing them onto the table. First player to get rid of all cards on their hands, wins that round.

When the final, 7th round is over, the game is over. Every player counts their points, and the one with the lowest points is the winner of the whole game. As the final round holds a lot of points for everyone except the winner of that round, a lot can change.
