Lucky21 is a strategic and exciting card game where every round is a balance between smart decisions and calculated risk. The goal is simple — get as close as possible to the target number without going over it. To gain an advantage, players can use Ability Cards, which can be played before making their move to shift the game in their favor and create unexpected twists.

During their turn, each player chooses whether to draw another Number Card to increase their total or stay and keep their current score. Before deciding, players may play any Ability Cards, opening the door for strategy, combos, and surprise plays. Once all players choose to stay, the round ends.

The player (or players) with the total closest to the target number wins the round and earns points equal to their card total. Players with lower totals receive 0 points, while players who exceed the target receive negative points equal to the difference between their total and the target number. The first player to reach 100 points wins the game.
