Welcome to Twenty-One Run! The goal is to collect game pieces totaling 21 without going over. You need at least 3 pieces to complete a set and there is a bonus for matching colors. Move left and right to dodge and collect the pieces to make your set. Press space or click 'Send' to receive points for the current hand. If you go over 21 in your hand it's a bust! 3 busts and it's game over!
