The goal of SUPER 21 (BLACKJACK) is to drop the colored orbs into columns to create sums of 21. Go over 21 or 'bust' and the column takes damage. Damage a column 3 times and you lose it. The game ends when 5 levels are cleared, or all your columns break. We are playing Blackjack with marbles. You don't need playing card to play my form of Black jack 21. Super 21!
