About
One card at a time, four columns, and a single goal: bring a column to exactly 21 and it clears. Go over and it costs you a DROP. Number cards count their value, face cards ten, the ace one or eleven – and a joker finishes any column on the spot.
HOLD parks a card you cannot use yet, DROP throws away one that fits nowhere. You start with twelve DROPs; once they are gone, the next discard ends the game. Every 21 raises the multiplier and lights that column's star, all four stars together earn a bonus, and three sevens pay extra.
There is no timer and no dealer: every move takes as long as you like. A guided practice round walks you through your first game, and three card styles with several table and card colors let you set the table your way. It is the kind of game that fills a five-minute wait and then quietly eats twenty.
