How to play
- Cards are dealt to you one at a time from a shuffled deck — the exact same deck, in the same order, as your opponent's.
- Place each card into one of your lanes. Each lane sums toward 21.
- Land a lane exactly on 21 to bank it and clear it. Push a lane past 21 and it busts — busts are limited, so place with care.
- Play through the deck; clearing it all earns a bonus. The higher total score takes the match.
Because the deal is identical for both sides, 21 Rush removes the card luck from blackjack-style play: the
only difference between you and your opponent is where you put each card. Matches are asynchronous — play
your side now, your opponent plays the same deck on their own time, and the result settles when both are in.
