objective: defeat all 14 enemies in the tower.

draw cards to build a strike total.
send it when you meet or exceed the enemy target — without going over 21.
jacks need 12, queens need 15, kings need 18.
stop short to guard (take less damage), bust at 22+ for full damage.
hit exactly 21 to heal.
jokers are hazards — flip: even = safe, odd = danger.

you start with 20 hp. don't die.
