Reach the floor target without busting.

Rules: Shuffle a single deck into a 4×4 grid. You start on a random tile — swipe ↑ ↓ ← → to move there and absorb that card. After each swipe the rest of that row/column slides and the far edge refills from the deck (peek the next card at right).

Floor minimum is always ≥16 unless modifiers say otherwise. Only Play Card spends a turn — you get 12 plays per floor to hit 250 points plus +30 per floor and +60 on boss floors. Hand value still pays +10 per point over the floor (or +100 at 21) and multiplies by cards-in-hand beyond two.

Input: Use the arrow keys to swipe. Cash the hand with Space once eligible. Undo with U. Start fresh with R.
