use arrows to move the cursor
use ON to select cards, move cards, reveal hidden cards, ...
use PLAY to move a card from the remains' stack to the top of the cursor
use F1 to put card under cursor on one of the 4 final stacks
use F2 to un-select card if a card was selected, else draw 3 new cards
out of the remains' stack
use F3 to put card on top of the remains' stack on one of the 4 final stacks
