Snapjack

Bet it all in SNAPJACK - the memory-based card game that tests your speed, concentration, and Blackjack skills all at once!

The rules are simple. Our house manager, Blue, will deal your hand face-up in front of you. Pick the cards that add up to 21. Go over, and you'll bust. Pay close attention to your cards, though - because in a few seconds, they'll be hidden from you! 

Make as much money as you can before your time is up! Good luck!

@Awesome3475 and I made this game in 48 hours for the CreativeWorks Weekly Jam #2. No real money is being gambled here, don't worry.
