# The Shell Game: Program for TS1000/1500

Type-in BASIC program implementing the three-cup Shell Game for TS1000/1500. Player starts with $100, bets any amount, watches cups shuffle, guesses which cup hides the pea (1-3), plays until broke, then receives a tally of total attempts, correct guesses, and accuracy percentage.
