A Game with Coins

This Java applet provides practice in adding denominations of US coins in the context of a simple turn-taking game of strategy. The game starts with pennies, nickels, dimes, and quarters arrayed in a row or loop. One person (or the computer) picks a coin on either end of the chain. Then the computer (or the second person) selects either the new "end" coin or the unchosen one from the previous round. Play proceeds in alternating fashion until no coins remain; the player who collects the greatest dollar amount wins. Click "random numbers" to play the same game with counting numbers in lieu of coins. A discussion of optimal strategies appears below the game.
