Hol-jjak (Odd or Even)

Record vs AI

Each player starts with 10 marbles.
The hider secretly grabs one or more of their own marbles.
The guesser calls odd or even for the number of hidden marbles and puts up some of their own marbles. The most you can put up is the smaller of the two players' marble counts.
A right guess takes that many marbles from the hider; a wrong guess gives that many to the hider.
Hider and guesser swap every round. Collect all the marbles to win! After 50 rounds, whoever has more marbles wins.
In 2-player mode the screen is covered before each step, so take turns without peeking.
Marbles are just for play. No money is involved.
