Pair One pair with three distinct cards. High card breaks ties. This is any hand which doesn't qualify as any one of the above hands. If nobody has a pair or better, then the highest card wins. If multiple people tie for the highest card, they look at the second highest, then the third highest etc.
Poker is, after all, a gambling game.
After that players bet into the pot in the middle. Since you owed the pot 15 cents for calling and 25 for your raise, you would put 40 cents into the pot. Betting continues until everyone calls or folds after a raise or initial bet. In the group I play in, we ante a nickel. The maximum first bet is fifty cents, and the maximum raise is fifty cents.
