Get a word and decide based on whether the sum of the alphabetical indexes (a=1, o=15, ect) is even or odd. To get the word, explain the above to the other person and then say you’re going to ask a question of them that they must answer quickly (to avoid computing the answer and then lying). Then say “what’s the name of your hometown” or something.
Both of you pick a number in secret. If the sum is even, you win. If the sum is odd, they win. Say the numbers at the same time to prevent cheating. Redo if someone stutters.
Rock-Paper-Scissors. Normally pretty easy to predict the other person’s actions, but if the stakes are high enough both players will climb to high enough layers of I-think-you-think-I-think that it’s equivalent to #2.
Pick a narrow axis like age, height, shoe size, latitude of birthplace, ect. Whoever has the bigger number in that axis wins.
