Smashing together people to win at dating? Isn't that just Tinder?

Tinder goes in two directions. This would go in 4 directions. Swipe up to send them to your friends, down to your enemies, left to the void, right to you.

You start with 2048 single people, and have to act as matchmaker to pair them off into married couples who each produce at least one child. A generation later, you take the 1024 first-borns of each couple and have to pair them off too, into 512 new pairings.

Repeat that long process until there is just one couple left, whose first-born you then propose to. Having lived long and healthily enough to complete this game, you must have some very desirable genes and/or wealth, and you'll be good friends with basically all this person's ancestors, so there's a strong chance they'll say yes, despite the age difference.

Match fruits until you get a date?
