Bananas Are Berries. Strawberries Aren't.

Bananas are berries. Strawberries aren't โ€” they're accessory fruits, with the true fruits being those tiny seeds on the outside. Raspberries aren't berries either โ€” each bump is a separate drupelet with its own seed.

The rose family, Rosaceae, dominates the fruit world: apples, pears, cherries, peaches, plums, strawberries, raspberries. A peach and a cherry are closer relatives than either is to a grape. But some connections cross supermarket aisles entirely: coconuts, dates, and acai are monocots, more related to grasses than to apples. Pineapples are bromeliads. Kiwifruit and blueberries share an order with tea plants.

76 fruits organized by APG IV botanical classification. The produce aisle will never look the same.

Did you know?

  • *Bananas are botanically classified as berries, while strawberries, raspberries, and blackberries are not true berries at all.
  • *Almonds are stone fruits in the same subfamily as peaches, plums, and cherries.
  • *Apples, pears, cherries, peaches, and strawberries all belong to the rose family, Rosaceae.
  • *Pineapples are bromeliads, making them more closely related to Spanish moss than to any other common fruit.
  • *A fig is technically an inverted flower cluster, with the tiny flowers and seeds hidden inside the fleshy structure we eat.

What is GuessKin?

GuessKin is a free daily guessing game built on real-world taxonomy. Choose from over 20 categories and try to identify the mystery fruit. Each guess reveals how closely related your answer is to the target through a shared classification tree.

How does it work?

Every fruit in GuessKin sits on a taxonomy tree โ€” a branching hierarchy that shows how things are classified and related. When you make a guess, the game shows you the nearest common ancestor between your guess and the answer. The closer that ancestor is to the answer, the warmer you are. The tree visualization grows with each guess, narrowing down where the answer lives and helping you triangulate.

How to get the best score

  • โ€ขFewer guesses is better. The ideal game is guessing it in 1. Every guess counts against your score.
  • โ€ขSpeed matters too. The timer starts on your first guess. Quick, confident answers are rewarded.
  • โ€ขRead the tree. Each guess gives you real taxonomic information. Pay attention to which branch the answer is on and which branches you've already ruled out.
  • โ€ขStart broad, then narrow. Your first guess splits the tree. Pick something that gives you maximum information, then drill into the revealed branch.

Each GuessKin category uses a real classification system. These aren't made-up groupings โ€” they're the same systems scientists and specialists actually use. New categories are added regularly. Every category is free, with no accounts and no ads.
