Hi Ho! Cherry-O

Hi Ho! Cherry-O is a children's put and take board game currently published by Hasbro[1] in which two to four players spin a spinner in an attempt to collect cherries. The original edition, designed by Hermann Wernhard and first published in 1960 by Whitman Publishers, had players compete to collect 10 cherries. During an update in 2007,[2] the rules were updated to include a cooperative play variant, where players cooperate to remove all fruit from the board before a bird puzzle is completed. In 2015, Winning Moves published a classic edition.

Gameplay

Each player starts the game with an empty basket and 10 cherries on his/her tree. Players take turns spinning the spinner and performing the indicated action. The spinner is divided into seven sections:

  1. Take one cherry off of the tree
  2. Take two cherries off of the tree
  3. Take three cherries off of the tree
  4. Take four cherries off of the tree
  5. Dog: Return up to two cherries to the tree. If the player has no cherries, their turn is skipped.
  6. Bird: Same thing as the dog
  7. Spilled basket: Replace all of the cherries on your tree

The first player to collect all the cherries from his/her tree and call "Hi Ho! Cherry-O" wins the game.

Analysis

The game length can be determined using a Markov chain, yielding the following results:[3]

  • Minimum game length: 3
  • Average game length: 15.8
  • Maximum game length: Unbounded
  • 25th percentile: 7 moves
  • 50th percentile (median): 12 moves
  • 75th percentile: 21 moves
  • 95th percentile: 40 moves
gollark: It would have been much more sensible to use 1LC/2LC/3LC but noooo...
gollark: TLC does three bits a cell, so you get 2³ = 8 voltage levels, etc. - you trade off endurance and speed for density.
gollark: The issue with it is that the flash memory wears down in some way after a bunch of program/erase cycles, so it has trouble reading/writing accurately or something, and this is a greater problem for MLC than SLC because it has to read finer gradations.
gollark: I mean, yes, the naming is weird.
gollark: MLC is two bits a cell, so it has to distinguish *four* voltage levels. This means you get twice the density.
