7 Billion Humans Solutions

Community solutions for the game 7 Billion Humans.

The aim is to have all the solutions for the best speed and/or size seen on the OCD+ challenge stat page. Please feel free to submit any improvements you find.

Submissions

Either open a pull request or post on the Steam thread.

Solutions Folders

Folder	Success rate	Contents
Solutions99+	99% or more	The main table. Every solution here works essentially every time.
Solutions50+	50% to 99%	Solutions that beat the Solutions99+ entry but do not always succeed.
SolutionsLowPercent	under 50%	Solutions that beat the entries above but only succeed occasionally.

A solution only belongs in Solutions50+ or SolutionsLowPercent if it is strictly better (fewer commands, or fewer steps) than the entry in the folder above it. If it merely ties, the more reliable solution wins and the less reliable one is not listed.

File Naming Rule

Year NUM - NAME (TYPE).txt

NUM = 02-68 (years 08, 27 and 45 have no OCD challenge, so they have no solutions)

NAME = The puzzle's name

TYPE = Speed, Size or Both

Run check_names.py to confirm, and check_readme.py to confirm the tables below match the solution files.

See CONTRIBUTING.md for how sizes and speeds are measured, how solutions are ranked and how credit is given.

+99% Solutions

Size is the number of commands in the solution and Speed is the number of steps it takes to run; a ~ prefix means the solution is random and the value varies. The value a solution is optimised for is shown in bold and carries a marker comparing it with the shortest/fastest known solution on the OCD+ challenge stat page:

❌ = worse, ✔ = same, ➕ = better, ➖ = sometimes hits speed.

📋 marks a solution that cannot be typed in the game's editor and has to be pasted in.
