How do you handle different cultures counting their fingers differently? Like in the first image it could be read as 2025, or it could be read as 1001215, or a couple of other ways. Saying ‘count’ of fingers might be better, but still not helpful if english is not their native language.

EDIT: Fixed miscount, lol

Honestly, I did not account for variance in the counting of fingers.

Which cultures would count as 18 and how do they reach there? do closed fingers mean 10 or 5 to different cultures?

The library only provides the image and answer, the text and hints to require input are in your control so could use the appropriate instructions and wording for the culture and language.

Thank you for a great point regardless, I will do some research on it and update the assets to be more clear as necessary.

I’ve personally met people that count with fingers in base-2 starting with the thumb as 1, and people who count using their thumb placed on the parts of the fingers between the joints (starting with pinky near hand, so 3 per finger, 4 fingers, so they count to 12 on each hand), and I’ve seen other popular methods online as well.

From UI perspective:

• I will definitely make the text to describe each opened, clear finger count as one
• 0 is the special case of shape
• Add an example of challenge and the answer in a question mark help text

Library:

• maybe completely remove 0 from the library to prevent confusion
• Add guards for generation between sane numbers

In the first picture there are 4144. Obviously.

Nothing is said about them need to be stretched or folded, so you see 4 fingers and one thumb on 3 of them, one finger and a thumb on one.

You guys are more literal than the robots

joking aside addressing the clear instructions issue as we speak

We are developers.

It’s our job to recognize important edge cases before they hot production.

I am only joking, I appreciate the help!

with 0.1.4

• the 0 edge case is gone
• added actual integration tests to solidify the stitching part

Now time to update the elxsy and clear the instructions with help

If culturally it is too complex to make a solution that suits them all I am wondering if you could use pictures of random objects, like coins, pencils, forks, spoons, bottles, etc. for the same purpose. It may even be harder for AI engines to break.
