Pop it is a fidget toy which became popular in the beginning of 2021 due to TikTok.
The game is simple and has the following ruleset:
- Decide who start
- Choose a row and choose the number of cells you want to pop (from 1 to the entire row)
- Opponent does the same
- Whoever has to pop the last unpopped cell, loses!
This can be regarded as a version of the game of Nim.
I made a small web-app in which you can play against the algorithm and try to win :-)
