I have the following problem my grandpa always played such a game on his laptop but this page no longer exists do you have suggestions for any browser games, for example. So chess, checkers, poker (no money) or stacking games where you have to stack things!
Ok, here are a few suggestions for games like this:
chess
lady
Poker with no money
Sokoban
One of many pages with browser games: https://www.spielaffe.de/Spiel/Sokoban
You have internet yourself and can search for "browser game" or something similar there, right? What system does your grandpa play on anyway? Linux? Windows? Mac? So in German: What kind of system is running on the laptop?
Download it to the play store
You can usually download it from the apps
PC Windows
I made my grandma's shortcut too playful. She often plays the variants of jewels / candy crush
And what if these pages no longer exist at some point?
