I think even for "kid games", the ktuberling and klettres games have limited appeal and target audience. I don't miss them on my machines.
If you do miss them and want them back, you can use the kde.SlackBuild script to build and install them again, with not too much effort.
You'd need a copy of the kde slackbuild source directory, eg:
https://mirrors.slackware.com/slackw...ource/kde/kde/
Then get the sources for ktuberling and klettres from kde and put them both in the src/applications sub-directory of the kde slackbuild directory.
Older sources, 15.0 vintage, are here:
https://kde.org/info/releases-21.12.1/
Newer version, -current as of today:
https://kde.org/info/releases-22.12.0/
Then run the kde.SlackBuild, which will build (and install) both packages.
Code:
./kde.SlackBuild applications:klettres,ktuberling
I point out both source versions because the newer klettres didnt build when I tested it on 15.0 system. ymmv
At least then you can scratch your "Potato Guy" itch
