I recommend https://openrct2.io/ - it’s a fan made open source reimplementation that adds many changes, among them multiplayer, mods, UI improvements, bugfixes and so on. For installation you’ll need a copy of the original RCT2 game. It also supports RCT1 scenarios and graphics.
Sounds interesting!
I recommend https://davidnhill.github.io/JSMinesweeper/ - it has a no guessing mode, a fast mode to skip obvious choices, can show hints if you need any, is free and works in your browser.
I also recommend https://zblip.itch.io/mine-of-sight - it’s more complex than Minesweeper and has different types of Minesweeper-esque clues combined into a single game. It’s also free and runs in your browser.
Have you tried Unciv? https://yairm210.itch.io/unciv It’s a free and open source remake of Civ 5 and already supports many of its features. I really enjoy playing it as it’s much less hardware intensive which makes for near instant loading times and keeps the computer nice and cool on hot summer days.
