14 Minesweeper Variants

Here's an excerpt from 14 Minesweeper Variants' Steam description:

The title explains what it is.

Features:

• 14 minesweeper variants, each with four difficulties and hundreds of levels.
• Learning new rule sets and their unique logic.
• In case you need to take notes, there are built-in drawing tools.
• The hint system tells you where to focus on when you get stuck, while it does not simply tell the solution.
• Every level can be completed by logic. Guessing is not required.
• The puzzles are procedurally generated. We tried a few programming and game design techniques in this game. I promise it doesn't feel like any other procedural generated game before.
• And there's more to explore.
