Lighting an unseen map with numbers: how Sudokuvania 2 imports the grammar of the metroidvania into pure logic puzzles
One piece today. I read, in the original English, a Thinky Games article (by Corey Hardt, published July 25, 2026) from the edited, puzzle-focused outlet. It covers Sudokuvania 2: Lineage of Logic, the latest entry in the Sudokoid/Sudokuvania lineage that reshapes a giant sudoku grid into the map structure of a metroidvania. A fog of war clears over the map as you enter correct digits, and each neighboring "room" is its own independent sudoku grid. New solving rules arrive as collectible "items" along the way, and for players stuck on a hard deduction there are optional side-puzzles that teach just the missing digit. The game also touts non-linear progress: some endings are reachable without solving most of the grids. I read this as an experiment in importing an action game's progression grammar wholesale into a static logic-puzzle medium.
