Puzzle games, the genre that ages best

Puzzle games are the longest-lived category in gaming, full stop. Tetris (1984) is still actively played and refined. Sudoku (popularised in the 1980s but invented earlier) remains a staple of physical and digital play. The match-three formula is roughly thirty years old and still dominates mobile arcade charts. Solitaire predates computers entirely and is still on every desktop OS by default. Browser-playable puzzle games inherit this longevity because the format is about thinking, not reflexes. A well-designed puzzle is just as compelling on a phone in 2026 as it was on a console in 1989, which is a thing you cannot say about most other game categories.

What I look for in puzzles we publish: a clean ruleset (you should be able to explain the game in a single sentence), a difficulty curve that introduces complexity gradually instead of dumping it all on you, meaningful progression that isn't padded, and a fair chance to undo a misclick. The puzzle catalogue below favours games that respect your time. No energy systems. No forced ad interstitials between levels.
