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.

Cube Fold
Spatial-reasoning puzzle. Fold a 2D net into a 3D cube and predict which face ends up where. Sixty levels.
Binary Board
Binairo logic puzzle. Fill the grid with 0s and 1s; equal numbers per row and column; no three consecutive same values.
Parity Flip
Lights Out variant. Flipping one cell flips its neighbours too. Convert a starting pattern to a target with minimum flips.
Memory Grid
Bare-minimum tile-matching memory game. Flip two tiles at a time to find pairs. 4x4 easy through 8x8 hard.
Lock Pick Mini
Simple lockpicking timing puzzle. Find the sweet spot on each pin and apply tension to set it. Time-attack mode included.
Unscramble Mini
Basic anagram puzzle. The game shows scrambled letters; you arrange them into an English word. Three to eight letters.
