Puzzle games reward patience over reflexes: spot the pattern, plan the move, rule out the unsafe square before you commit to it. Every game below runs straight in the browser — no app store, no account, no ads to sit through before you start.
Word Vault — the daily word puzzle
Word Vault gives everyone the same 5-letter word each day and six guesses to find it, with color-coded feedback after every attempt. It resets at midnight, so there's exactly one puzzle a day to compare notes on.
2048 and 2048 3D — tile-merging under pressure
2048 is the classic: slide tiles, merge matching numbers, try to reach the 2048 tile before the board fills up. 2048 3D is the same core idea rebuilt with a real 3D board you can rotate — a genuinely different feel for a puzzle you probably already know.
Sudoku and Minesweeper — slower, more deliberate logic
Sudoku and Minesweeper are both here in their untouched classic form — no timer pressure forcing a mistake, just pure deduction. Good picks when you want to think instead of react.
Hextris — puzzle speed at arcade pace
Hextris takes the falling-block idea from Tetris and wraps it around a hexagon, rotating instead of shifting left and right. It's faster and more reflex-driven than the rest of this list, closer to a puzzle/arcade hybrid.
Marble Maze — a real 3D tilt maze
Marble Maze is the odd one out here: a physics-based 3D maze you tilt your way through, rather than a grid you click or drag. Worth trying if the rest of this list feels too flat.
