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.
Solitaire — the one everyone already knows
Solitaire is Klondike, played exactly the way you remember it: build the four foundations up from Ace to King, stack the table down in alternating colours, and only a King may move into an empty column. Choose Draw 1 for a relaxed deal or Draw 3 for the classic version that genuinely withholds cards. Unlimited undo means a bad run is never a dead end, and auto-finish sweeps the board once it opens up. Tap a card, tap where it goes — no dragging, which is where most browser solitaire falls apart on a phone.
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.
Sweet Swap and Bubble Burst — the two match-and-clear games
Sweet Swap is a match-3 score attack with 30 moves to spend: swap neighbouring candies to line up three or more, and chain the cascades, since each step of a chain scores higher than the last. Line up four or five and you keep a striped blast, a 3x3 bomb or a rainbow drop that clears an entire colour. Every candy has its own shape as well as its own colour, so it stays readable if you don't distinguish reds and greens easily.
Bubble Burst is the aiming counterpart — fire bubbles up into a hex-packed cluster to pop groups of three or more. The detail that decides runs: knocking out a bubble that others were hanging from drops that whole group, and dropped bubbles score more than popped ones. The ceiling pushes a fresh row down every few shots, so clearing the anchors matters more than clearing the most bubbles.
Circuit Link — routing under a full-coverage rule
Circuit Link looks like simple pair-matching until you hit its real rule: linking every pair isn't enough, because the board only powers up once every single square is covered. That one condition is what makes it a puzzle rather than a tracing exercise — the short, obvious route between two terminals is usually the wrong one, because it strands squares nothing can reach. All ten boards were machine-verified to have exactly one solution, so there's always a single right answer to find.
Lucky 6 — the shortest puzzle here
Lucky 6 is a one-minute commitment: six random numbers are drawn one at a time, and each must be locked into one of six multiplier slots before you're allowed to see the next. You can't undo, and you never know what's coming — so it's a pure test of when to gamble a high slot early versus holding it for a number that may never arrive. Ascending runs and matching pairs pay bonuses on top.
