Sudoku and logic games

14 games

Sudoku graded by the techniques each puzzle needs, picture nonograms, minesweeper fields that never need a guess, crates pushed onto lamps, car and water sorting, a rescue puzzle where dug earth becomes bridge bricks, rooms where turning the view joins ledges and brass pins pulled in the right order to fill a newt's pool. Screws go into boxes of their colour, and every plate that falls knocks loose the free screws it passes. A five-letter word game hands the letters you lock to the next board. Each one has a daily puzzle that is the same for every player. Thread puzzles, where you join matching dots until every tile is filled, are here too. A co-op escape room for two shows each player only half of every lock. Arrow puzzles, where one tap sends an arrow off the board and every launch lights the arrows it frees, are here too.

Sudoku and logic games here are puzzles you solve by reasoning, all free to play in your browser. Start with Ninefold Sudoku if you want the classic, or with Valet Parking Jam if you would rather slide cars than write numbers.

Do you want to deduce, or to plan moves?

To deduce, Ninefold Sudoku grades four levels by the techniques a grid needs. Pennant Minefield never needs a guess, because logic alone clears every field. Sepia Nonogram has 48 hand-drawn pictures from 5x5 to 20x20, and Ikat Dot Connect has 240 boards, each with exactly one way to fill it.

To plan moves, Valet Parking Jam has 320 lots with a known best line and three hints each. Kedge Box Pusher has 30 rooms where every crate you dock makes you strong enough to push one more. Tenon Screw Puzzle has 48 boards where a falling plate knocks loose the screws it passes, and Decant Water Sort has 320 racks of coloured liquid.

Which ones ask you to see in a new way?

Oriel Perspective Puzzle joins two ledges that touch on screen, even when one is three blocks higher. Bodkin Pull the Pin is water, lava and sand, where lava cools to stone where it meets water. Tuft Rescue gives you eight roles to hand out to a stream of walkers.

Can you solve logic puzzles together?

Postern Escape Room is for two: each player sees a different half of every lock, and you open 24 rooms by describing what you see. Yarrow Arrow Puzzle lets you race a friend on the same boards.

Frequently asked questions

Which puzzles never need a guess?

Pennant Minefield and Ikat Dot Connect are built so that reasoning alone clears the board. Ninefold Sudoku and Sepia Nonogram each have exactly one solution per puzzle.

Can I undo a mistake?

In most of them, yes. Kedge Box Pusher and Tenon Screw Puzzle have unlimited undo, and Decant Water Sort gives you five undos and one extra empty tube per rack.

Do the puzzles have a daily challenge?

Yes, all of them. Pennant Minefield, for example, gives everyone the same field with a different twist each weekday. Each daily resets at 00:00 UTC.
