Puzzle Games
Thirteen puzzle games covering logic, matching, maths and a couple of famously unfair quizzes. No time pressure in most of them, which makes this the calmest category on the site.
All 13 games run in a browser tab with nothing to install.
What is here
Puzzle games in a browser tend to split into two groups. There are the ones that give you a rule and let you work out its consequences, and there are the ones that give you a grid and ask you to keep it tidy. Both are represented here, and the two require very different states of mind.
The logic games are Bloxorz, Nuts and Bolts Puzzle and Jewelanche. The tidying games are 2048, Block Blast, Tile Match, Hexa Puzzle, Cake Match Puzzle and Mahjong. The tidying games are better for short breaks; the logic games are better if you want to actually think about something.
Where to start
Bloxorz is the best game on this page and the one worth committing to. You roll a rectangular block around a floating grid trying to drop it into a hole, and the puzzle is entirely spatial: you have to picture how the block will end up oriented several moves ahead. It gets hard quickly and it never cheats.
2048 is the other essential. It looks like a matching game and behaves like a strategy game, because every move shifts the whole board and a careless swipe can cost you a run you have spent ten minutes building. The trick most people find on their own eventually is to keep your highest tile locked in one corner and never move in the direction that would dislodge it.
The Impossible Quiz
The Impossible Quiz and The Impossible Quiz 2 are not really puzzle games. They are jokes structured as quizzes, where the correct answer is usually a pun, a trick, or a reference to a question you answered several minutes ago. They are frustrating by design and much better played with someone else, because two people will spot different tricks.
Treat them as comedy rather than as a test and they are among the most entertaining things on the site. Treat them as a fair challenge and you will not enjoy them.
Maths puzzles
Math Duck and Math Experta are the two games here built around arithmetic rather than logic. Math Duck wraps its sums inside a small platformer, which works better than it sounds, because you are solving problems to open doors rather than to fill in a worksheet.
