12 free puzzle games you can play in your browser with no download

Quick ones, under five minutes

• Sudoku 4x4: the full game shrunk to sixteen squares, and the best way to teach someone the idea.
• Flood It: fill the board from the corner before your moves run out. One decision per turn, and all of them matter.
• Boggle 3x3: nine letters, as many words as you can trace. Over before your tea cools.
• Wordle: one word, six guesses, and the rest of the day to think about it.

Proper sittings, ten to twenty minutes

• Sudoku: the daily grid on three levels, generated fresh each day.
• Pips: a tray of dominoes and a board of regions, each demanding a sum, an inequality or a match. Every puzzle has exactly one answer.
• Nonograms: numbers along the edges hiding a picture, solvable by logic alone.
• Minesweeper: still the best deduction game ever bundled with an operating system.
• 2048: slide, merge, and watch a perfectly good board collapse because you pressed up once.

Long ones, as long as you want

• Killer Sudoku: cages and sums on top of the usual grid, for when plain Sudoku has stopped resisting.
• Mahjong Solitaire: a stacked layout to clear pair by pair.
• Solitaire: Klondike, draw one or draw three, exactly as you remember it.
• Boggle 5x5: twenty five letters and more words than you will find in one go.
