Free Browser Puzzles

Pick a puzzle, take five minutes

Four small games that run entirely in your browser. No account, no download, nothing to install — and your scores stay on your own device.

2048

Slide the tiles, merge matching numbers and try to build a 2048 tile.

Connect each pair of coloured dots with an unbroken path, then fill every cell.

Guess the hidden five-letter word in six tries using the colour feedback.

Clear an 8×8 minefield using the numbers on the safe squares. Ten mines to flag.

Micro Tools

A focus timer, a matrix calculator and a rhyme finder. All three run in your browser — no account, nothing uploaded.

Work in a 25-minute block, take a five-minute break, and a longer one every fourth round.

Add, subtract and multiply 2×2 or 3×3 matrices; find the determinant, transpose and inverse.

Type a word and get the words that share its ending sound.

Brain Notes

Short pieces on memory, attention and studying. Each one ends with something you can try in five minutes.

Why your opening word matters less than you think — and the guess-two mistake that costs most players a row.

Puzzle games make you better at puzzle games. Whether they make you better at anything else is a much harder question.

Forgetting is not a flaw in your brain — it is a feature that keeps the useful things.

Retrieval practice, immediate feedback, and a natural ending — why a five-letter puzzle satisfies.

A change of mental scenery between study sessions, and why the break has to end to count as rest.
