Daily Brain Games: Logic, Number, Spatial and Memory Puzzles

Quizebra Brain is a set of four free daily brain games: Logic, Numbers, Spatial and Memory. They need no knowledge at all, only thinking: each puzzle hides a rule in a picture or a set of numbers, the kind of brain teaser an IQ test is made of. Logic, Numbers and Spatial give you three puzzles a day, easy to hard, with sixty seconds and one try each, scored on your total time. Memory gives you five puzzles with no clock, scored on how many you get right. Everyone in the world gets the same puzzles each day, with a leaderboard for that day. No account, no sign-up, no ads, and unlimited practice once the daily set is done.

Do I Need to Know Anything?

No. Nothing here asks for a fact. Everything you need to solve a puzzle is on the screen, and the job is to find the rule behind it. That is the difference from the geography and football games, which are about what you know; these are about what you can work out.

Is This an IQ Test?

No. The puzzle types are the ones IQ tests use: a matrix with a missing tile, a number series, a shape turned or folded, a picture to hold in your head. But a test is standardized and scored against a norm group, and nothing here is. You get a time or a count and a place on the day’s leaderboard, not an IQ. If you enjoy IQ tests, you will probably enjoy these.

How Hard Are the Puzzles?

Each day climbs: in Logic, Numbers and Spatial the first puzzle is easy, the second medium and the third hard. Sixty seconds is plenty for the easy one and tight for the hard one, and there is one try, so a wrong answer loses the puzzle and counts as the full minute. Memory has no clock; there the difficulty is how much you can hold, from a single picture to a sequence shown one after another.

Where Do the Puzzles Come From?

From rules written for this site, not from a book or a test bank. Each puzzle type is one rule and a script that builds puzzles from it, and every puzzle was checked by hand before it went in, so it has one clear rule and one right answer. In Logic, Numbers and Spatial the wrong options are built to look like what a nearly right rule would give, so guessing from the look of the tiles rarely works. The pools hold 270 Logic, 660 Numbers, 163 Spatial and 500 Memory puzzles, split by difficulty. In Logic and Numbers the rule is explained after every puzzle, right or wrong.

Which Game Should I Start With?

Memory if you want no clock. Logic if you know IQ-test matrices: find what changes from tile to tile. Numbers if you like series and grids, Spatial if you can turn things in your head. Playing all four each day is how you become the Daily BrainWhiz.

When Do the Games Reset?

At midnight London time. Each game then has a fresh start and a fresh leaderboard. If you make the day’s top five, your result goes on the leaderboard under a name you type, or an automatic one if you leave it empty.

Quizebra also has six geography games, six football games and four chess games built the same way.
