What this odd one out game is

Each round shows a grid of small figures, and exactly one of them has no match. On levels 1 to 10 all the others are identical. On levels 11 to 15 they form two groups. You find the odd one and tap it. One tap per round, right or wrong, and then the next grid appears.

The figures are simple marks drawn on a three by three dot grid, a bit like a letter L, a hook or a corner. None of them looks the same when you flip it or turn it by a quarter, so a mirror or a quarter turn is always visible if you look closely enough.

Many "find the odd one" games online use color, one square that is a slightly different shade of green. This one does not. The odd figure can be turned, bigger or smaller, lighter, mirrored, or drawn with one or two dots changed, and it never differs by hue alone. That keeps the game playable for people who see colors differently.

What changes from level 1 to 15

Levels 1 to 10 make the grid bigger and the difference smaller. Level 1 is a 3×3 grid with 6 rounds, and the odd figure is either turned by a quarter or clearly bigger or smaller. Level 2 adds a changed shape. Level 3 moves to 4×4 and adds mirrored figures. From level 4 all five kinds of difference can appear, including a lighter figure drawn in weaker ink.

Then the differences shrink. A turn goes from 90 degrees down to 45, 30, 20 and finally 15 degrees on level 10. The size difference shrinks to less than half of what it was on level 1. A lighter figure starts at half the ink on level 4 and ends at three quarters of the ink on level 10. A shape change starts with two dots and ends with one. The grid grows to 5×5 on level 6 and 6×6 on level 9.

Levels 11 to 15 change the kind of search. The figures now come in two groups. One group is plain, the other carries two changes, for example turned and bigger. The odd figure carries only one of those changes, so it shares one feature with each group and has no twin. You cannot find it by looking for a single feature. These levels do not use lighter figures. The grid steps back to 4×4 on level 11 because this is a new kind of task, then grows again to 7×7 on level 15, with 49 figures and 12 rounds.

Every round has a time limit. It starts at 5.5 seconds on level 1, falls to 4.2 seconds by level 10, goes back to 5 seconds on level 11 and ends at 4.1 seconds on level 15. Levels 1 to 5 are free. All level settings are our first guess and have not been tested on players yet.

How the points work

A right tap gives 10 points and a speed bonus of up to 10, counted from the moment the grid appears. A tap in under 0.2 seconds earns the full bonus. After that it drops by one point for every 0.4 seconds and reaches zero at 3.8 seconds. The bonus falls more slowly here than in our other games, because the biggest grid has 49 figures to look through. That step is a first guess too.

A wrong tap costs a life, and so does a round where time runs out. Each level starts with three lives. After a wrong tap the game marks the odd figure so you can see what you missed, and moves on. If a life is still left after the last round, the level is cleared, so two lost lives are allowed.

The most a level can give is 20 points per round, 120 on level 1 and 240 on level 15.

What counts as a good result

We do not publish norms or compare you with others. After each level the results screen shows your points, the speed bonus, the time, your mistakes and your previous best on that level. A good result is one that beats your best on that level.

Levels 9 and 10 put small differences on a 6×6 grid, and level 11 changes the task. We expect both to feel like a step up, but we have not checked that with players yet. On levels 11 to 15, a bigger grid probably matters more than on the early levels, since no single feature gives the odd figure away and you have to look at the figures one by one.

A few tips

Let your eyes rest on the whole grid for a moment before you start scanning. On the early levels the odd figure may jump out on its own.

On later levels, scan row by row. A 15 degree turn or a small change in size is easy to miss with a quick glance.

On levels 11 to 15, first work out what the two groups look like, then look for the figure that belongs to neither.

Questions

Is the odd one out game free?

Levels 1 to 5 are free. The full version opens all 15 levels. It is a one-time purchase with no subscription.

Is this a find the different color game?

No. The figures differ by turn, size, lighter ink, mirroring or a small change of shape, never by hue. You do not need to tell colors apart to play.

Can I play it online without installing anything?

Yes, once it launches. It will run in the browser on a phone or a computer, and inside Telegram. Levels 1 to 5 are free.

How many figures are on the grid?

From 9 on level 1 to 49 on level 15. The grid is 3×3 on level 1, 6×6 on level 10, 4×4 again on level 11 and 7×7 on level 15.

Is there a time limit?

Yes. Each round has one, from 5.5 seconds on level 1 to 4.1 seconds on level 15, with a step back up to 5 seconds on level 11. When time runs out you lose a life and the next round starts.

Can I play it with a screen reader?

Not really. The game is about seeing the figures, and describing them in words would give the answer away. The game says this before you start and suggests other games instead.

Will it make me more observant?

We make no such claim. The points show how you did in this game.
