How do you play Symmetris?+
A pattern appears on the left half of a grid. You recreate its mirror on the right half by tapping cells. When the right side exactly matches the left side across the center axis, the figure is complete and you score.
What are the rules of Symmetris?+
Fill right-side cells so each mirrors its left-side partner across the vertical center line. Correct fills turn green; fills with no partner turn red and count as errors. Complete the figure to score, and avoid exceeding the error limit.
What does symmetry mean here?+
Symmetry means the left and right halves are mirror images. The center line is the axis: the cell just left of it mirrors the cell just right of it, the far-left cell mirrors the far-right cell, and so on for every row.
How is Symmetris scored?+
You score points for each figure you complete, and a longer streak of completed figures builds a bigger total. Your best streak is saved locally in your browser so you can try to beat it on the next run.
What counts as an error?+
An error is filling a right-side cell that has no matching partner on the left side — that is, a cell that should stay empty in the mirror. Each wrong fill nudges the error counter up, and too many errors end the run.
How many errors can I make?+
The error limit is shown during play. It is generous enough to forgive a couple of slips but tight enough that careless filling will end the run. Clearing a red cell does not add another error, so fix mistakes quickly.
Is Symmetris timed?+
No, there is no countdown. The challenge is spatial reasoning and careful mirroring, not speed. You can take your time to study the left pattern and plan the right half.
Can I play Symmetris on mobile?+
Yes. The grid is responsive and works with touch. Tap a right-side cell to fill or clear it. The controls are identical to desktop, just tap instead of click.
Why are some cells red?+
Red cells are fills that break the symmetry — they have no partner on the left side. Treat red as a warning: either clear that cell or, if you think it belongs, recheck the opposite side of the grid.
What is the best strategy for Symmetris?+
Scan each left-side filled cell, then fill its mirror on the right. Move row by row so you never skip a partner. Verifying the opposite side before each tap keeps your error count at zero.
Is Symmetris good for kids?+
Very much so. It builds visual symmetry awareness and careful observation with no time pressure or violence. Kids learn the concept of mirror images while enjoying a calm puzzle.
Does my best score save between sessions?+
Yes. Your best figure streak is stored locally in your browser, so it persists when you return. Clearing browser data or switching devices resets it, since the score lives on your device.
Can I undo a fill?+
Yes. Clicking or tapping a filled cell again clears it. Clearing a correct green cell is free, and clearing a wrong red cell simply removes the error visually without adding a new one.
How does the game get harder?+
As you complete figures, the patterns become denser and more intricate, with more cells to mirror and trickier shapes. The core rule never changes, so the difficulty grows smoothly.
Is Symmetris free to play?+
Yes. It runs in your browser with no cost, no account, and no download. Open the page and start mirroring immediately. Your best streak stays private on your device.
What skills does Symmetris improve?+
It strengthens visual-spatial reasoning, pattern recognition, and symmetry perception. Because it is low-stress, it also serves as a calming mental exercise between tasks.
