Rangoli Mirror teaches symmetry by drawing. A dashed vertical line marks the mirror. Marigold-coloured segments on the left (or the highlighted side) are the pattern to copy; you complete the design on the other side so both halves match.
Tap one dot, then tap a neighbouring dot to draw a straight segment between them. Repeat the same segment mirrored across the line. The puzzle checks after each stroke; when every required line exists on both sides, the level finishes on its own.
Worked example
If the source side shows a diagonal from the centre dot up-and-right, locate the mirror image of both endpoints and draw the matching diagonal up-and-left on the far side. Short paths build into fuller rangoli petals one stroke at a time; you do not need to plan the whole picture before you start.
Strategy tips
Count dots from the mirror. A dot two grid steps left of the line lands two steps right on the opposite side at the same height. That spacing rule is steadier than eyeballing angles.
Complete one petal at a time. Finish the mirrored strokes for a single marigold shape before jumping to a distant corner of the board.
Use undo if your line zigzags. Only straight segments between neighbours count; if a stroke feels wrong, clear it and reconnect the proper pair.
Later puzzles add more dots and longer paths, but the mirror rule never changes. The calm palette and large tap targets suit ages five and up with a little help reading the first instruction screen.
If a stroke looks correct but the puzzle does not finish, check whether you mirrored both endpoints: a line one dot off on the far side leaves the pattern subtly uneven even when the near side matches the sample.
Work outward from the mirror line toward the edges; the outer dots have fewer neighbours, so mistakes there are easier to spot before you duplicate them.
