Start and choose a level
Start / Continue opens a suitable unfinished level. Filter by difficulty, type and G5–G9 knowledge range. Saving unchanged preferences preserves an eligible unfinished level, even before the first construction.
Lines, circles and snapping
Choose a tool, then drag between two points or tap them in order. For a circle, select the centre first and a point on its circumference second. Nearby points and intersections snap into place. Zoom in when points are crowded. Free points are available on the whiteboard, not arbitrary positions in lessons.
Explanations
The light bulb beside the task opens the idea and step-by-step views. Select a numbered step to highlight the new construction. Return to continue your own drawing; watching a demonstration does not count as an independent solution.
Move, undo and auxiliary lines
Use two fingers to pan and zoom, or drag with the move tool. Undo, redo and reset are on the right of the canvas. Mark, hide or fade auxiliary lines on the whiteboard; hiding preserves dependencies.
Save and import
Whiteboards save locally. Export JSON to edit again; SVG and PNG are images and cannot restore an editable construction. Finish saving in the system file picker before closing it. Cancelling does not create a file. Back up important work separately.
Report a problem
Include the App version, puzzle ID, device, steps to reproduce and an optional screenshot. You send the email yourself; opening a draft does not send it. Avoid passwords, identity documents and unrelated personal information. Contact calminsight@hotmail.com.
