Shape Fit

Look at the target on the left and adjust the blue shape on the right. Match Rotation changes direction, Match Size changes size, and Match Both lets you adjust both. The two shapes share the same centre and equally sized frames. You do not need to move or flip them.

Use a slider for larger changes, then the fine adjustment buttons below it. Rotate by 1 or 5 degrees, or resize by 1%. You can also focus a slider and use the arrow keys. The size range is 50–150% of the starting shape.

The target and your shape stay side by side until you confirm. Select Confirm this shape to reveal the actual overlay, overlap percentage and round score.

Overlap is the area shared by the two shapes divided by their combined area, counting the shared area once. Multiply that ratio by 100 and round to get the round score. Six rounds add up to a maximum of 600 points. The displayed percentage uses one decimal place; scoring uses the unrounded ratio.

There is no speed bonus or time limit. Time is recorded so you can look back at your play. Your score, title and personal best for each mode depend only on overlap. Take your time and confirm when you are ready.

Reset adjustments restores the starting direction and size for the same puzzle, while time keeps running. Restart this round asks for confirmation, then replaces only this round with a different shape at the same difficulty and resets its timer. Completed rounds and later puzzles stay unchanged.

Each of the six difficulty stages has 100 shapes. Later rounds have more contour features to compare. New games avoid recently played shapes, and there is no daily limit. Replaying the same six puzzles keeps the completed game’s original mode and shapes.

Your result shows all six confirmed shapes overlaid on their targets, with each round’s score, overlap percentage and time. Selecting a mode for your next game does not change the completed result or shared image. A shared link opens the same six puzzles in their original mode.

Your title uses the total score from all six rounds. All three modes share the same title bands, while personal bests are saved separately for each mode. Your first completion is celebrated separately from an improved best. A tie does not count as a new best.
