Perla Loop

Check both sides of each pearl

At a black pearl, the turn belongs on the pearl itself, with the adjacent points straight on both sides. At a white pearl, the line passes straight through the pearl and must turn at an adjacent point on at least one side. Drawing a plausible local bend is not enough if the opposite side breaks the pearl rule.

Trace the entire path after connecting a group of pearls. A small closed loop cannot be accepted while another pearl remains outside it. Keep revisions local with Undo, then check that the final path is one loop with no branches or crossings.

Follow the black and white pearls

Draw a single closed loop through every pearl, without a crossing or branch. At a white pearl the loop goes straight, then turns at an adjacent point on at least one side. At a black pearl it turns on the pearl and continues straight at the adjacent points on both sides. A line can satisfy one pearl while still conflicting with another, so check the complete loop before treating a local segment as final.

Draw, revise and return

Native hints add or correct a segment. Undo lets you revise a recent decision. The current board and Undo history can be restored in this browser; they do not synchronize to another device. Use the portal’s Pause control for a break and resume the same embedded game. Theater and Fullscreen enlarge the player without replacing the puzzle.

A finite collection of boards

The reviewed build retains 13 original boards in 5×5, 6×6 and 7×7 sizes. Rotations and reflections produce 104 orientations; these are not 104 separately created boards. The native daily selection follows the local date. Personal records are local, with new unassisted best times tracked separately from hinted play. There is no online opponent or global ranking.
